Assigning (Adding) Cells to an nPartition

You can add cells to the local nPartition or to any remote nPartitions in

the same server complex.

Adding cells to an nPartition involves selecting available cells (those not

currently assigned to an nPartition) and assigning them to an existing

nPartition. Both the selected cells and any I/O chassis connected to the

cells are assigned to the designated nPartition.

You can add cells to an nPartition by using the following procedures:

• Adding Cells to an nPartition [HP-UX] on page 270

This procedure (using the parstatus and parmodify commands) adds

cells to an nPartition using HP-UX commands.

• Adding Cells to an nPartition [Partition Manager] on page 271

This procedure (the Partition —> Modify Partition menu,

Add/Remove Cells tab) adds cells to an nPartition from Partition

Manager.

When adding cells to an nPartition, you should refer to the guidelines in

the chapter Planning nPartition Conﬁgurations on page 109.

Reboot for Reconﬁg Guidelines for Adding Cells

In some situations, you must immediately perform a reboot for reconﬁg

of a modiﬁed nPartition after adding cells to it.

•Youmust immediately perform a reboot for reconﬁg (shutdown -R)

of an nPartition when you have added a cell to an active nPartition

and you speciﬁed the -B option to the parmodify command.

•Youshould perform a reboot for reconﬁg of an nPartition as soon as

possible after you have added a cell to an active nPartition and have

speciﬁed a “y” use-on-next-boot value for the new cell.

• You need not perform a reboot for reconﬁg of an nPartition in these

situations:

— When you have added a cell to an inactive nPartition.

— When you have added a cell with a “n” use-on-next-boot value

and you did not specify the -B option to the parmodify command.
