Reboot for reconfig guidelines for adding cells
In some situations, you must immediately perform a reboot for reconfig of a modified
nPartition after adding cells to it.
• You must perform a reboot for reconfig of an active nPartition after you have added a
cell to it. The reboot for reconfig enables the newly assigned cell to rendezvous and be
actively used when the nPartition reboots.
• Perform a reboot for reconfig of an nPartition as soon as possible after you have added
a cell to an active nPartition and have specified a “y” use-on-next-boot value for the
new cell.
• You need not perform a reboot for reconfig of an nPartition in these situations:
— When you have added a cell to an inactive nPartition.
— When you have added a cell with a “n” use-on-next-boot value and you did not
specify the -B option to the parmodify command.
Add cells to an nPartition using the following procedure:
Adding cells to an nPartition [par commands]
From the command line, use the parmodify command to add cells to an nPartition. You
also can use the parstatus command to list nPartition and complex details, such as
available cells.
Step 1. Use the parstatus -A -C command to list all available cells (the unassigned cells) in
the server complex.
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.
Step 2. Choose one or more eligible cells from the list to add to the nPartition.
Adding the cell(s) to the nPartition must create a configuration that meets the hardware
requirements and performance guidelines.
Step 3. Modify the nPartition by issuing the parmodify -p# -a#... command to add the cell
(-a#... where # is the cell number) to the specified nPartition (-p# where # is the
nPartition number).
To add multiple cells, you can specify the -a option multiple times in the same command.
parmodify command: -a attribute explanation
The parmodify command’s -a... option specifies a cell number and attributes, which
are used when adding the cell to an existing nPartition. An additional cell local memory
attribute is optional.
• For Windows Server 2003, the parmodify command’s -a... option is as follows:
-a cell:[type]:[use]:[fail][:clm]
