In this example, we will use the VIOS VML to apply SP2 to an AIX 7.2 TL1 SP1 system. This procedure assumes that the LPAR and the VIOS are both on the same Power System.
1. On any AIX 7.x system (or any OS that can create ISO images of files). Create a directory containing AIX 7.2 TL1 SP2 update filesets. Create a toc file in that directory. Create another empty directory where the ISO image will be stored (ensure it has enough space to hold the image file).
[root@750lpar4]/export/nim/lpp_source # mkdir aix72tl1_sp2_only
[root@750lpar4]/export/nim/lpp_source # cd aix72tl1_sp2_only
[root@750lpar4]/export/nim/lpp_source/aix72tl1_sp2_only # inutoc .

[root@750lpar4]/ # ls -ltr /export/mksysb/cg/aix72tl1_sp2_only_ISO
total 0
2. Use the mkdvd command to create an ISO image of the directory. The ISO file will be created in this location. In the example below the ISO file is named cd_image_27984148 during creation. On AIX, you can check the integrity of the ISO file by mounting it with the loopmount command and view the contents.
[root@750lpar4]/ # mkdvd -r /export/nim/lpp_source/aix72tl1_sp2_only -S -I /export/mksysb/cg/aix72tl1_sp2_only_ISO

3. Login to the VIOS (padmin) and copy (scp) the ISO file to the VIOS media library. Ensure there is enough free disk space for the ISO image file.

4. Rename the image file to something more meaningful. Change the permissions to read only for the owner.
# mv cd_image_27984148 AIX7.2TL1SP2update_only
# chmod 400 AIX7.2TL1SP2update_only
# ls -ltr AIX7.2TL1SP2update_only
-r-------- 1 root staff 1840168960 Jul 24 12:36 AIX7.2TL1SP2update_only
5. Verify the ISO appears in the lsrep output on the VIOS.
# exit

6. To update an LPAR using the image file in the library, assign a virtual optical device and load the ISO image to the LPAR. In this example, vhost36 is one of the VSCSI adapters assigned to the LPAR that is to be updated. A new virtual optical device will be created. Load the ISO image into this vopt device (vopt5 in this example).
On the AIX LPAR:
root@cgaix / # echo cvai | kdb -script | grep vio
vscsi0 0x000007 0x0000000000 0x0 750vio1->vhost37
vscsi1 0x000007 0x0000000000 0x0 750vio1->vhost36
On the VIOS:
$ mkvdev -fbo -vadapter vhost36
vtopt5 Available
$ loadopt -disk AIX7.2TL1SP2update_only -vtd vtopt5
$ lsrep | grep only
AIX7.2TL1SP2update_only 1755 vtopt5 ro
7. On the LPAR to be updated, configure the virtual cdrom device (cd0).
root@cgaix / # lsdev -Cc cdrom
root@cgaix / #
root@cgaix / # cfgmgr
root@cgaix / # lsdev -Cc cdrom
cd0 Available Virtual SCSI Optical Served by VIO Server
8. Apply SP2 on the LPAR using the virtual CD device (cd0).

9. Once the update is completed successfully, you can remove the cd0 device from the LPAR and the vtopt device on the VIOS. Or, if you plan on performing more updates, you can choose to leave the devices in place. However, this will prevent you from using LPM, should you need to, in the future; at which time you would need to remove the devices before migrating them to another frame. You can also remove the ISO image file from the VIOS VML when you're done using it, if you wish.
On the AIX LPAR:
root@cgaix / # rmdev -dl cd0
cd0 deleted
On the VIOS:
$ rmdev -dev vtopt5
