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:

1. Make sure that all the virtual partitions are up. You can check this with vparstatus.
