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-Reconfig (RFR) 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-Reconfig (RFR) 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:
