Using Other Tools for Managing nPartitions Cell-level tasks 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, refer to the command description in "nPartition Commands Reference" on page 109. NOTE Unassign (remove) cells from an nPartition Removing a cell from an nPartition involves unassigning the cell from the nPartition to which it is assigned and, if necessary, performing a reboot for reconfig of the nPartition. Adding or removing cells from an nPartition will change the amount of memory available to the nPartition, possibly significantly. You should consider how the memory change may affect the amount of swap space necessary for the nPartition and if needed adjust the swap space size. When not using remote administration features, you can remove any cell from the local nPartition and can remove inactive cells from remote nPartitions in the same server complex. However, at least one core-capable cell must remain in each nPartition. The remote administration features supported by Windows nPartition tools also enable you to remove any cell from any nPartition in an HP Integrity server complex. Still, at least one core-capable cell must remain in each nPartition. Reboot for reconfig guidelines for removing cells In some situations, you must immediately perform a reboot for reconfig of a modified nPartition after removing cells from it. Performing a required reboot for reconfig completes cell assignment changes and unlocks the Complex Profile for the server. • 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: Removing cells from an nPartition [par 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. Step 1. Login to the Windows system. Chapter 4 93

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, refer to the command description in “nPartition
Commands Reference” on page 109.
Unassign (remove) cells from an nPartition
Removing a cell from an nPartition involves unassigning the cell from the nPartition to
which it is assigned and, if necessary, performing a reboot for reconfig of the nPartition.
NOTE
Adding or removing cells from an nPartition will change the amount of memory available
to the nPartition, possibly significantly. You should consider how the memory change
may affect the amount of swap space necessary for the nPartition and if needed adjust
the swap space size.
When not using remote administration features, you can remove any cell from the local
nPartition and can remove inactive cells from remote nPartitions in the same server
complex. However, at least one core-capable cell must remain in each nPartition.
The remote administration features supported by Windows nPartition tools also enable
you to remove any cell from any nPartition in an HP Integrity server complex. Still, at
least one core-capable cell must remain in each nPartition.
Reboot for reconfig guidelines for removing cells
In some situations, you must immediately perform a reboot for reconfig of a modified
nPartition after removing cells from it. Performing a required reboot for reconfig
completes cell assignment changes and unlocks the Complex Profile for the server.
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:
Removing cells from an nPartition [par commands]
From the command line, use the

nPartition. You also can use the
