Windows nPartition Guide v5.5

• You must immediately perform a reboot for reconfig of an nPartition when you have removed
an active cell from the nPartition.
• You must 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.
You can remove cells from an nPartition by using the following procedure:
Procedure 4-37 Removing cells from an nPartition [nPartition commands]
From the command line, use the parmodify command to remove cells from an nPartition. You
also can use the parstatus command to list current nPartition details such as cell assignments.
1. Log in to the Windows system.
NOTE: You must include the correct remote administration options when issuing par
commands (-h and -g for IPMI over LAN connections; -h and -u for WBEM/WMI
connections). For a complete explanation of these options, see the command description in
“nPartition Commands Reference” (page 89).
If using remote administration features to modify an nPartition, you can log in to any
Windows system.
If removing an active cell from an nPartition and not using remote administration features,
you must log in to the nPartition from which the cell is to be removed.
2. Issue the parstatus -c#... command to list the current nPartition assignments and
status for each cell (-c# where # is the cell number) that you plan to remove from its assigned
nPartition.
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 if you want 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.
3. Remove the cell from the nPartition to which it is assigned by using the parmodify -p#
-d#... command.
Specify the nPartition (-p# where # is the nPartition number) and each cell (-d# where # is
the cell number) that you want to remove from the nPartition.
If you are performing this task using a Windows system to remotely administer a server,
also specify the -u... -h... options or the -g... -h... options as appropriate.
If removing multiple cells from an nPartition, specify each cell with a separate -d# option
on the same command line (such as: parmodify -p1 -d0 -d2... to remove cells 0 and
2 from partition number 1).
Slightly different procedures are required for removing active cells and inactive cells. See
the following information for details.
