Installing and Managing HP-UX Virtual Partitions (A.02.01)

Planning Your Virtual Partitions and Installing vPars
Applying a vPars Sub-System Patch
Chapter 494
6. On each virtual partition, repeat Step 3 to install the vPars
sub-system patch on each boot disk of each virtual partition. No
reboot of the virtual partition is required.
Because the boot disk used to boot in standalone mode in Step 2
already has the new vPars patch (this was installed during Step 3),
you can exclude this step for the boot disk at the primary path.
You must install the vPars psatch on each virtual partition before
putting the virtual partitions back into production. Running a mix of
vPars products and versions within a group of virtual partitions is
not supported.
NOTE If you have previously applied any patches specific to vPars, you will need
to re-apply those patches to the vPars product.
