General package notes

Be sure to heed all minimum space requirements before installing.

Review the list of fixes included in Update Release 4.1.1.20

To take full advantage of all the functions available in the VIOS, it may be necessary to be at the latest system firmware level. If a system firmware update is necessary, it is recommended that the firmware be updated before you update the VIOS to Update Release 4.1.1.20.

Microcode or system firmware downloads for Power Systems

If the VIOS being updated has filesets installed from the VIOS Expansion Pack, be sure to update those filesets with the latest VIOS Expansion Pack if updates are available.

Update Release 4.1.1.20 updates your VIOS partition to ioslevel 4.1.1.20. To determine if Update Release 4.1.1.20 is already installed, run the following command from the VIOS command line. 

$ ioslevel

If Update Release 4.1.1.20 is installed, the command output is 4.1.1.20.

Upgrade to VIOS 4.1.x

  • Existing VIOS systems with supported versions of 3.1.x.y can be upgraded to VIOS version 4.1.1.0 (DVD image) or 4.1.1.20 (Flash image) using viosupgrade tool . Although it is recommended to be on VIOS 3.1.4.30 or later SP level before upgrading to VIOS 4.1.x level.

  • VIOS systems with SSP configuration must be on 3.1.3.x or later level before upgrading to 4.1.x level or adding 4.1.x nodes into cluster.

  • If Active Memory Sharing (AMS) is configured on the VIOS, it should be un-configured before upgrading. You may refer the link on how to un-configure.

  • Before upgrading, you may read the viosupgrade blog in PowerVM Community which explains various scenarios.

Note: In an SSP cluster environment, if you're upgrading from version 3.1.4.50 or later, you must upgrade only to version 4.1.1.00 or later. Additionally, ensure that all nodes in the cluster are running version 3.1.4.50 or later before proceeding with the upgrade. 

 

For Customers using NVMe Over Fabric (SAN) as their Boot Disk

Booting from NVMeoF disk may fail if certain fabric errors are returned, hence a boot disk set up with multiple paths is recommended.  In case there is a failure to boot, the boot process may continue if you exit from the SMS menu. Another potential workaround is to discover boot LUNs from the SMS menu and then retry boot.

 

Note

If the Virtual I/O servers are installed on POWER10 systems and configured with “32Gb PCIe4 2-Port FC Adapter, Feature Code(s) EN1J and EN1K”, then the requirement is to update the adapter microcode level to 7710812214105106.070115 before updating the Virtual I/O server to 4.1.1.20 level.

 

Please refer to the release notes at this link

HIPER issue: If you are upgrading to VIOS 3.1.4.50 or 4.1.1.x or above version please consult this link

 

4.1.1.20 New Features

VIOS 4.1.1.20 adds the following new features:

 

viosupgrade enhancements

The major enhancements done in viosupgrade in this release are as follows.

  • viosupgrade will now preserve device names for vfchost/vhost adapter devices, fcnvme, nvme, fscsi, iSCSI devices, network adapters, hdisks etc. by default. A new flag -skipdevname is introduced to skip the above device names preservation.
  • Enables upgrades on systems that have a mirrored rootvg disk.
  • Includes new options, such as the -noprompt flag to answer user prompts in advance in the following scenarios:
    • Prompts you to confirm whether to skip logical volumes that cannot be migrated.
    • Detects third-party Multi Path input output (MPIO) software and prompts you to confirm whether to proceed with the VIOS upgrade.
  • Allows upgrading VIOS by using ISO images in a single step. For example, the -i flag can accept both mksysb and ISO images.
  • Retains user account configurations and the home directories automatically.
  • Supports all the options available in the standalone version of VIOS in the Network Installation Management (NIM) version.
  • Preserves the following security configurations, by default:
    • User accounts and groups with login attributes and password.
    • Role based access control (RBAC) configurations, such as user roles, authorizations, privileged commands database (privcmds), privileged device database (privdevs), privileged files (privfiles) and domains.
    • Login and authentication configurations.
    • AIX audit sub system configurations.
    • Trusted execution policies and databases.
    • IPSec filters and tunnel configurations.
    • Lightweight directory access protocol (LDAP) client configurations.
    • OpenSSL, OpenSSH and Kerberos configurations.

Notes: 

  • Some configurations will be restored from the previous version, while some new configurations are activated on the newer version, and remaining other configurations will be merged from old versions to new versions. Configurations for which both previous and current versions are not used will be saved in the directory /usr/ios/security/saveconf/viosbr folder. You can review the configuration files and manually merge them.
  • These security configurations will be preserved only if you upgrade from VIOS 3.1.4.60.

     

viosbr enhancements

In this release, a new flag -skip is introduced which skips restoration of specified configurations. 

Use “-skip security_config” to skip restore of all the security configurations.

 

VFC enhancements

  • I/O commands timeout improvements in VFC stack on VIOS. It handles starvation conditions for certain higher IO size workloads ( 256K and above ). It  introduces 2 new attributes ( num_local_cmds and bufs_per_cmd ) at VFC host adapter device level on VIOS to manage resources like memory better overall.

 

  • Improve Virtual FC Performance Diagnostics provide support for the VFC client partitions ( "IBM i" in this release of 2024) for collecting I/O response times from the VIOS as a whole subsystem, including the timestamps recorded on different layers in NPIV stack on VIOS and FC adapters.

 

NFS mounted ISO images support in Virtual Media Library

This release adds support for NFS Mounted ISOs in Virtual Media Library which allows to load ISO images from a centralized NFS server, eliminating need for repeated copying of ISO images across multiple VIOS. This saves storage space and time, maintains consistent images, and supports both NFS V3 and V4, allowing multiple images to be linked into the repository. 

The ’mkvopt’ command is enhanced to support new option –nfslink which creates a symbolic link  to the specified NFS ISO file, in the repository. 

$ mkvopt -name <image_name_in_VML_repository> -file /mnt/<mounted_ISO_file.iso> -nfslink -ro

 

Refer the PowerVM Community blog  for details.

 

Remove unwanted language message filesets

The updateios command is extended to support below options to remove unwanted language message filesets. 

  1. -listlang : This option lists all the installed language message filesets.
  2. -rmlang : This option should be used to remove language filesets.
  3. -preserve : This option must be used along with -rmlang to specify the languages to preserve. Rest of the language message filesets will be removed.

     

Shared Storage Pool enhancements

The cluster -status -verbose command is enhanced to display additional storage pool specific information.

The clutil command is introduced with the -o pingcheck option to verify if the network
communication among the SSP cluster nodes are in the working state.

 

Live Partition Mobility (LPM) Validation enhancement for NPIV storage 

Discrepancies in LUN IDs for disks between source and destination hosts can arise from misconfigured LUN masking at the storage level. For instance, the active and inactive WWPNs of a client’s virtual FC adapter may be configured as separate hosts at the storage system, then can assign the same LUNs to these hosts in different orders. This results in varying LUN IDs associated with each WWPN.
Since such configuration can lead to LUN access issues after LPAR migration, the validation algorithms have been enhanced to detect such misconfigurations and report to the user.

 

VIOS 4.1.1.0 has virtual ethernet multi queue feature

This will help to drive more network traffic through virtual ethernet trunk adapter. By default, there will be 12 transmit queues and zero receive queues (legacy receive mode). To increase the bandwidth, one can increase the number of receive queues on virtual ethernet adapter in VIOS by tuning queues_rx attribute of the virtual ethernet adapter. However, using multiple Receive queues to drive more traffic will require more CPU resources.

 

Other enhancements

  1. Enhancement in alt_root_vg command, to run it in phases. This enhancement allows the alt_root_vg command to separate the cloning phase from the update phase.
  2. Enhancement in chdev command, a new option -dynupdate is added to support dynamic updates of supported device attributes. 

 

Hardware Requirements

Please check this link for supported hardware.

Known Capabilities and Limitations

The following requirements and limitations apply to Shared Storage Pool (SSP) features and any associated virtual storage enhancements.

Requirements for Shared Storage Pool

  • System requirements per SSP node:
    • Minimum CPU: 1 CPU of guaranteed entitlement
    • Minimum memory: 4GB
    • Storage requirements per SSP cluster (minimum): 1 fiber-channel attached disk for repository, 10 GB
    • At least 1 fiber-channel attached disk for data, 10GB

 

Limitations for Shared Storage Pool

Software Installation 

  • When installing updates for VIOS Update Release 4.1.1.20 participating in a Shared Storage Pool, the Shared Storage Pool Services must be stopped on the node being upgraded.

*Support for additional VIOS Nodes and LPAR Mappings:

Prerequisites for expanded support:

  • Over 16 VIOS Nodes requires that the SYSTEM (metadata) tier contains only SSD storage.
  • Over 250 Client LPARs per VIOS requires each VIOS have at least 4 CPUs and 8 GB memory.

Here are the new maximum values for each of these configuration options, if the associated hardware specification has been met:

Other notes:

  • Maximum number of physical volumes that can be added to or replaced from a pool at one time: 64
  • The Shared Storage Pool cluster name must be less than 63 characters long.
  • The Shared Storage Pool pool name must be less than 127 characters long.
  • The maximum supported LU size is 4TB, however for high I/O workloads recommendation is to use multiple smaller LUs as it will improve performance. For example, using 16 separate 16GB LUs would yield better performance than a single 256GB LU for applications that perform reads and writes to a variety of storage locations concurrently.
  • The size of the /var drive should be greater than or equal to 3GB to ensure proper logging.


Network Configuration 

  • Uninterrupted network connectivity is required for operation. i.e., the network interface used for Shared Storage Pool configuration must be on a highly reliable network which is not congested.
  • A Shared Storage Pool configuration can use IPV4 or IPV6, but not a combination of both.
  • A Shared Storage Pool configuration should configure the TCP/IP resolver routine for name resolution to resolve host names locally first, and then use the DNS. For step by step instructions, refer to the TCP/IP name resolution documentation in the IBM Knowledge Center.
  • The forward and reverse lookup should resolve to the IP address/hostname that is used for Shared Storage Pool configuration.
  • It is recommended that the VIOSs that are part of the Shared Storage Pool configuration keep their clocks synchronized. 


Storage Configuration 

  • Virtual SCSI devices provisioned from the Shared Storage Pool may drive higher CPU utilization than the classic Virtual SCSI devices.
  • Using SCSI reservations (SCSI Reserve/Release and SCSI-3 Reserve) for fencing physical disks in the Shared Storage pool is not supported.
  • SANCOM will not be supported in a Shared Storage Pool environment.


Shared Storage Pool capabilities and limitations 

  • On the client LPAR Virtual SCSI disk is the only peripheral device type supported by SSP at this time.
  • When creating Virtual SCSI Adapters for VIOS LPARs, the option "Any client partition can connect" is not supported.
  • VIOSs configured for SSP require that Shared Ethernet Adapter(s) (SEA) be setup for Threaded mode (the default mode). SEA in Interrupt Mode is not supported within SSP.
  • Client LPARs are not supported if they use JFS as their filesystem.  If JFS is used, there is a risk of data corruption in the event of a network outage.  JFS2 and other file systems are unaffected by this issue.

VIOS upgrades with Third Party Software

When the user upgrades from 3.1.x.y to 4.1.0.00 level and above, third-party software is not packaged with the IBM supplied mksysb image. User needs to install the respective third-party software after the upgrade is complete and run viosupgrade -o rerun to restore the respective devices.

 

Updating from VIOS version 4.1.0.00

VIOS Update Release 4.1.1.20 may be applied directly to any VIOS at level 4.1.0.00.

Before installing the VIOS Update Release 4.1.1.20

WarningThe update may fail if there is a loaded media repository.

InstructionsChecking for a loaded media repository

To check for a loaded media repository, and then unload it, follow these steps.

  1. To check for loaded images, run the following command:

    $ lsvopt 
    The Media column lists any loaded media.

  2. To unload media images, run the following commands on all Virtual Target Devices that have loaded images.

    $ unloadopt -vtd <file-backed_virtual_optical_device >

  3. To verify that all media are unloaded, run the following command again.

    $ lsvopt 
    The command output should show No Media for all VTDs.

InstructionsMigrate Shared Storage Pool Configuration

The Virtual I/O Server (VIOS) Version 3.1.x.y or later, supports rolling updates to release 4.1.1.20 for SSP clusters.

The rolling updates enhancement allows the user to apply Update Release 4.1.1.20 to the VIOS logical partitions in the cluster individually without causing an outage in the entire cluster. The updated VIOS logical partitions cannot use the new SSP capabilities until all VIOS logical partitions in the cluster are updated.

To upgrade the VIOS logical partitions to use the new SSP capabilities, ensure that the following conditions are met:

  • All VIOS logical partitions must have VIOS Update Release version 3.1.x.y  or later installed.

  • All VIOS logical partitions must be running. If any VIOS logical partition in the cluster is not running, the cluster cannot be upgraded to use the new SSP capabilities.

InstructionsVerify the cluster is running at the same level as your node.

  1. Run the following command:
    $ cluster -status -verbose

  2. Check the Node Upgrade Status field, and you should see one of the following terms:
    UP_LEVEL: This means that the software level of the logical partition is higher than the software level the cluster is running at. 

    ON_LEVEL: This means the software level of the logical partition and the cluster are the same.

 

Installing the Update Release

There is a method to verify the VIOS update files before installation. This process requires access to openssl by the 'padmin' User, which can be accomplished by creating a link.

Instructions: Verifying VIOS update files.

To verify the VIOS update files, follow these steps:

  1. $ oem_setup_env

  2. Create a link to openssl if required
    # ln -s /usr/bin/openssl /usr/ios/utils/openssl 

  3. Verify the link to openssl was created 
    # ls -alL /usr/bin/openssl /usr/ios/utils/openssl 

  4. Verify that both files display similar owner and size 

  5. # exit

Use one of the following methods to install the latest VIOS Service Release. As with all maintenance, you should create a VIOS backup before making changes.

If you are running a Shared Storage Pool configuration, you must follow the steps in Migrate Shared Storage Pool Configuration.

Note: While running 'updateios' in the following steps, you may see accessauth messages, but these messages can safely be ignored.

 

Warning:  If VIOS rules have been deployed. 


During update, there have been occasional issues with VIOS Rules files getting overwritten and/or system settings getting reset to their default values.

To ensure that this doesn’t affect you, we recommend making a backup of the current rules file.  This file is located here: 
/home/padmin/rules/vios_current_rules.xml
First, to capture your current system settings, run this command:
rules -o capture

Then, either copy the file to a backup location, or save off a list of your current rules:

Note: The "padmin" user is restricted to redirect command output to a file, you must be in the root shell. Use "oem_setup_env" to become a root user.

oem_setup_env

# rules -o list > rules_list.txt

After this is complete, proceed to update as normal.  When your update is complete, check your current rules and ensure that they still match what is desired.  If not, either overwrite the original rules file with your backup, or proceed to use the ‘rules -o modify’ and/or ‘rules -o add’ commands to change the rules to match what is in your backup file.

Finally, if you’ve failed to back up your rules, and are not sure what the rules should be, you can deploy the recommended VIOS rules by using the following command:

rules -o deploy -d

Then, if you wish to copy these new VIOS recommended rules to your current rules file, just run:

rules -o capture

Note: This will overwrite any customized rules in the current rules file.
 

Applying Updates

Warning: 

If the target node to be updated is part of a redundant VIOS pair, the VIOS partner node must be fully operational before beginning to update the target node.

Note 1:

For VIOS nodes that are part of an SSP cluster, the partner node must be shown in 'cluster -status ' output as having a cluster status of OK and a pool status of OK. If the target node is updated before its VIOS partner is fully operational, client LPARs may crash.

Note 2:

Updateios command is suggested to run using “-install” option. This option installs new base-level filesets that are shipped along with the existing fileset updates. For example: enabling resize command in VIOS 4.1.1.20 onwards.

Running updateios command with “-install” flag may lead to few fileset update error messages that can be ignored. See below the list of filesets for which the error message can be ignored:

 

X11.apps.msmit 7.3.3.0                    # AIXwindows msmit Application

Warning:

Update to VIOS 4.1.1.20 will update ios.database.rte fileset which might throw below errors, and they can be ignored:

        3001-408  The user "vpgadmin" has an invalid lastupdate attribute.

 

Instructions: Applying updates to a VIOS.

  1. Log in to the VIOS as the user padmin.
  2. If you use one or more File Backed Optical Media Repositories, you need to unload media images before you apply the Update Release. See details here.

  3. If you use Shared Storage Pools, then Shared Storage Pool Services must be stopped.
    $ clstartstop -stop -n <cluster_name > -m <hostname >

  4. To apply updates from a directory on your local hard disk, follow the steps:

    1. Create a directory on the Virtual I/O Server.
      $ mkdir <directory_name >
    2. Using ftp, transfer the update file(s) to the directory you created.
      To apply updates from a remotely mounted file system, and the remote file system is to be mounted read-only, follow the steps:

      1. Mount the remote directory onto the Virtual I/O Server:
        $ mount remote_machine_name:directory /mnt

        The update release can be burned onto a CD by using the ISO image file(s). To apply updates from the CD/DVD drive, follow the steps:                         

                        1. Place the CD-ROM into the drive assigned to VIOS.  

  5. Commit previous updates by running the updateios command:
                    $ updateios -commit

  6. Verify the updates files that were copied. This step can only be performed if the link to openssl was created.
                    $ cp <directory_path >/ck_sum.bff /home/padmin 
                    $ chmod 755 </home/padmin>/ck_sum.bff 
                    $ ck_sum.bff <directory_path > 
                    If there are missing updates or incomplete downloads, an error message is displayed.

                   To see how to create a link to openssl, click here.

  7. Apply the update by running the updateios command  

    $ updateios -accept -install -dev <directory_name >

  8. To load all changes, reboot the VIOS as user padmin . 

    $ shutdown -restart 

    Note: If shutdown –restart command failed, run swrole –PAdmin for padmin to set authorization and establish access to the shutdown                command properly. 

  9. If cluster services were stopped in step 3, restart cluster services.

    $ clstartstop -start -n <cluster_name > -m <hostname >    

  10.  Verify that the update was successful by checking the results of the updateios command and by running the ioslevel command, which should     indicate that the ioslevel is now 4.1.1.20.

      $ ioslevel

              

Post-installation Information and Instructions

Instructions: Checking for an incomplete installation caused by a loaded media repository.

After installing an Update Release, you can use this method to determine if you have encountered the problem of a loaded media library.

Check the Media Repository by running this command: 
$ lsrep

If the command reports: "Unable to retrieve repository data due to incomplete repository structure," then you have likely encountered this problem during the installation. The media images have not been lost and are still present in the file system of the virtual media library.

Running the lsvopt command should show the media images.

 

Instructions: Recovering from an incomplete installation caused by a loaded media repository.

To recover from this type of installation failure, unload any media repository images, and then reinstall the ios.cli.rte package. Follow these steps:

  1. Unload any media images

    $ unloadopt -vtd <file-backed_virtual_optical_device>

  2. Reinstall the ios.cli.rte fileset by running the following commands.

    To escape the restricted shell: 
    $ oem_setup_env 
    To install the failed fileset: 
    # installp –Or –agX ios.cli.rte –d <device/directory > 
     To return to the restricted shell: 
    # exit

  3. Restart the VIOS.

    $ shutdown –restart

  4. Verify that the Media Repository is operational by running this command:

    $ lsrep

- Two versions of postgres database (version 15.6 and 13.14) are included in base image. Postgres version 13 is required to support mixed mode cluster where node versions 3.1.4.x and 4.1.0.x are part of the cluster.

Content removed from 4.1.0.x release and above

ITM Agents software

ITM (IBM Tivoli Monitoring) filesets are not part of VIOS 4.1.0.00 & above versions. Users need to download and install the ITM software from an external location. The ITM VIOS Premium Agent and ITM CEC Base Agent can be downloaded and installed separately as part of an updated IBM Tivoli Monitoring System P Agents 6.22 Fix Pack 4 or later bundle. Here is a link to the readme file containing information about how to obtain the image and instructions for installing.  When these agents are installed in the default directory of /opt/IBM/ITM, they can continue to utilize the cfgsvc, startsvc, and stopsvc commands to configure, start and stop the agent.

AMS

Active Memory Sharing (AMS) feature is removed.
