• NOTE: Configuring and deconfiguring cells may be restricted based on any Instant
Capacity contract for the server complex.
To make an inactive cell active (configured), its use-on-next-boot value must be "y"
and its nPartition must perform a reboot for reconfig (shutdown -R). To make an
active cell inactive (deconfigured) its use-on-next-boot value must be "n" and its
nPartition must perform a normal reboot (shutdown -r).
• BCH Menu: Configuration Menu, CELLCONFIG command.
• EFI Shell: cellconfig command; use of this command is restricted.
• nPartition Commands: parmodify -p# -m#... command to modify attributes of
the specified cell (-m#..., where # is the cell number) for the specified nPartition (-p#,
where # is the nPartition number).
— Original nPartition Commands — For the cell modify (-m) option, specify:
-m#::y: to configure the cell to be used the next time the nPartition boots, or
-m#::n: to deconfigure the cell.
— Enhanced nPartition Commands — For the cell modify (-m) option, specify:
-m#::y::clm to configure the cell to be used the next time the nPartition boots, or
-m#::n::clm to deconfigure the cell. The clm parameter specifies the amount of
cell local memory.
• Partition Manager:
— Version 1.0 — Select the nPartition to which the cell belongs, select the
Partition→Modify Partition action, Change Cell Attributes tab, select the cell(s),
and click Modify Cell(s).
— Version 2.0 — Select the nPartition to which the cell belongs, select the
nPartition→Modify nPartition action, Set Cell Options tab, and configure the
use-on-next-boot value.

• NOTE: Configuring and deconfiguring processors may be restricted based on any
Instant Capacity contract for the server complex.
After a processor configuration is changed the nPartition in which the processor resides
must be rebooted to use the new configuration.
• BCH Menu: Configuration Menu, CPUCONFIG command.
CPUCONFIG cell cpu OFF deconfigures the specified processor (cpu) on the specified
cell (cell).
CPUCONFIG cell cpu ON configures the processor on the cell.
• EFI Shell: cpuconfig command.
cpuconfig cell cpu off deconfigures the specified processor (cpu) on the specified
cell (cell).
cpuconfig cell cpu on configures the processor on the cell.
See “Configuring and Deconfiguring Processors” (page 217).
