HP-UX Virtual Partitions Administrator Guide (includes A.05.07) (5900-1229, September 2010)

4. If gWLM is in use, disable (undeploy) gWLM’s management of resources in all virtual
partitions.
gWLM is supported with restrictions in mixed HP-UX 11i v1/v2 vPars environments, as of
the first release of vPars A.03.05 and vPars A.04.05. For details on gWLM restrictions, see
“Features of Mixed HP-UX 11i v1/v2 vPars Environments” (page 58).
For details on how to disable gWLM, see Getting Started with HP Integrity Essentials Global
Workload Manager and reference the “Stop Managing an SRD” (shared resource domain)
procedure.
5. Determine if you need to change the PRI boot path and record the necessary boot path
details.
If the current nPartition’s PRI boot path currently points to a virtual partition that will be
updated to only A.03.05 and not A.04.05, you will need to change the nPartition’s PRI boot
path such that it points to the boot disk of a virtual partition that will be updated to A.04.05.
For more information, see “Changing nPartition Boot Paths To Boot the vPars A.04.xx
Monitor” (page 90).
In this example, the first virtual partition azure1 is being updated to vPars A.04.05, so we
would not need to change the nPartition PRI boot path and can proceed to the next step.
However, if azure1 were being updated to only A.03.05, 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
vPars A.04.05.
To record the necessary boot path details, perform the following steps:
a. Find and record the nPartition number for the current nPartition.
Use the parstatus -w command from any virtual partition.
azure1# parstatus -w
The local partition number is 0.
In this example, the nPartition number is 0. Record this information.
b. Find the boot path of the boot disk of a future vPars A.04.05 virtual partition. This boot
path will become the nPartition’s new PRI boot path.
Use the vparstatus -v -p vparname command from any virtual partition.
In the following example, we find the boot path of azure3, which is being updated to
vPars A.04.05 and thus could serve as the first virtual partition (the one that owns the
boot disk from which the vPars Monitor is booted).
azure1# vparstatus -v -p azure3
...
[IO Details]
0.0.6
0.0.6.0.0.5.0 BOOT
The BOOT attribute identifies the boot path for the virtual partition azure3 as
0.0.6.0.0.5.0. Record this information.
The next step changes the PRI boot path for the nPartition.
6. If you need to change the PRI boot path for the nPartition, follow the procedure below.
Otherwise, proceed to the next step.
The nPartition’s PRI boot path must point to the boot disk of a vPars A.04.05 virtual partition.
Use the parmodify command from HP-UX running on any of the virtual partitions in the
nPartition to change the nPartition PRI boot path.
parmodify -p partitionNumber -b priPath
where partitionNumber is the nPartition number recorded earlier, and priPath is the
boot path, selected earlier, of a virtual partition that will have vPars A.04.05 installed.
