Removing Cells from a Partition

Removing a cell involves

1. using a partition conﬁguration tool to designate that the cell be

removed from a partition

2. rebooting the partition for reconﬁguration (performing a

reboot-for-reconﬁg).

Once a cell is removed from a partition, the cell is unassigned and

available for general use, along with any I/O resources connected to the

cell.

Note that, when you remove a cell from a partition, the cell’s I/O chassis

also is removedfrom thepartition. As aresult, any I/Odevices associated

with the cell are made unavailable to the partition.

Also note that at least one cell in each partition must be connected to an

I/O chassis that has a core I/O card installed and an HP-UX boot device

attached.

When removing cells from a partition, you must adhere to the

requirements and guidelines described in “Partition Conﬁguration

Guidelines” on page 125. Hewlett-Packard recommends only a speciﬁc

set of partition conﬁgurations.

You can remove any cell from the local partition, and you can remove any

inactive cell from remote partitions within the same Superdome

complex.

HP-UX Commands This procedure describes how to remove cells from a partition using

HP-UX commands.

Step 1. List the current partition assignments for all cells.

Use the parstatus -C command to list all cells in the complex, and

check the partition assignment for cell that you want to remove.

You can perform this task using HP-UX commands or

Partition Manager.
