Managing nPartitions
Unassigning (Removing) Cells from an nPartition
HP System Partitions Guide: Administration for nPartitions, rev 5.1 277
The cells must all be assigned to the same nPartition in order to remove
them using a single procedure. Otherwise, if the cells are assigned to
different nPartitions, you must perform this procedure separately for
each nPartition.
Step 2. Run Partition Manager (/opt/parmgr/bin/parmgr) or access it from
SAM or a Web browser.
Step 3. In the Partition Manager primary window, select the nPartition from
which you want to remove cells, then select the Partition —> Modify
Partition
action.
Step 4. In the Modify Partition window, click the Add/Remove Cells tab.
Step 5. From the “Cells in the Partition” list, select the cells that you want to
remove from the nPartition. Then click the Remove button to move them
to the Available Cells list. If removing multiple cells, you can select
multiple cells by pressing the Control key while clicking on the cells.
Removing the cell(s) from the nPartition should create a configuration
that adheres to the hardware requirements and performance guidelines.
Step 6. After you have removed the cells from the nPartition’s cell list, click the
OK button.
The cells are not actually removed from the nPartition until after the
next step.
Step 7. Review the information shown in the Notes and Warnings, the Summary of
Changes
, and the HA Checks tabs.
Partition Manager generates this information when it checks details of
the new nPartition configuration.
If you must perform a reboot for reconfig of the nPartition, such as when
removing an active cell from the nPartition, then the Notes and
Warnings tab provides details and options.
• If a reboot for reconfig is required, the Notes and Warnings tab has
information about the reboot procedure. (See Step 9 for details.)
