Deconfiguring Cells, Processors, and Memory
You can deconfigure (make inactive) a cell that is assigned to a
partition by setting its use-on-next-boot value to “n” (do not use). This
causes the cell to remain assigned to the partition, but the cell will be
inactive the next time its partition boots, meaning the cell’s resources
will not be used.
You also can deconfigure processors and memory from any cell that
is assigned to a partition. This causes the deconfigured processors or
memory to not be available for use by the cell or its partition.
Whenever you configure or deconfigure cells, processors, or memory, you
must reboot the corresponding partition for the configuration change to
take effect.
You can perform these procedures using the following methods:
• BCH on page 281
This procedure (Configuration menu CELLCONFIG or CPUCONFIG
command, or Service menu DIMMDEALLOC command) configures
and deconfigures cells, processors, and memory using the BCH
interface.
• HP-UX on page 283
This procedure (parmodify -p# -m#::[y|n]:) configures or deconfigures
(makes inactive) cells from the HP-UX command line.
• Partition Manager on page 284
This procedure (Partition —> Modify Partition menu, Change Cell
Attributes tab) configures and deconfigures (makes inactive) cells
using Partition Manager.
BCH This procedure (Configuration menu CELLCONFIG or CPUCONFIG
command, or Service menu DIMMDEALLOC command) configures and
deconfigures cells, processors, and memory using the BCH interface.
Step 1. Access the BCH interface for the partition whose cells, processors, or
memory you want to configure or deconfigure.
