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

In the next step, the entire nPartition will be rebooted; if the other virtual partitions are still
in progress of updating, the OS instances may be in an unknown state.
NOTE: If the BOOT and ALTBOOT disks are a mirrored pair, updating is not required on
the ALTBOOT disk. Otherwise, if you wish to have the alternate boot disk updated, after
updating the OS on the primary boot path disk, boot the virtual partitions from the alternate
path boot disk and repeat the update-ux procedure. For example, if keira2 has an alternate
boot disk that is not a mirror of the primary boot disk, and you wish to update the OS on
the alternate boot disk, boot keira2 from the alternate boot path using:
MON> vparload -p keira2 -B ALT
and repeat the update-ux procedure:
keira2# update-ux -s depot1:/release/1123/HPUX11i-OE-Ent.DVD HPUX11i-OE-Ent T1335BC
7. Reboot the nPartition. Example:
MON> reboot
On Integrity, if you need to change the PRI boot path, reboot in nPars mode:
MON> reboot npars
NOTE: At this point, you need to reboot the nPartition from the MON> prompt, not just
the virtual partition. By rebooting the nPartition, you can load the new vPars Monitor.
8. If you need to change the PRI boot path, follow the procedure below. Otherwise, proceed to
the next step.
a. Interrupt the boot up process and enter into standalone (PA) or nPars (Integrity)
mode: Example for PA-RISC:
BCH> bo pri
interact with IPL: y
ISL> hpux /stand/vmunix
Example for Integrity:
Shell> fs0:
fs0:\> hpux
HPUX> boot vmunix
b. Change the nPartition’s PRI path to the boot path of the future A.05.01 partition recorded
earlier. Example:
keira# parmodify -p0 -b 0.0.6.0.0.5.0
where the syntax of parmodify is
• -p nPartition_number
• -b primary_boot_path
c. Verify the new PRI path using parstatus:
keira# parstatus -p0 -V
[Partition]
Partition Number : 0
Partition Name : npar0
Status : active
IP address : 0.0.0.0
PrimaryBoot Path : 0/0/6/0/0.5.0
...
d. Once the PRI path has been successfully changed, set the mode to back to vPars:
