General package notes

Be sure to heed all minimum space requirements before installing.

Review the list of fixes included in Update Release 4.1.2.10

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 4.1.2.10.

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 4.1.2.10 updates your VIOS partition to ioslevel 4.1.2.10. To determine if Update Release 4.1.2.10 is already installed, run the following command from the VIOS command line.

$ ioslevel

If Update Release 4.1.2.10 is installed, the command output is 4.1.2.10.

Upgrade to VIOS 4.1.x

·      Existing VIOS systems with supported versions of 3.1.x.y can be upgraded to VIOS version 4.1.2.10 (DVD image) or 4.1.2.10 (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: Using updateios command, vios can be updated from 4.1.1.00 or later to 4.1.2.10 level. However, if you use upgrade method using viosupgrade command, 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 4.1.2.10 level.

4.1.2.10 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:

 

1.  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

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

3.  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:

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:

 

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.

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

 

Before installing the VIOS Update Release 4.1.2.10

 

Warning: The update may fail if there is a loaded media repository.

 

Instructions: Checking 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.



Instructions: Migrate Shared Storage Pool Configuration

 

The Virtual I/O Server (VIOS) Version 3.1.x.y or later, supports rolling updates to release 4.1.2.10 for SSP clusters.

 

The rolling updates enhancement allows the user to apply Update Release 4.1.2.10 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.

Instructions: Verify 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 4.1.2.10 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 4.1.2.10 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.

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

  2. 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.

  3. Apply the update by running the updateios command
    $
     updateios -accept -install -dev <directory_name >

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

$ shutdown -restart

 

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

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

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

  1. 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 4.1.2.10.

$ 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

 

Content modified in this release

Software Updated

·      The filesets that contain the PostgreSQL13 and PostgreSQL15 versions are available in VIOS.

o   The PostgreSQL15 version is updated to the PostgreSQL15.12 version

o   The PostgreSQL13 version is updated to the PostgreSQL13.20 version

·      You must add the -install option while you run the updateios command to install the following PostgreSQL filesets:

o   ios.viodb13.rte

o   ios.viodb15.rte

·      If you don’t have SSP or SSP doesn’t have 4.1.0.00 prior versions nodes, then you may remove ios.viodb13.rte fileset.

o   Once the ios.viodb13 is removed, the node can never be added back to SSP with prior version nodes.

·      The Bind.rte fileset is added to the VIOS expansion pack

 

 

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.

Removal of Legacy Font Families

Starting with Virtual I/O Server (VIOS) 4.1.2.10, IBM has discontinued support for the following legacy font families and removed all their variants:

·      Courier (including Symbol variants)

·      Helvetica (including Symbol variants)

·      Times New Roman (including Symbol variants)

·      WorldType (including Chinese variants)

These fonts were previously standard components in the VIOS Font Collection, but will no longer be included with the VIOS.
The impact of font removal depends on the installation method (VIOS updates vs. fresh installation):

·       Updating existing VIOS to VIOS 4.1.2.10: existing legacy fonts will be preserved during the update process.

·       Fresh installations: for fresh installation of VIOS 4.1.2.10 (or later), legacy fonts will not be available.
