•Youmust immediately perform a reboot for reconfig of an nPartition
when you have removed an active cell from the partition.
•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 a partition 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.
HP-UX Commands 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 partitions, you must perform this procedure separately for each
nPartition.
In order to remove cells that are not assigned to the local nPartition, the
cells must be inactive (their “Actual Usage” must be “inactive”). You can
list the local partition by issuing the parstatus -w command.
To remove an active cell from its nPartition, you must do so when logged
in to HP-UX running on the cell’s partition.
Step 2. Remove the cell from the partition to which it is assigned by using the
parmodify -p # -d # ... command.
