HP-UX Virtual Partitions Administrator Guide (includes A.05.08) (5900-1312, March 2011)

In our example, the first virtual partition keira1 is being updated to vPars A.05.01, so we
would not need to change the nPartition PRI boot path and can proceed to the next step.
However, if keira1 is being updated to only A.04.02, then we would need to change the
nPartition’s PRI boot path to the boot disk of a virtual partition that is being updated to A.05.01.
To do this, perform the following:
a. Find the nPartition partition number for the current nPartition.
keira1# parstatus -w
The local partition number is 0.
The nPartition number is 0. Record this information.
b. Find the boot path of the boot disk of a future vPars A.05.01 virtual partition. This boot
path will become the nPartition’s new PRI boot path.
Since keira3 is being updated to A.05.01, let’s chose to change the nPartition’s PRI path
to the boot disk of keira3.
Since we have chosen keira3 as the future A.05.01 virtual partition, we need to find the
boot path of keira3:
keira1# vparstatus -v -p keira3
...
[IO Details]
0.0.6
0.0.6.0.0.5.0 BOOT
The BOOT attribute identifies the boot path for the virtual partition keira3 as 0.0.6.0.0.5.0.
Record this information.
c. Set the mode for the next nPartition reboot.
• on Integrity, set the mode to nPars for the next reboot: # vparenv -m nPars
• on PA, no mode setting is required.
The remainder of the steps to change the PRI boot path will be done later, while in
nPars/standalone mode.
5. For each virtual partition, except the first virtual partition, use Update-UX to install the latest
OE and vPars bundle. These updates can occur in parallel, although this is not required.
Example where target OS will be 11.31, which implies vPars A.05.xx:
keira3 # update-ux -s depot1:/release/1131/HPUX11i-OE-Ent.DVD HPUX11i-OE-Ent T1335CC
Example where target OS will be 11.23, which implies vPars A.04.xx:
keira2 # update-ux -s depot1:/release/1123/HPUX11i-OE-Ent.DVD HPUX11i-OE-Ent T1335BC
