• When you specify -B to modify an inactive nPartition, the inactive
partition completes partition rendezvous and becomes active if
possible.
• When you specify -B to modify an active nPartition, you must perform
a reboot for reconfig of the nPartition before any other cell
assignment changes can be made within the server complex.
The parmodify -p1 -a0:base:y:ri -a2:base:y:ri command adds
cell 0 and cell 2 to partition number 1. This command also sets a “y”
use-on-next-boot value for both cells, meaning that they will be active
members of the partition following the next time all cells boot (for
example, when reboot for reconfig is performed on the partition.
Because this example command does not include the -B option, if
partition 1 were an inactive partition it would remain inactive, and if it
were an active partition the new cells would be assigned but they would
remain inactive cells until a reboot for reconfig is performed.
See the parmodify (1M) manpage for details on all options.
Step 4. As needed, perform a reboot for reconfig (shutdown -R) on the modified
partition.
See the Reboot for Reconfig Guidelines on page 214 for details on when to
perform a reboot for reconfig.
Partition Manager This procedure (the Partition —> Modify Partition menu, Add/Remove Cells
tab) adds cells to an nPartition from Partition Manager.
Step 1. Run Partition Manager (/opt/parmgr/bin/parmgr) or access it from
SAM or a Web browser.
Step 2. In the Partition Manager primary window, select the nPartition to which
you want to add cells, then select the Partition —> Modify Partition menu
item.
Step 3. In the Modify Partition window, click the Add/Remove Cells tab.
Step 4. Select the cells that you want to add to the nPartition from the Available
Cells list, then click the Add button to add them to the partition’s cell list.
If adding multiple cells, you can select multiple cells by pressing the
Control key while clicking on the cells.
