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

Reconfiguring an nPartition (Integrity)
NOTE: On an Integrity server, the OS kernel in nPars mode needs to write the new CPU
mapping data to certain EFI variables; in order for this to occur properly, a complete reboot in
nPars mode is required after the parmodify operation has taken affect.
From nPars mode:
1. Perform the changes as you would in a non-vPars environment. For example, if we want to
add cell 6 to partition 0:
keira# parmodify -p0 -a 6:base:y:ri
In order to activate any cell that has been newly added,reboot the partition with the -R option.
Command succeeded.
2. Perform a Reboot for Reconfiguration from a virtual partition. For example,
keira# shutdown -R
Do not put the nPartition into vPars mode; you will need to perform an additional reboot
into nPars mode.
3. Allow the system to reboot into nPars mode. Once this is successful, the OS kernel
automatically will write the correct CPU mapping data to EFI. Now you can reboot the
nPartition back into vPars mode and reboot the Monitor.
keira# vparenv -m vPars
keira# shutdown -r
...
fs0:\EFI\HPUX> boot vpmon
...
From vPars mode:
1. Perform the changes as you would in a non-vPars environment. For example, if we want to
add cell 6 to partition 0 for the next boot of the vPars Monitor:
keira1# parmodify -p0 -a 6:base:y:ri
In order to activate any cell that has been newly added,reboot the partition with the -R option.
Command succeeded.
2. Perform a Reboot for Reconfiguration from a virtual partition. For example,
keira1# vparstatus
keira1# shutdown -R -H
At this point, the nPartition is in the Boot-Is-Blocked (BIB) state. Note that once the nPartition
is in the BIB state, vparstatus shows the following message in the remaining virtual
partitions:
Note: A profile change is pending. The hard partition must be rebooted to complete it.
3. Shutdown all the other virtual partitions. For example, on keira2:
keira2# shutdown -h
...
Transition to run-level0 is complete.
Executing "/sbin/reboot-R ".
Note: If this is a partitionable system, the requested reconfiguration will not
take place until all the virtual partitions on this hard partition are shut down
and the virtual partition Monitor is rebooted.
Shutdown at 16:19 (in 0 minutes)
This should bring you to the Monitor prompt (MON>)
4. From the Monitor prompt, boot the nPartition into nPars mode:
MON> reboot nPars
Allow the nPartition to boot into nPars mode. If autoboot is not setup, perform the boot into
nPars mode manually when the system comes up:
