PACKAGE: Update Release 4.1.2.00
IOSLEVEL: 4.1.2.00

VIOS level is

The AIX level of the NIM Master level must be equal to or higher than

Update Release 4.1.2.00

AIX 7300-04

General package notes

Be sure to heed all minimum space requirements before installing.

Review the list of fixes included in Update Release 4.1.2.00

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 4.1.2.00.

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 4.1.2.00 updates your VIOS partition to ioslevel 4.1.2.00. To determine if Update Release 4.1.2.00 is already installed, run the following command from the VIOS command line.

$ ioslevel

If Update Release 4.1.2.00 is installed, the command output is 4.1.2.00.

Upgrade to VIOS 4.1.x

  • Existing VIOS systems with supported versions of 3.1.x.y can be upgraded to VIOS version 4.1.2.00 (DVD image) or 4.1.2.00 (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 1: 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. 

Note 2: When upgrading a VIOS from version 4.1.1.00 or later to 4.1.2.00 using the viosupgrade method you may encounter a boot issue while booting with the new rootvg disk, if it gets into incorrect combination of attributes reserve_policy and algorithm. Run below command on the SCSI disks to avoid the problem.

$ chdev -dev hdiskX -attr reserve_policy=single_path algorithm=fail_over

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 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 7710812214105106.070120 before updating the Virtual I/O server to 4.1.2.00 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

4.1.2.00 New Features

This release of VIOS contains several enhancements in PowerVM virtualization area.

 

Live Partition Mobility (LPM) enhancements

You can bypass the port-level validation for the N_Port ID Virtualization (NPIV) devices for logical partition (lpar) migration with Linux or IBM i operating systems. This action successfully completes the LPM operation if all the Logical Unit Numbers (LUN) are available across both the source and destination VIOS instances, irrespective of the storage ports through which they are accessible.

For more information, see Specifying the attributes for a partition mobility operation by using the VIOS.

 

VIOS command enhancements

The following enhancements are made to the commands:

  • The fcstat command displays the I/O latency statistics across multiple layers like Storage Area Network (SAN) and fiber channel adapter. For virtual AIX® clients, you can also view additional statistics for VIOS, hypervisor and client Virtual Fibre Channel (VFC) adapter layers.

  • The updateios command uses alternate disks to install new updates and retain the current state of the rootvg disk. When you run the updateios command, the current rootvg disks are cloned to the alternate disks and perform the new installation process. You can use the -altdisk option to provide values of one or more alternate disks, separated by a colon.

  • The following AIX commands can be accessed in VIOS through the Role Based Access Control (RBAC) security functionality:

  • The viosecure command permits or denies firewall rules for an entire subnet range along with the IP address.

  • The lsmap command filters NPIV device mappings based on the partition name and operating system type. Use the -cpname and -cpos options along with the -npiv option to display the relevant device mappings.

  • The RBAC- enabled AIX pvi command in VIOS lets you view and modify restricted system configuration files, such as /etc/syslog.conf through the following steps:

  • Run the setsecattr command to add vios.file.read or vios.file.write authorizations to the required system configuration file.

    Example:

                setsecattr -f writeauths=vios.file.write /etc/cronlog.conf

    • Run the setkst command to apply the authorization changes to the system configuration file.

    • Run the pvi command to access and edit the system configuration file.

 

Virtual Fibre Channel (VFC) adapter enhancements

The following enhancements are made to the VFC adapters:

  • The Quality of Service (QoS) feature in VIOS is a technological preview for the VFC stack. It enables you to manage and prioritize storage traffic between a virtual machine (VM) and a Fibre Channel (FC) storage area network (SAN) by setting performance limits on VFC host adapters.

  • During critical events, VIOS automatically sends notifications to client lpars so that the lpars can take action on these critical events. This rectification action reduces the disruption or delay in the I/O processing activity if other unaffected VFC paths are available. These critical events may occur due to the following disruptive operations:

    • Firmware (microcode) updates

    • Extended Enhanced Error Handling (EEH) events

    • Live dump operations

For more information, see the latest AIX and IBM i documentation.

 

Shared Storage Pool (SSP) enhancements

The following enhancements are made to the shared storage pool:

  • When the VIOS nodes in an SSP cluster is upgraded to VIOS version 4.1.2.00 or later, the Node Upgrade Status of the nodes changes to the UP_LEVEL state. After all the nodes are upgraded to the 4.1.2.00 level, the rolling upgrade process starts automatically and the Node Upgrade Status level changes to the ON_LEVEL state.

  • Log recording is enabled for the SSP- related commands on the VIOS command line interface (CLI).

 

Shared Ethernet Adapter (SEA) accounting enhancements

The SEA accounting functionality monitors the network traffic to and from the client virtual Ethernet adapters it serves. Enhancements have been made in the functionality to reduce the overhead in SEA accounting. This improves the overall SEA performance.

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 4.1.2.00 participating in a Shared Storage Pool, the Shared Storage Pool Services must be stopped on the node being upgraded.

SSP Configuration 

FeatureMin Max
Number of VIOS Nodes in Cluster16*
Number of Physical Disks in Pool1024
Number of Virtual Disks (LUs) Mappings in Pool8192
Number of Client LPARs per VIOS node250*
Capacity of Physical Disks in Pool10GB 16TB
Storage Capacity of Storage Pool10GB 512TB
Capacity of a Virtual Disk (LU) in Pool1GB 4TB
Number of Repository Disks1
Capacity of Repository Disk10GB 1016GB
Number of Client LPARs per Cluster2000

 

*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:

FeatureDefault Max High Spec Max
Number of VIOS Nodes in Cluster1624
Number of Client LPARs per VIOS node250400

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 4.1.2.00 may be applied directly to any VIOS at level 4.1.0.00.

Before installing the VIOS Update Release 4.1.2.00

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 4.1.2.00 for SSP clusters.

The rolling updates enhancement allows the user to apply Update Release 4.1.2.00 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 4.1.2.00 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

  8. To load all changes, reboot the VIOS as user padmin .
  9. If cluster services were stopped in step 3, restart cluster services.
  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 4.1.2.00.

$ shutdown -restart

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

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

$ ioslevel

  1. Please run below command to remove unwanted software

updateios -remove_outdated_filesets

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
