Known issues and limitations

List of known issues and limitations in Cloud Pak System Software.

  • Adding HMC in PowerVC shows compute node available but its deployment fails with a storage error.
    Problem
    Virtual instance deployment that is failed with the error displayed as CWZIP2018E. The group deployment operation failed because deployment of at least one member of the group fails with error ${vmname} : CWZIP2016E and the deploy operation failed error appears as
    Deployment error: CWZIP8003W The virtual machine is in an error state - No valid host was found. No suitable host could be found due to the storage configuration. Please ensure there are available hosts in the Storage Connectivity Group and that there is sufficient storage capacity for this operation and retry your request.
    Root cause
    The storage connectivity group is Inactive in PowerVC. This issue is seen when compute node is re-registered to PowerVC.
    Resolution
    Verify that fiber channel ports connectivity type is set to vSCSI and wait until Storage connectivity group PureApp_Default is OK in PowerVC.
  • During installation Servicd64 struck ‘Failed offline’ state
    Problem
    During installation Servicd64 struck a ‘Failed offline’ state.
    Resolution
    To resolve this issue, do these steps:
    1. After the script completes, ensure that the psm services are in online state by running the psm info all command.
    2. If Service64 is not in online state, run the following commands to bring the Service64 to online state. If Service64 is in Failed offline state, then run psm reset Service64 command to move it to starting state and then run the following commands:
      • /data/purescale-install/tsa/runTSAServerCommand.sh stop ipas-float- db2instance-db2inst 2>&1 | /data/purescale-install/tsa/tsalogger.sh ipas-float- db2instance-db2inst stop ; (exit $PIPESTATUS)
      • /data/purescale/db2_11.5.8.0/bin/db2gcf -s -i db2inst
      • /data/purescale-install/tsa/runTSAServerCommand.sh start ipas-float- db2instance-db2inst 2>&1 | /data/purescale-install/tsa/tsalogger.sh ipas-float- db2instance-db2inst start ; (exit $PIPESTATUS)
      • /data/purescale/db2_11.5.8.0/bin/db2gcf -s -i db2inst
    3. Wait for 20 minutes to get the rest of the services to online state, which states all service of PSM will be in online (green) state.
    4. If service64 does not start and the following error appears in the /var/log/purescale/ipas.tsaserver/ipas-float-database-ipasdb.log file.
      <start>  utils.process  | [stderr] FINER: Unable to query database with current connection object
      
      [08-24-24 10:36:13] 3313  <start>  utils.process  | [stderr] com.ibm.pdq.runtime.exception.DataRuntimeException: [pdq][0][2.7.116] CWPZC9001E: Could not obtain Connection from org.apache.commons.dbcp.PoolingDataSource;  Caused by: com.ibm.db2.jcc.am.SqlNonTransientConnectionException: DB2 SQL Error: SQLCODE=-20157, SQLSTATE=08004, SQLERRMC=DB2IPAS;QUIESCE DATABASE;;, DRIVER=4.14.113
    5. Do these steps to bring the services to the online state:
      • /data/purescale/db2_11.5.9.0_special_43682/bin/db2gcf -s -i db2inst | grep 'DB2 State'
      • /data/purescale/db2_11.5.9.0_special_43682/bin/db2gcf -u -i db2inst
      • resetrsrc -s "Name?='ipas-float-db2instance-db2inst'" IBM.Application
  • Comparing physical core and memory on CPS UI with HMC shows a mismatch IN data result.
    Problem
    CPU utilization of the compute node is displayed as 0.
    Root cause
    The query job is not able to calculate the compute node CPU utilization from HMC.
    Resolution
  • The storage connection does not get registered in PowerVC after PowerVC VM is rebooted.
    Problem
    Virtual instance deployment that is failed with the error displayed as CWZIP2018E. The group deployment operation failed because deployment of at least one member of the group fails with error ipas-vm25-187-064-118-OS_Node_1.11725422770404: CWZIP2016E and the deploy operation failed error appears as
    Deployment error: CWZIP8003W The virtual machine is in an error state - Build of instance e3e5de5e-9807-4bbd-b57c-526b17045ae2 aborted: Failure prepping block device.
    Root cause
    Storage provider connection needs manual refresh after PowerVC reboot.
    Resolution
    In PowerVC UI, go to storage list > edit connection and then save the connection by entering password. This establishes the storage connection again. .
  • Service 55 shows the Stuck online state intermittently after a failover or after a Platform System Manager (PSM) restart or shutdown
    Problem
    Service 55 shows the Stuck online state intermittently after a failover or after a Platform System Manager (PSM) restart or shutdown. Therefore, High Availability (HA) results in error or offline states.
    Resolution
    To resolve this problem, log in to the Platform System Manager (PSM) console and run the following command from the leader Platform System Manager (PSM):
    psm automation reload
  • Bring your own OS image and customize by using the AIX OS pattern kit is not supported.
    Problem
    Bring your own OS image and customize by using the AIX OS pattern kit is not supported.
    Resolution
    Clients must use the OS image that is provided by the Cloud Pak System.
  • Db2 pattern does not get deployed by Self-Service (read-only user) with saved Fenced user and Instance owner passwords
    Problem
    As a read-only user, you cannot deploy the Db2® pattern when the Fenced user and Instance owner password fields are already saved with the password in the Pattern Builder page.
    Root cause
    When you open any Db2 pattern with the already saved passwords by write or admin user, these passwords are visible as asterisks (********) according to the function. The Fenced user and Instance owner password fields do not allow asterisk symbols. Due to this restriction, during the deployment time you see a validation issue on these two fields.
    Symptom
    When you save the password on the Pattern Builder page and log in as a read-only user, the Fenced user and Instance owner password fields are highlighted in red color. On the Deploy Pattern page, when you click Quick Deploy or Prepare to Deploy without updating the highlighted password fields, the following message is displayed:
    Configuration validation error - One or more parameters have not been specified correctly.
    Resolution
    On the Deploy Pattern page, delete the passwords if they are highlighted in red color. Re-enter the Fenced user and Instance owner passwords and then deploy the pattern.
  • Known issues deployment failure of the pattern for the attached volume.
    Problem
    If the resources in the cloud group are insufficient or if the stuck volume is in unknown state on the storage controller page, the error message Unable to attach volume is displayed in the failed job log of instance.
    Error message
    pooljvm.1733288210558.855 [12-04-24 04:59:46] 0032 pooltask| java.lang.RuntimeException: com.ibm.purescale.iaas.util.exception.IaaSApplicationException: CWZIP1977E The 'Attach Volume' operation has failed.

    If the stuck volume on the Storage_Resources > Luns page is in unknown state, the null pointer exception is displayed in the storage_controller job.

    Error message
    pooljvm.1729083424743.35835 [10-16-24 12:58:58] 0045 pooltask | java.lang.NullPointerException
  • Db2 Fix Packs(Virtual Systems) menu is missing on the CPS after deleting the Db2 Pattern Type
    Problem
    After deleting the Db2 ptype from Pattern development > Pattern Types, Db2 Fix Packs (Virtual Systems) menu is missing.
    Symptom
    After deleting the Db2 ptype, the Db2 Fix Packs menu will disappear. If you go to Pattern development> Fix packs section, the Db2 Fix Packs (Virtual Systems) menu is not visible.
    Resolution

    Upload the deleted Db2 ptype to the CPS, it will fetch the Db2 Fix Packs menu. If Db2 ptype is not in use, keep it in disable state.

    Note: Do not delete the Db2 ptype instead you can disable it.
  • The management node turns off from the IBM Cloud Pak System user interface
    The management node turns off from the IBM Cloud Pak System user interface, which causes the following issues:
    Issue 1: The power status of the Platform System Manager virtual machine shows as Failed.
    When the leader management node is turned off from the IBM Cloud Pak System user interface, it triggers a failover. When the failover completes, the nonleader Platform System Manager virtual machine turns off, and its power status shows as Failed in the IBM Cloud Pak System user interface. To turn on the nonleader Platform System Manager virtual machine, manually power it on from the IBM Cloud Pak System user interface.
    Issue 2: The power status of the Platform System Manager virtual machine and the service console shows as Failed.
    When the nonleader management node is powered off from the IBM Cloud Pak System user interface, the Platform System Manager virtual machine and the service console virtual machine on the management node go to a Failed state. To turn on the Platform System Manager virtual machine and the service console virtual machine on the management node, manually power on the management node from the IBM Cloud Pak System user interface.
  • Users cannot create a virtual machine with the name purevCenter on Virtual System Patterns and Virtual Appliances pages

    Users cannot create or edit a virtual machine by specifying its name as purevCenter. It is a known limitation. This name is reserved. Instead, specify a different name.

  • Job logs are downloaded as .zip files instead of .gz files, which do not get extracted
    Problem
    When you download job logs from the Jobs Queue page of the IBM Cloud Pak System user interface, they download as .zip files and do not get extracted. When the job has large log files, it gets created as multiple .gz files, and all these .gz files are compressed to a single .zip file, which gets downloaded but is not extractable.
    Resolution
    Use the IBM Cloud Pak System command-line interface (CLI) and manually extract the .zip file to view the individual .gz file.
  • Auto scaling and instance deployment

    Before pattern deployment or auto scaling on an instance, IBM® Workload Deployer (IWD) does not validate the status of the compute nodes or availability of resources (storage, CPU, and memory) for both environment profile or cloud group.

    The deployment fails with one of the following error messages in the History log:
    • CWZKS7000E Internal error while placing pattern
    • CWZKS7001E Insufficient storage to place the pattern
    • CWZKS7002E Insufficient memory to place the pattern
    • CWZKS7003E Insufficient CPU resources to place the pattern

    In horizontal auto scaling, though no virtual machine is provisioned in the hypervisor, the virtual machine record appears in the pattern instance page. It happens when the compute node is not in running state or has insufficient resources in the environment profile, cloud group, or compute node.

    As a resolution, ensure that sufficient resources (storage, CPU, and memory) are available in the environment profile, cloud group, or compute node where you deploy the pattern or where the auto scaling is enabled. If problem persists, contact IBM Support.

  • Backup jobs go into a failed state due to the ipas.async blocked jobs
    Problem
    The blocked ipas.async jobs might cause the backup jobs to go into a Failed or Pending state after waiting for a job completion.
    Workaround
    To address this issue, take the blocked job ID from the backup job logs. For example, the job ID can be as follows:
    95bc13db-6125-48ed-93aa-73f394dcf48b
    Then, do these steps:
    1. Run the service purescale status command in the leader Platform System Manager (PSM) and get the process identification number (pid) for the blocked job.
    2. Run the kill -9 <pid> to kill the blocked job.
    3. Run the backup job again after you make the preceding changes.
  • IBM WebSphere® Application Server IHS plugin configuration fails with an error message
    If /bin/bash is not available on AIX, the IBM WebSphere Application Server IHS plugin configuration fails with the following message:
    <message>/opt/IBM/WebSphere/Plugins/config/actionRegistry/actio ns/99SBootStrapPluginsIHS.ant:908:Execute failed: java.io.IOExce "/bin/bash" 
    (in directory "/opt/IBM/WebSphere/Plugins/config/actionRegistry/actions"): error=2, A file or directory in the path name does not exist.

    The fix for this APAR is targeted for inclusion in IBM WebSphere Application Server fix pack 8.5.5.24 and 9.0.5.16. For more information, see Recommended Updates for WebSphere Application Server.

  • Complete restore job fails for the (vCenter Server Appliance Management Interface (VAMI) restore on IBM Cloud Pak System Software for Power®

    As IBM Cloud Pak System Software for Power does not support the File-Based Backup and Restore function of the VMware vCenter Server Appliance, ignore the error for the vCenter Server Appliance Management Interface (VAMI) restore.

    To complete the restore process, use the component level restore and skip the Virtual appliances component. For more information, see Restoring component level data.

  • Virtual machine console is not accessible from the IBM Cloud Pak System user interface
    Problem
    When you log in to the IBM Cloud Pak System user interface and try to access the virtual machine console, it is not accessible and redirects to an error page with the following message:
    Not Found
    The page you have requested has flown the coop.
    Perhaps you are here because:
    
    
    The page has moved
    The page no longer exists
    You were looking for your puppy and got lost
    You like 404 pages
    Go Home
    Workaround
    Log in to the virtual machine by using Secure Shell (SSH) from a terminal window to access the virtual machine console.
  • APAR IT33979 related messages in the 0config logs
    For upgrades that are related to APAR IT33979, the following messages are seen in the 0config logs, which can be ignored:
    • Message 1:

  • IBM OS Image for Red Hat Linux® Systems Red Hat Enterprise Linux (RHEL) 64-Bit Version 8.6 (RHEL 8.6 X64), Version 4.0.1.0 image is not supported in IBM Cloud Pak System
    Problem
    Do not use the IBM OS Image for Red Hat Linux Systems Red Hat Enterprise Linux 64-Bit Version 8.6 (RHEL 8.6 X64), Version 4.0.1.0 image for RHEL 8.6 deployments in IBM Cloud Pak System.
    Workaround
    Instead, use the IBM OS Image for Red Hat Linux Systems Red Hat Enterprise Linux 64-Bit Version 8.6 (RHEL 8.6 X64), Version 4.0.2.0 image for RHEL 8.6 deployments in IBM Cloud Pak System.
  • Users might encounter the “HMC-Hardware problem: (XXXXXXX) Management Console (MC) RMC connection to partition monitoring fault” event
    Problem
    As a user, you might encounter an event as follows:
    “HMC-Hardware problem.: (XXXXXXX) Management Console (MC) RMC connection to partition monitoring fault”

    To determine and troubleshoot whether the problem is with the RMC connection or whether it is a fault alarm that is notified due to momentary failure in RMC connections, you must download the system troubleshooting logs.

    Workaround
    Do these steps:
    1. Log in to the IBM Cloud Pak System user interface.
    2. Go to System > System troubleshooting > Collect system logs > Platform System Manager management (most common) logs.
    3. Download and extract the collected mgmt_node_leader/pvmInfo.txt log file to your system.
    4. Open the file in an editor for edits.
    5. Check for the “LPAR RMC summary: RMC is active on (n of n) Running LPARs” string in the log file, where ‘n’ is the virtual machine (VM) count. For example, see the following log block:
      HMC-1: address: <ipaddress>  version: V8R8.7.0 - Build level 1712090351
         Server-8284-22A-SN7899CEX  state: Operating address: fe80:0000:0000:0000:0a94:efff:fe80:1e91%eth0 fsp_version: 01SV860_138 fsp_exp_date: 05/09/2071
            vios2 state: Running rmc_state: active address <ipaddress> :4d01 version: VIOS 3.1.0.21 (31021P3) HA: BACKUP_SH
            vios1 state: Running rmc_state: active address: <ipaddress> :4561 version: VIOS 3.1.0.21 (31021P3) HA: PRIMARY_SH
            VIOS RMC verificaton test: passed
           LPAR RMC summary: RMC is active on (21 of 21) Running LPARs

      In this example, (21 of 21) indicates that 21 active connections with 21 virtual machines are available, where 21 is the number of virtual machines that are deployed in the HMC. If the count is less that 21, it indicates that a problem exists.

    6. See whether all the RMCs are active or not.
    7. If all RMCs are active, you can ignore the event. If any RMC is missing or is not equivalent to the virtual machine count, contact IBM Support.
  • File exclusion from "Must Gather Logs" script package run: Users can exclude files from "Must Gather Logs" script package run with an external configuration file
    Problem
    A Must Gather Logs script package from the Virtual System Instances page of the IBM Cloud Pak System user interface might fail due to a large /var/log/lastlog sparse file in Red Hat Enterprise Linux (RHEL) virtual machines. For more information, see https://access.redhat.com/articles/3314. With the help of an external configuration file, users can exclude the /var/log/lastlog file.
    Resolution
    If you want to exclude files from the Must Gather Logs script package, create an external configuration file that is called as scriptpackage.cfg in the relevant directory. Add the 'mustgatherexcludefiles' key with comma-separated values of the files that you want to exclude. To exclude the files from the Must Gather Logs script package run, complete these steps:
    1. Create the scriptpackage.cfg file in the relevant directory with the necessary configuration.
    2. Run the Must Gather Logs script package from the Virtual System Instances page of the IBM Cloud Pak System user interface.
    3. If needed, you can also verify the logs.
    Use the following structure of the scriptpackage.cfg configuration file:
    [mustgather]
    mustgatherexcludefiles =
    For example, do these steps:
    1. To exclude the /var/log/lastlog file, create the scriptpackage.cfg file in the /var/log directory with the following entry:
      [mustgather]
      mustgatherexcludefiles = /var/log/lastlog
    2. To exclude the /var/log/lastlog and the /var/log/tallylog files, create the scriptpackage.cfg file in the /var/log directory with the following entry:
      [mustgather]
      mustgatherexcludefiles = /var/log/lastlog, /var/log/tallylog
  • OpenShift Container Platform pattern does not start after shutdown
    Problem
    The OpenShift Container Platform cluster does not start gracefully if the cluster needs to be restarted for some reason such as an OpenShift Container Platform upgrade.
    Workaround
    During restart of the OpenShift Container Platform cluster, ensure that all the OpenShift Container Platform nodes (master, worker, and bootstrap) are started after the primary helper node is started. The OpenShift Container Platform nodes require the DNS or DHCP services to be available during startup, which runs on the primary helper node. Therefore, the primary helper node must be up and running before the OpenShift Container Platform nodes are started.
  • Horizontal Scaling actions might not be available for IBM Control Desk Pattern Type
    Problem
    In IBM Cloud Pak System, Horizontal Scaling actions such as Horizontal Scaling - Add Nodes or Horizontal Scaling - Remove nodes on the Manage > Operations page of the IBM Cloud Pak System user interface might not be available for IBM Control Desk Pattern Type.
    Workaround
    You must redeploy the instance with the requisite number of nodes. Contact IBM Support for assistance.
  • Instance Console page does not start for Windows 2019 deployments
    Problem
    For Windows Server 2019 deployments on IBM Cloud Pak System, the Instance Console (Manage button on pattern instance) page of the IBM Cloud Pak System user interface does not work due to some underlying issues.
    Workaround
    Access the virtual machines directly through a remote desktop application to conduct any management operations such as installing a fix.
  • Menu headers might not be available for deployed instances on Instance Console page
    Problem
    Some of the menu headers such as Instance Console, admin, and other headers might not be available for deployed instances on the Instance Console page of the IBM Cloud Pak System user interface.
    Workaround
    It is a known limitation, which is expected to be fixed in the upcoming release.
  • Shared-Services System-Monitoring External-Service instance upgrade is not supported in IBM Cloud Pak System
    Problem
    The Shared-Services System-Monitoring External-Service instance upgrade fails with the following message:
    Upgrade System Monitoring external mode is not supported.
    Workaround
    Deploy a new version of the Shared-Services System-Monitoring External-Service pattern on IBM Cloud Pak System. For any information, contact IBM Support.
  • Shared-Services System-Monitoring Internal-Service instance upgrade restrictions

    If the target IBM Tivoli® Monitoring shared service pattern includes middleware binary updates, then the instance upgrade would not be complete.

    Problem
    During the IBM Tivoli Monitoring shared service upgrade, the pattern code only gets upgraded and not the middleware binaries. Irrespective of the instance upgrade success, as the middleware binaries are not upgraded the instance upgrade is incomplete.
    Workaround
    You must delete the older IBM Tivoli Monitoring shared service and deploy the new shared service by using the latest IBM Tivoli Monitoring pattern type.
  • MDM 11.6.0.10 pattern deployment with IBM Cloud Pak System fails
    Problem
    During the MDM 11.6.0.10 pattern deployment, the Db2 script fails and states that the mount point /db2inst is not found. However, it is observed from the logs that the mount point gets created from the add-on around few seconds after the Db2 script checks for it.
    Workaround
    Retry the MDM 11.6.0.10 pattern deployment process when you encounter this mount point timing problem.
  • Logging in to the IBM Cloud Pak System user interface displays a service-unavailable message
    The IBM Cloud Pak System user interface and the deployment service menus might not be accessible.
    Problem
    You might see the following message when you log in to the IBM Cloud Pak System user interface despite providing correct user credentials:
    Service unavailable Deployment services are currently down
    Workaround
    Log out and log in to the IBM Cloud Pak System user interface, or log in to the IBM Cloud Pak System user interface from a private window of the web browser.
  • Reports are displayed on the same page when clicked to download using Apple Safari browser
    Reports get downloaded on the same page when you use the Apple Safari web browser.
    Problem
    The downloaded reports are displayed on the same page when you click to download them in the Apple Safari web browser.
    Workaround
    Use the Mozilla Firefox web browser to download the reports.
  • Search on the Virtual System Instance page might not return correct results
    On the Virtual System Instance (VSI) page, a search might not return correct results.
    Problem
    If your search string contains the %20 space encoder, it might not return correct results.
    Workaround
    Do not include your search string with the %20 space encoder to return the expected results.
  • Deployment history shows failure when an update is automatically retried
    When you attempt a deployment upgrade for a virtual system instance, the virtual machines in that deployment restart as part of the upgrade process. Depending on various factors like the type of middleware roles that are deployed on the virtual machine, the upgrade process might take some time to complete. During this process, if any of the virtual machines take longer than 10 minutes to restart, the upgrade is attempted again. This behavior is to ensure that the upgrade request is received by all virtual machines in the virtual system instance, in case it did not happen during the initial attempt for any reason. Due to this delay, the Maestro agent might not be up and running to receive the upgrade request again, and the History section on the Virtual System Instance page shows the following message, which is just an informational message:
    Failed while retrying deployment upgrade for deploymentId: <deployment-id>
    This message does not denote an upgrade failure. The virtual machines might take longer to come up, depending on the type of upgrade. The upgrade process might still complete successfully, however, you can continue to commit or revert the operation according to the normal process.
  • Additional IP addresses cannot be assigned to the virtual machine from the Virtual Machines page

    Additional IP addresses cannot be assigned to the virtual machine from the Virtual Machines page. After a successful deployment of virtual appliance and virtual instance, you cannot successfully assign or configure additional IP addresses to the virtual machine from the Virtual Machines page. If you do so, the IP addresses are seen as assigned on the Virtual Machines page but they fail to assign to the virtual machine.

  • Mapping to wrong network while scaling-out a Virtual System Instance (VSI) in a multi-system environment in IBM Cloud Pak System
    A problem occurs when you map to a wrong network while scaling-out a Virtual System Instance (VSI) in a multi-system environment.
    Problem
    When you scale out a Virtual System Instance (VSI), in a multi-system environment, you cannot map the network cards (NICs) again when multiple NICs are defined in the pattern. This condition might result in NICs that are mapped to the wrong network.
    Resolution
    In a multi-system environment, make sure to deploy at least one virtual machine (VM) on every system during initial deployment. This way, you can define the network card (NIC) mapping, which is used for every additional scaling-out operation. Deploy at least one virtual machine (VM) on every system during initial deployment.
  • Scaling-out a Virtual System Instance (VSI) with scaling policy (hard and anti-colocation) in IBM Cloud Pak System
    A problem occurs when you scale out a Virtual System Instance (VSI) with scaling policy.
    Problem
    Scaling-out a Virtual System Instance (VSI) with scaling policy ("hard" and "anti-colocation") could result in setting the VSI in ‘error’ state with the following message:
    "Can not add the instance to deployment <dep id>, no template found for OS_Node"
    Resolution
    When you use a scaling policy ("hard" and "anti-colocation"), make sure to set the ‘Max’ scaling range based on the number of systems. This change prevents the VSI to move to an ‘error’ state. To recover the instance from this error, contact IBM Support.
  • Scheduled Instance delete (run until) does not work if instance contains virtual machines deployed across systems
    If an instance contains virtual machines that are deployed across systems (multi systems), the Scheduled Instance delete (run until) option does not work.
    Problem
    1. Deploy a pattern in scheduled mode.
    2. Specify the date and time for the deployed instance expiration by using Scheduled Instance delete (run until).
    3. Check whether the instance expires at the specified date and time.

    The deployment is successful. However, the instance expiration encounters an issue such as the local virtual machine shows as Terminated and is not available on the system. The remote virtual machine is listed as Stopped on the Virtual System Instances page and is still available on the remote system. Thus, the instance does not get deleted at the said expiration time.

  • Default configure NIC add-on fails to run successfully on RHEL 7
    On RHEL 7, the Default configure NIC add-on option fails to run successfully during deployment. This problem is observed only in a multi-system environment.
    Problem
    1. Create a pattern with the Default configure NIC add-on option.
    2. Deploy the pattern.

    The instance deployment hangs in Launching state. The problem is with the Default configure NIC add-on. Even if the virtual machine is created and is accessible, the NIC is not configured successfully and hence the failure.

  • Adding more than eight NICs to a virtual pattern fails to configure the NIC
    When you add more than eight NICs to a virtual pattern by using Default add NIC add-on, it fails to configure the NIC on the virtual machine.
    Problem
    1. Create a pattern with the Default add NIC add-on, such that you create a virtual machine with around 10 IP addresses.
    2. Deploy the pattern.

    The virtual pattern is deployed successfully but fails to configure the added NICs. The virtual machine is created with just one IP address.

  • Certain operations like adding or attaching disk volumes to a virtual machine might not be allowed immediately after snapshot deletion
    Even after a snapshot is deleted, adding, or attaching disk volumes to a virtual machine immediately after deletion fails with an error.
    Problem
    Sometimes, an operation such as adding or attaching a disk volume to a virtual machine might not be allowed immediately after snapshot deletion.
    Resolution
    In such cases, wait for few minutes for a clean deletion of the snapshot after which you can retry to attach or add the disk volumes.
  • Disappearing job logs

    Sometimes, few of the job logs might disappear too quickly even before you access them. If the filesystem usage is high or exceeds a certain value (around 80%), then the automatic jobs (an internal job-logs reaping mechanism) get triggered to clean up the logs and free up the disk space.

    Do the following steps as a resolution:
    1. Use the following command to check the usage of /cps-sw-runtime filesystem:

      df -h /cps-sw-runtime
    2. If /cps-sw-runtime is more than 80% full, then check the contents in /cps-sw-runtime/data/storage/images.
    3. Delete the images that are older than a week. The /cps-sw-runtime/data/storage/images is used as a temporary location when images are uploaded so older images can be deleted from this directory to free up space.

    The job logs are preserved after the filesystem usage is lesser than 80%.

  • Creating Multi cloud environment profiles with duplicate name results in an incorrect error message
    When you create Multi cloud environment profiles with a duplicate name, the following error message is displayed instead of the "CWZKS8000 Unable to create the EnvironmentProfiles as it is a duplicate" message:
    “errorMessage”: “Internal Server Error”,
       “rootCause”: “com.ibm.maestro.util.wrapper.exception.MaestroServerException: Internal Server Error”,
       “errorStatusCode”: 500,
       “message”: “Internal Server Error”

    When you see this error, provide alternative names for the Multi cloud environment profile to create a successful Environment Profile.

  • Maximum username length causes issues in granting access through the user interface

    If a username contains more than 64 characters, in such scenarios the Access granted list is not visible in pattern instances or environment profiles. To address this issue, delete the user that has more than 64 characters.

  • Some user interface elements do not show up properly upon navigating between pages

    You might encounter some user interface elements such as labels, menus, etc. that might not show up properly when you navigate between pages.

    To address this issue, either refresh the page or logout and login again.

  • Value assigned in a multi-cloud environment profile

    In a multi-cloud environment profile, set the same value across the systems for IP addresses provided by.

  • Faulty path issues on Platform System Manager (PSM) with RHEV 4.3
    You might encounter faulty path issues on Platform System Manager (PSM) node with RHEL 4.3.
    Problem
    Due to the faulty path issues on Platform System Manager (PSM) with RHEV 4.3, the following issues might occur:
    • Virtual Image or Virtual Appliance upload fails.
    • Compute node upgrade, reinitialization, or upsize failure.
    Diagnosis
    Do these steps to diagnose or check whether faulty paths are the real cause for the issues:
    1. Log on to the leader Platform System Manager (PSM) command-line interface.
    2. Run the following command.
      "multipath -ll"
    3. Verify whether any faulty or failed paths are present in the output.
    4. If you observe any failed paths, the root cause for the failures is due to the faulty paths itself in most of the cases.
    A sample output of faulty paths:

  • Platform System Manager (PSM) node restart might sometimes not work properly
    In some cases, the Platform System Manager (PSM) node might not come online even after you run the restart commands.
    Problem
    When you restart the PSM node by using the psm reboot or the psm reboot remote commands, the node might not come online at times.
    Resolution
    Do these steps to resolve the problem.
    1. Log on to the IBM Cloud Pak System user interface.
    2. Go to Hardware > Management Nodes.
    3. Select the PSM node that you want to restart.
    4. Click Power On that is on the system. If Power On is not enabled, contact IBM Support.
  • License reaper job runs for long hours in System Job Queue

    The license reaper job under System Job Queue might remain in Running state for a day or two. It might also cause issues such as deployment failures, system backup failures, upgrade failures. If you encounter this issue, contact IBM Support for assistance.

  • Pattern deployment fails with Add disk to IBM CloudPak Agent addon

    The pattern that you created with the Add disk to IBM CloudPak Agent addon fails to deploy. Contact IBM Support for assistance.

  • Scheduled pattern deployment with add-ons fails to deploy in a multisystem environment
    Scheduling pattern deployment on a remote system with add-ons in a multisystem environment fails with the following error message.
    Block storage creation or attachment failed. Invalid input: Disk size
    Deploy the pattern instantly rather than scheduling it to avoid this issue.
  • Image creation failure with Linux OS Pattern Kit

    When you create a Red Hat Enterprise Linux (RHEL) image in OVA format with the RHEL ISO file, it results in some known issues. As an alternative, extend the RHEL OS image and customize it according to your requirement. For more information, see Extending and capturing virtual images.

  • Vertical scaling memory selection bar not aligned properly in the Load balancer instance
    The vertical scaling memory selection bar is not aligned properly on the ODR/http node in the load balancer instance, on the Manage instance page.
    Problem
    1. On the Virtual System Instances page, ensure that the load balancer instance is running.
    2. Click Manage and ensure that the instance page is launched.
    3. Go to Operations, select ODR/http node and expand the node.

    The vertical scaling for the memory selection bar is not properly aligned. The bar allows to set only 0 or 100% of memory and nothing in between.

    Resolution
    To scale the memory or to achieve the ODR/http node memory update, do these steps.
    1. Select a load balancer instance from the Virtual System Instances page.
    2. Click Maintain.
    3. Select the ODR/http node and click Edit.
    4. In the Configure the memory and CPU resources of a virtual machine window, specify values for Virtual memory (MB) to scale.
    5. Set the virtual memory value according to your requirement.
      Note: To choose the memory size to scale up, see Vertical scaling.
  • Pattern editing by using Apple Safari browser
    If you modify a read-only mode pattern in an Apple Safari web browser on Mac OS, the browser might hang. Contact IBM Support for assistance, if needed.
    Note: Do not modify a read-only pattern.
  • Service console (https://<PSM/ipas>)

    If you notice issues while you access the Service console with a newly created user, then contact IBM Support.

  • Reports
    • The administration report name is in English for all non-English languages. Though the name of the report is in English language for non-English locale user interface, continue to download the report as the actual contents of the report are in the expected local language.
    • Filtering based on user or users group and date does not work.
  • Attaching block volumes

    When you attach a block volume to a virtual machine from the Virtual Machines page, it sometimes fails and the volume goes into Pending state. If you encounter this failure, contact IBM Support for assistance.

  • Generating Chargeback report
    • If you generate a chargeback report in Microsoft Excel format with more than 256 instances, you might observe an Invalid column Index (256) error. As this behavior is a known limitation in Microsoft Excel, use comma-separated values (CSV) format to generate a chargeback report with more than 256 instances.
  • Multisystem environment

    • If there is a scheduled pattern deployment that deploys on both local and remote systems, then the instance might not show up in the Virtual Instance page of the remote system. However, after the deployment starts, it gets listed in launching state in the Virtual Instance page for both local and remote systems.
    • If a virtual machine of an instance is available in the local system, then its details can be modified by a non-owner who does not have the necessary permissions. If all the virtual machines of an instance are on remote systems, then an update of the instance by a non-owner might fail with the following error:
      CWZKS0413E: Failed to send updateDeployment command for deployment-id. 
      CWZKS7600E: No data available fromrack: Service failed to authenticate 401"

      Before you update, make sure that the user ID has all the permissions on the instance.

    • If an instance has virtual machines both on local and remote systems, then the generated Chargeback report includes details only for the virtual machines in the local system. If all virtual machines of an instance are available in remote systems, then the report does not include any details of that instance.
    • Deployments across different remote systems might encounter errors when the respective deployment is set to maintenance mode.

      This problem occurs when a multi-system deployment has the master node in a different system and you configured it based on the hostname.

      As a resolution, do either of the following options:
      • Set the deployment to maintenance mode from another system.
      • In both the systems (including master), edit the /data/config/hostallowlist.txt file to add the fully qualified domain name of both the systems.
      For any further issues, contact IBM Support.
    • In the Operations tab of the Virtual System Instance > Instance Console page, you might not see the Manual Scaling > Vertical Scaling - Modify memory size option for some virtual machines.
    • The Revert button to revert the changes might be disabled when you update an instance. In such a case, you cannot revert the changes that are made to the instance, but can commit the changes or resume the previously taken snapshot.
    • The Run until deployment option might not work as expected for remote virtual machines. Even if the time reaches the value that is set for Schedule > Run until, the instance does not get deleted. Some of the virtual machines remain in Stopped state while others stay in Terminated state.
    • A virtual machine workload instance gets deployed on a system based on the placement algorithm. However, the password policy check occurs against the password policy that is configured for that specific environment profile in each Platform System Manager (PSM). The specific system where the virtual machine gets deployed is not considered.
    • Loading Environment Profile takes some time

      This issue is due to the synchronization across the systems of a multi-system environment. For example, if a property gets changed in a remote system, you need to refresh the data in other systems of that environment. To achieve that, from each of the systems in the environment, you must have an additional parameter that is sent in the request API as refresh=true. This operation deletes the older storehouse JSON and creates a new JSON with latest values.

    • Environment limits and license gets wrongly applied during deployment
  • Workload management

    If a user does not have Workload resources administration permissions of type View all workload resources (Read-only) or Manage workload resources (Full permission), then the user cannot view the deployed instances of other users even if they grant permissions. The workaround for this issue is to provide the user with read/full permission on Workload resources administration.

  • Backup and restore
    • Environment profile restore operation does not link with cloud groups that are on a remote server
      Problem
      In IBM Cloud Pak System, cloud groups in a multi-system setup might not get attached to an environment profile after a restore operation.
      Workaround
      You must manually attach or link the cloud groups with an environment profile. If you need further assistance, contact IBM Support.
    • Environment profile component restore does not reset original parameter values
      Problem
      Component restore of environment profiles does not reset the individual values of environment profiles parameters to their earlier values when the environment profile component backup was taken.
      Workaround
      You must manually set these values again.
    • Restore from system backup: A manually initiated or scheduled system backup is needed post Platform System Manager (PSM) failover. Each PSM has a unique encryption-related key that must be copied to the backup server host. Hence, it is essential to initiate a full system backup and avoid delta backup after a PSM failover.
      Note: If the full system restore is successful, verify whether the High Availability Status in PSM is online before you attempt operations, for example, pattern deployment.
      If PSM failover occurs, then restore to any backup that was taken after the failover. This action ensures that no encryption-related key mismatch exists and the restore is successful. If you initiate restore after PSM failover without a system backup, then the system restore fails with the following errors.
      • PSM nodes change to Ineligible state.
      • After a few hours, one of the PSM node state changes to 'Non-leader'.
      To restore the PSM and resume online services, contact IBM Support.

      A full system restore job might fail with other network errors even when the metadata files and databases are restored and even after a successful system restart. Determine whether the system is in a healthy state. If not, contact IBM Support.

    • When you back up Pattern Types > Workload component, the job fails with the following error:
      CWZIP1900E An internal error com.ibm.iaas.backup.util.BackupRestoreException: CWZIP9548E Return from GET on patternTypes/itm/1.0.17.0/export?check with status 500: { "errorMessage": "", "rootCause": "com.ibm.maestro.util.wrapper.exception.MaestroServerException: ", "errorStatusCode": 500, "message": "" } occurred. For details, see the log/trace files.
      Do the following workaround to backup successfully:
      1. As a root user, log in to IBM Cloud Pak System command prompt or shell.
      2. Run the following command and check whether its output is 0:
        cat /proc/sys/net/ipv4/tcp_tw_reuse
      3. If the value is 0, run the following command to set it to 1:
        sysctl -w net.ipv4.tcp_tw_reuse=1
    • The full system restore job might fail with other network errors even though the metadata files and databases are restored and the system gets restarted successfully.
      An error message similar to the following sample is available in restore log:
      Exception java.net.NoRouteToHostException: Error opening socket to server /fd8c:215d:178e:c51e:290:fa71:fa05:5cd0 on port 50,002 with message: No route to host (Host unreachable). ERRORCODE=-4499, SQLSTATE=08001 Caused by: No route to host (Host unreachable)

      As a troubleshooting step, check whether the system is in a healthy state. If the system is not healthy, contact IBM Support.
  • Service60 startup
    Sometimes, Service60 goes to FailedOffline state after you run the psm reboot from the leader node. The failure can occur due to variety of reasons. For example, some of them are as follows:
    • Start of IWD (Service60) takes longer than usual.
    • Disk check operation by the OS on the IWD partition during its startup. This delay is expected to vary from time to time and can result in delay of IWD startup.
    • TSA monitors the startup process for every service. If the start of IWD takes longer than usual, TSA tries to stop the service forcefully.
    As a resolution, do the following steps to keep TSA in manual mode while IWD is starting up:
    1. Run the following command to reset Service60 and wait for it to come online.
      psm reset Service60
    2. If IWD fails to come online after the previous step, then run the following steps:
      1. Run the following command to place TSA in manual mode:
        samctrl -M T
      2. Run the following command to reset Service60 and wait for it to come online.
        psm reset Service60
      3. After Service60 comes online, run the following command to place the TSA back to auto mode:
        samctrl -M F
  • Multiple virtual system instances remain in launching state

    If multiple virtual system patterns get deployed at the same time through a script or some automation tool, then some of those instances remain in launching state forever. However, you can access those virtual machines by using SSH.

    As a resolution, contact IBM Support to restart the Service60.

  • Shared service
    • System Monitoring shared service deployment failure
    • Starting or stopping of shared service by non-owner might fail
      Starting or stopping of shared service by non-owner might fail with the following error:
      "CMPRE0001E: An internal server error occurred."
      To resolve, start or stop the shared service instance by using the user who created the instance.
    • In the instance page, the values of System Monitoring Name and Service version varies after the update of Shared Service Instance.
  • Configuring NTP
    • Platform System Manager (PSM) must use Network Time Protocol (NTP) servers to keep system date and time synchronized with an external reference time, and the NTP server time is used as a reference. All components in the system, such as hardware and hypervisors, synchronize their clocks with the system clock to ensure consistency. If the NTP server time is not set, workload instances might consist of deployment errors and the following error is seen in the workload logs:
      ERROR CWZSE0027E: The timestamp in a request falls outside of tolerance range with respect to the local current time

      As a resolution, configure NTP and redeploy the workload instance. For more information, see Configuring date and time settings.

    • Sometimes, Windows deployments fail to launch and the instance is stuck in the "Launching" state. For example, you might see the following error in the logs:
      0config:

      The workaround for this defect is as follows :
      1. Set up the NTP serves. For the actual steps, see Configuring date and time settings.
      2. Raise a PMR and contact IBM Support to rerun 0config script in the virtual machine.
  • Events for Network Switch do not show port details
  • Internal Management Logs collection can fail on NE0152T switch

    The Internal Management Logs collection can fail on NE0152T switch. If failure occurs, contact IBM Support to collect the logs.

  • Locale change in browser

    When you change the browser language after you log in to IBM Cloud Pak System console, the console menu might not render properly and can result in an inconsistent mix of different languages. As a workaround, relogin to the IBM Cloud Pak System console.

    • Password policy
      • After you upgrade IBM Cloud Pak System version and deploy an instance successfully, login to the instance might fail with the following message:
        access denied
        This issue is an inconsistent behavior. As a resolution, if you encounter this issue, redeploy the system instance.
      • The Minimum number of characters for passwords in pattern instance deployment drop-down list is the sum of the minimum number of alphabetic and non-alphabetic characters, and you can select a value in the range 1 - 32. If you select 0 from the drop-down list for Minimum number of alphabetic characters for passwords in pattern instance deployment or Minimum number of non-alphabetic characters in pattern instance deployment, then the specific character type (alphabetic or non-alphabetic) is not considered for the password.
        Note: The "non-alphabetic" characters include both numbers and special characters.
      • When you select an invalid entry, the database is not updated and the following error message is displayed:
        Virtual machine password policy configuration error. 
        The sum of minimum number of non-alphabetic characters in virtual machine password and minimum number of alphabetic characters in virtual machine password must be less than or equal to minimum number of characters in virtual machine password
        Also, the drop-down list values are not updated with the old database values. To resolve this issue, use the refresh icon on the upper right of the page to refresh the environment profiles page.
      • During the environment profile cloning, the password values get reset to default values. This value is 8 for Minimum number of characters for passwords in pattern instance deployment, 1 for Minimum number of alphabetic characters for passwords in pattern instance deployment, and 1 for Minimum number of non-alphabetic characters in virtual machine password.
      • Certain patterns have their own password policy restrictions, for example, the system administrator password field in OpenShift must have a minimum of 32 characters. Db2 password policy must adhere to the minimum Db2 password requirement. In such cases, set the values in the pattern or during deployment such that it obeys the pattern-specific password requirements.
      • The password policy is applicable to the passwords listed in the pattern deployment page.
      • If an administrator user enters ******** during pattern deployment, it bypasses the password policy check.
      • When you deploy a pattern, a stringent password property in a pattern overrides the equivalent password policy rule in the selected environment profile.
      • The behavior is as follows:
        Admin user
        The password policy check is enforced during pattern deployment for pre-saved passwords or if the passwords are entered manually before deployment.
        Non-admin user
        The password policy is enforced during pattern deployment if and only if, the passwords are manually entered before deployment. The password policy check is not enforced for pre-saved passwords. The pre-saved passwords are masked by a default password for security reasons. Therefore, ensure that the pre-saved password conform to the password policy according to the environment profiles that are being used.
        LDAP user
        The preceding aspects apply for admin and non-admin users.
  • Merion switches
    • In the Hardware > Network Devices > Internal Management Switch page, switch commands cannot be run from the user interface. You can still access the information by using switch CLI commands.
    • When you run diagnostics in the Hardware > Network Devices > Internal Management Switch page, the following error message is displayed.
      No Diagnostics (VGEN) MerionNetworkSwitch exists with option..,
      This error does not affect the normal functioning of the switch. Contact IBM Support if you have any functional problems with the switch.
    • The Internal Management Logs collection can fail on the NE0152T switch. If failure occurs, contact IBM Support to collect the logs.
