Managing: Performing nPartition Operations
You can perform nPartition operations in a vPars environment, keeping in mind the following:
• If you make an nPartition change where a Reboot for Reconfiguration is required, all the virtual
partitions within the nPartition need to be shutdown and the Monitor rebooted in order for the
reconfiguration to take effect.
• Once the BIB (Boot-Is-Blocked) state is set on the nPartition, virtual partitions will not be able to boot up
until all the virtual partitions have been shutdown and the Monitor rebooted.
For concepts on virtual partitions within nPartitions, see “nPartitions” on page 21.
Examples
For the following examples, the virtual partitions keira1 and keira2 exist within the nPartition 0. Only
relevant output is shown.
Reconfiguring an nPartition
1. Perform the changes as you would in a non-vPars environment. For example, if we want to add cell 6 to
partition 0:
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
.
.
.
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 16:09 (in 0 minutes)
At this point, the nPartition is in the Boot-Is-Blocked (BIB) state. The virtual partition keira1 remains
down until all the virtual partitions have been shutdown and the Monitor rebooted.
Note also that once the nPartition is in the BIB state, vparstatus shows the following message:
Note: A profile change is pending. The hard partition must be rebooted to complete it.
3. Shutdown the other virtual partitions. For example:
keira2# vparstatus
keira2# shutdown -R
