Deconfiguring Cells, Processors, and Memory
You can deconfigure (make inactive) a cell that is assigned to an
nPartition by setting its use-on-next-boot value to “n” (do not use). This
causes the cell to remain assigned to the nPartition, but the cell will be
inactive the next time its nPartition boots, meaning the cell’s resources
will not be used.
You also can deconfigure processors and memory from any cell that
is assigned to an nPartition. This causes the deconfigured processors or
memory to not be available for use by the cell or its nPartition.
Whenever you configure or deconfigure cells, processors, or memory, you
must reboot the corresponding nPartition for the configuration change to
take effect.
You can use the following procedures:
• Deconfiguring Cells, Processors, and Memory [BCH] on page 339
This procedure (Configuration menu CELLCONFIG or CPUCONFIG
command, or Service menu DIMMDEALLOC command) configures
and deconfigures cells, processors, and memory using the BCH
interface.
• Deconfiguring Cells, Processors, and Memory [HP-UX] on page 341
This procedure (parmodify -p# -m#::[y|n]:) configures or deconfigures
(makes inactive) cells from the HP-UX command line.
• Deconfiguring Cells, Processors, and Memory [Partition Manager] on
page 342
This procedure (Partition —> Modify Partition menu, Change Cell
Attributes tab) configures and deconfigures (makes inactive) cells
using Partition Manager.
Deconfiguring Cells, Processors, and Memory [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.
