Moving I/O to a Different 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)!
You have the following options for moving I/O from one partition to
another.
• Moving a single I/O card to different partition.
If you just need to move a single I/O card, you can move the card from
the I/O chassis in which it currently is installed to an I/O chassis that
is available in the partition where you want it to reside.
This is essentially the same as moving an I/O card from one system to
another.
• Moving an I/O chassis to a different partition.
If you need to move an entire I/O chassis from one partition to
another, you can use either of the following methods.
— Connect the I/O chassis cables to a cell in the partition.
Only HP service personnel should perform this task. Contact HP to
have the I/O chassis cables connected to a different cell.
For details see “Moving an I/O Chassis to a Different Cell” on
page 200
— Assign the cell to which the I/O chassis is connected to belong to a
different partition.
Reconfigure the complex so that the cell to which the I/O chassis is
connected is assigned the partition in which you want the I/O to be
available.
