This post explains step by step process to update VIO server from one version to new version. VIOS is nothing but Virtual I/O Server. Tested and successfully completed this VIOS update procedure in our environment from VIO 2.2.4.10 to 2.2.6.32 and VIO 2.2.6.10 to 2.2.6.32. Follow the below steps to update the VIO Server.
1. Take the configuration backup and mksysb or alternate disk back.
2. Break the rootvg mirror and take the clone for quick rollback. If your VIO server with single disk take the mksysb backup.
3. Remove the all interim fixes and commit the filesets in current version.
4. Mount the packages downloaded NFS filesystem
5. Update the VIO Server using updateios command and wait until it completed. Next reboot the VIO Server
6. Verify the latest VIOs version and check if any missing packages and re-mirror the rootvg
1. Take the configuration backup and mksysb or alternate disk back.
The viosbr command creates a backup of only the VIOS configuration.
# viosbr -backup -file /tmp/<file name>
Take the mksysb backup for rootvg. It will create entire rootvg backup
# backupios -file <path to NFS location>/<file name> -mksysb
2. Break the rootvg mirror and take the clone for quick rollback. If your VIO server with single disk take the mksysb backup.
To break the rootvg mirror and create a clone for quick rollback
$ bootlist -mode normal –ls
$ unmirrorios hdisk1
# migratepv hdisk1 hdisk0 (Run as root user)
$ reducevg -rmlv rootvg hdisk1
$ alt_root_vg -target hdisk1
$oem_setup_env (to get root shell)
# bosboot -ad hdisk0 (using root shell)
# bootlist -m normal hdisk0 hdisk1 (using root shell)
3. Remove the all interim fixes and commit the filesets in current version.
To remove all interim fixes, if any installed.
$ lssw
$ updateios -remove <ifix_LABEL>
Commit existing filesets:
$ updateios –commit
4. Mount the packages downloaded NFS filesystem
# mount $nim_server:/nim/$location_of_vios_patches /mnt
# cd /mnt
5. Update the VIO Server using updateios command and wait until it completed. Next reboot the VIO Server
Run the following command to perform updating VIOS.
$ updateios -accept -install -dev /mnt -> it will install the VIOS patches
Upon successful update completion take a reboot of server .
$ shutdown -restart
6. Verify the latest VIOs version and check if any missing packages and re-mirror the rootvg
Check consistency of currently installed filesets
# instfix –i | grep ML
# lppchk –v
$ ioslevel
Once everything confirmed, re-mirror the rootvg.
$ extendvg rootvg hdisk1
$ mirrorios hdisk1
$ bootlist -mode normal -ls (to view)
$ oem_setup_env (to get root shell)
# bosboot -ad hdisk1 (using root shell)
# bootlist -m normal hdisk0 hdisk1 (using root shell)
# exit (using root shell, to go back to VIOS shell from root shell)
VIOS Backout/Rollback Procedure :
Change the bootlist and Reboot the server with older version.
#bootlist –m normal hdisk1 hdisk0
#bootlist –m normal –o
#shutdown –Fr now
Once the server is came up, Re-mirror the rootvg .
$ extendvg rootvg hdisk1
$ mirrorios hdisk1
$ bootlist -mode normal -ls (to view)
$ oem_setup_env (to get root shell)
# bosboot -ad hdisk1 (using root shell)
# bootlist -m normal hdisk0 hdisk1 (using root shell)
# exit (using root shell, to go back to VIOS shell from root shell
