HP-UX Virtual Partitions Administrator Guide (includes A.05.09) (5900-2188, March 2012)

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 84).
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.
TIP: The parmodify command requires major path components to be separated with a
slash (/). For example, 0.0.6.0.0.5.0 would be specified as 0/0/6/0/0.5.0 when using
parmodify.
7. Install the latest and OS-applicable Update-UX bundle onto each virtual partition that will be
updating the HP-UX Operating Environment—including all virtual partitions updating to HP-UX
11i v2 and vPars A.04.05.
This does not update the operating system, only the Update-UX bundle.
Use Ctrl-A to switch between consoles.
