Checklist and Guidelines for
Booting nPartitions
This section provides both a checklist to use when booting an nPartition,
and a set of guidelines to consider when configuring nPartition boot
settings.
Boot Checklist for nPartitions
Before you boot an nPartition, check the items listed here.
❏ All cells in the nPartition that have a “y” use-on-next-boot value
should be powered on.
If any cells that are set to be used are powered off, the nPartition will
take longer to boot.
During partition rendezvous, the nPartition will wait up to 10
minutes for all cells that are designated to be used. Any cells not
powered on will not be active or available in the nPartition.
❏ All I/O chassis and devices for the nPartition’s active cells should be
powered on.
❏ If any cells that have a “y” use-on-next-boot value are inactive,
perform a reboot for reconfig of the nPartition (shutdown -R) to
allow them to reset and become active during partition rendezvous.
❏ All complex profile information for the nPartition must be coherent.
This means all cells assigned to the nPartition must have identical
complex profile information (Partition Configuration Data).
After you add a cell or remove and active cell from an nPartition, you
must perform a reboot for reconfig of the nPartition (shutdown -R)to
synchronize the complex profile data throughout the nPartition. The
reboot for reconfig also causes all the nPartition’s cells to reboot and
allows cells to go through the partition rendezvous procedure.
Boot Configuration Guidelines for nPartitions
The following guidelines are points to consider when configuring boot
settings for the nPartitions in your server complex.
❏ Configure HAA and ALT boot devices in addition to the PRI device.
