Conﬁguring and Managing Superdome Partitions

Procedures for Managing Partitions

Chapter 4162

Step 1. Plan your partition conﬁguration by selecting which cells will comprise

the new partition.

Use the parstatus -AC command to list all unassigned (available) cells

in your Superdome complex.

You can select any of the cells listed to create the new partition; only the

cells that are not “absent” are eligible to be assigned.

Note that HP recommends only speciﬁc Superdome partition

conﬁgurations.

See “Procedure for Assigning Cells to Partitions” on page 126 for details

on the hardware requirements and related guidelines.

Step 2. After conﬁrming that cells you have chosen would form an HP-supported

partition conﬁguration, create a partition using the cells.

Use the parcreate -c command to create a new partition using the cells

you specify.

Do not specify the -B option, which would immediately boot the newly

created partition, thus making it active and preventing you from further

modifying it.

Note that, because you did not specify -B, the partition will be created

but it will remain “inactive” until you explicitly boot it (using the GSP

command menu’s BO command).
