Moving Cells to a Different Partition
To move a cell to a different partition, use the high-level procedure
describe here. This involves:
1. making the cells current partition inactive
2. removing the cell from its current partition
3. adding the cell to the new partition
4. rebooting the cell’s new partition
You must adhere to the requirements and guidelines described in
“Procedure for Assigning Cells to Partitions” on page 126 when moving
cells among partitions. Both the partition from which the cell is removed
and the partition to which the cell is assigned must conform to these
guidelines.
When you remove a cell from a partition, the cell’s I/O chassis also is
removed from the partition. As a result, any I/O devices associated with
the cell are made unavailable to the partition.
CAUTION Moving a cell or I/O chassis from one partition to another is effectively
the same as moving the associated I/O devices from one computer to
another.
All precautions you would take when moving I/O devices from one
computer to another should be taken here. Notably, LVM volume groups
that are being moved from one partition to another need to be exported
from their original partition before the cell or I/O chassis is moved (see
vgexport (1M) and Managing Systems and Workgroups: A Guide for
HP-UX System Administrators)!
Procedure Use the following high-level procedure to move a cell to a different
partition. You can perform these steps using either HP-UX commands or
Partition Manager (parmgr).
Step 1. Use the procedure “Removing Cells from a Partition” on page 181 to
remove the cell(s) that you want to move to the other partition.
