Reassigning (Moving) a Cell
to a Different nPartition
To move a cell from one nPartition to another nPartition in the same
server complex, use the high-level procedure described here.
This high-level procedure involves:
1. Removing (unassigning) the cell from its original nPartition.
2. Performing a reboot for reconfig (shutdown -R) of the original
nPartition, if needed.
3. Adding (assigning) the cell to the new nPartition.
4. Performing a reboot for reconfig (shutdown -R) of the cell’s new
nPartition.
Be aware that this procedure modifies the hardware configurations of
both nPartitions involved.
You should adhere to the hardware requirements and performance
guidelines when removing the cell from its original nPartition and when
adding it to its new nPartition.
When you remove a cell from an nPartition, any I/O connected to the cell
also is removed from the nPartition. As a result, any I/O devices
associated with the cell are made unavailable to the nPartition.
CAUTION Moving a cell that has an attached I/O chassis from one nPartition 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 must be taken in this situation.
For example, LVM volume groups that are being moved from one
nPartition to another must be exported from their original nPartition
before the cell or I/O chassis is moved. For details see the vgexport (1M)
manpage and Managing Systems and Workgroups.
