Windows nPartition Guide v5.5

use The cell use-on-next-boot value: y or n. Use y (the default) if the cell is to be an
active member of the nPartition, or use n if the cell is to remain an inactive
member.
fail The cell failure usage: ri (reactivate with interleave) is the only supported
failure usage policy and it is the default.
For HP Integrity servers, the clm value specifies the amount of memory that will be
configured as cell local memory for the cell.
You can specify the clm value in either of two forms: percentage or absolute amount of
memory.
— Percentage cell-local memory (CLM).
The percent number can be any number in the range 0–100 with a suffix of %.
This number is rounded to 12.5%, 25%, 37.5%, 50%, 62.5%, 75%, 87.5% or 100%. If
the cell contains less than 4 GBytes of memory, then the percentage is rounded to
25%, 50%, 75% or 100%. Percentages are rounded up or down to the nearest value,
but are not rounded up to 100%.
— Absolute CLM specification. (The default.)
The absolute number is interpreted as an absolute number of gigabytes of memory
and can optionally have a suffix of GB.
As needed, an absolute CLM specification is rounded up to the nearest 0.5 GBytes.
If the clm value is rounded, the command reports the final value used.
parmodify command: -B option for nPartition booting You can optionally specify the
parmodify command’s -B option to require that the modified nPartition be rebooted.
• When you specify -B to modify an inactive nPartition, the changes to the inactive
nPartition are completed immediately and the nPartition then boots and becomes active.
• When you specify -B to modify an active nPartition, you must perform a reboot for
reconfig for the changes to be completed. After the reboot for reconfig occurs the
nPartition boots and becomes active (because the parmodify command’s -B option was
specified).
4. As needed, perform a reboot for reconfig on the modified nPartition.
See “Reboot for reconfig guidelines for adding cells” (page 70) for details on when to perform
a reboot for reconfig.
Set core cell choices
The core cell choice settings for an nPartition are optional preferences that establish which cells
in the nPartition are preferred to be selected as the core cell for the nPartition.
NOTE: You do not have to specify core cell choices for a valid core cell to be chosen.
By default on HP Superdome and rx8620/rx8640 servers, system firmware selects the lowest
numbered eligible cell to be the active core cell for the nPartition.
By default on HP rx7620/rx7640 servers, cell 1 is selected as the core cell.
Set the core cell choices for an nPartition using the following procedure:
Procedure 4-33 Setting core cell choices [nPartition commands]
From the command line, use the parmodify command to configure the core cell choices for an
nPartition. You also can use the parstatus -V -p# command to list the core cell choices for
an nPartition (-p# where # is the nPartition number).
