Managing nPartitions
Unassigning (Removing) Cells from an nPartition
HP System Partitions Guide: Administration for nPartitions, rev 5.1 274
Reboot for Reconfig Guidelines for Removing Cells
In some situations, you must immediately perform a reboot for reconfig
(shutdown -R) of a modified nPartition after removing cells from it.
Performing a required reboot for reconfig completes cell assignment
changes and unlocks the server’s Complex Profile.
•Youmust immediately perform a reboot for reconfig of an nPartition
when you have removed an active cell from the nPartition.
•Youmust immediately perform a reboot for reconfig of an nPartition
when you have removed a cell from an active nPartition and specified
the -B option to the parmodify command.
• You need not perform a reboot for reconfig of an nPartition when you
have removed an inactive cell from an nPartition and did not specify
the -B option to the parmodify command.
In the cases where you must immediately perform a reboot for reconfig
after removing a cell, not doing so will leave the Complex Profile locked
and thus will prevent any other changes to the server complex
configuration. In these cases, the reboot for reconfig is required to
complete the cell assignment changes and permit other changes to occur.
Removing Cells from an nPartition [HP-UX]
This procedure (using the parstatus and parmodify commands)
removes cells from an nPartition using HP-UX commands.
Step 1. List the current nPartition assignments and status for the cells you plan
to remove from their assigned nPartition by issuing the
parstatus -c # ... HP-UX command.
Specify each cell you plan to remove with a separate -c option.
For example, to list details on cells 0, 1, and 2, issue the
parstatus -c0 -c1 -c2 command.
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.
