HP-UX Virtual Partitions Administrator's Guide (includes A.03.05 and A.04.05)

Note that in a mixed HP-UX 11i v2/v3 vPars environment, the vPars running A.04.xx must be
running version A.04.02 or later. Therefore, the “Revision” field in the depot should be A.04.02
or greater. Using swlist, we can find the revision number for the vPars A.04.xx bundle on the
depot.

Changing nPartition Boot Paths To Boot the vPars A.05.xx Monitor
To boot a mixed HP-UX 11i v2/v3 vPars environment, you must boot a vPars A.05.xx Monitor.
In our example below, entitled The Update Process, we are updating the first virtual partition (the
virtual partition from which the vPars Monitor is booted) from vPars A.04.01 to A.05.01. However,
if we had chosen to update that partition to only vPars A.04.02, we must change the nPartition’s
PRI (primary) boot path so that it points to the boot disk of a vPars A.05.01 virtual partition,
which would contain a vPars A.05.xx Monitor.
For example, if we originally had this configuration:
nPartition’s PRI boot path is:
boot disk of thurman1
thurman1
vPars A.04.01 with vPars A.04.01 Monitor
thurman2
vPars A.04.01 with vPars A.04.01 Monitor
but wanted to update to the following configuration:
thurman1
vPars A.04.02 with vPars A.04.02 Monitor
thurman2
vPars A.05.01 with vPars A.05.01 Monitor
we must change the nPartition’s PRI boot path to point to the boot disk of a vPars A.05.01 boot
disk, which contains a vPars A.05.01 Monitor, such that
nPartition’s PRI boot path is:
boot disk of thurman2
thurman1
vPars A.04.02 with vPars A.04.02 Monitor
thurman2
vPars A.05.01 with vPars A.05.01 Monitor
Note that to change the nPartition’s PRI boot path, you cannot use setboot from within a virtual
partition; using setboot within a virtual partition changes only the virtual partition’s primary
path entry in the vPars database. Further, you cannot use parmodify from within vPars on
Integrity systems.
However, if you are unfamiliar with the firmware interfaces on PA or Integrity, you can boot
the system into standalone/nPars mode, use parmodify or setboot to change the nPar boot
path, and then boot back into vPars mode. This is included in the steps below.
The Update Process: Goal
In the example below, we begin with three virtual partitions, all running vPars A.04.01:
• the first partition keira1 running vPars A.04.01 (on 11.23)
• the second partition keira2 running vPars A.04.01 (on 11.23)
• the third partition keira3 running vPars A.04.01 (on 11.23)
The first virtual partition is defined as the virtual partition that owns the boot disk from which
the Monitor was booted; you can use the vparstatus -m and vparstatus -v commands to determine
which virtual partition this is.
We wish to update to the following:
• keira1 running A.05.01 (on 11.31)
• keira2 running A.04.02 (on 11.23)
• keira3 running A.05.01 (on 11.31)
The Update Process: Step by Step
The following steps should be done from the console:
