parconfig Command
The parconfig command provides a recommended nPartition configuration.
Refer to the parconfig(1M) manpage for complete details.
Synopsis
parconfig -O OSname [-X mode] [-Z policy][-x] [-p
PartitionNumber][cell:[celltype]:[use_on_next_boot]:[failure_usage]
[:clm_value] ]...{ -n mincpus:N | -n minmem:N | -n mincpus:N -n minmem:N |-n numcells:N }
[ [-u username[:] -h IPaddress|hostname ] | [-g -h IPaddress|hostname ] ]
The parconfig is an advisory command. The command runs a set of the Locality-Optimized
Resource Alignment (LORA) rules and provides recommended configuration of the nPartition.
See lora(7) for information about Locality-Optimized Resource Alignment. By default parconfig
gives advice in the form of a parcreate command for the new local partition and the advice
is displayed on the standard output. The -p option can be specified to get advice in the form of
a parmodify command for an existing partition. Either the -u or -g option can be specified
to get the advice for the specified target (local or remote) complex. The resulting advice in the
form of parcreate or parmodify command can be redirected to a text file; the user can then
modify the command if needed and explicitly execute the command to create new recommended
nPartition or to modify an existing nPartition. Superuser permission is required to run this
command on the local partition. If the -u or -g option is used to access a remote partition or
complex; superuser permission is not required on the local system, and the local system need
not exist on an nPartition. If the-g option is specified, username on the remote host must have
superuser permission or the command will fail. Please refer to the nPartition Administrator’s Guide
for a description of the partition management terms used in this man page.
The -u and -g options are mutually exclusive.
Options
parconfig recognizes the following command line options and arguments:
-c cell:[celltype]:,
[use_on_next_boot]:[failure_usage][:clm_value]
Identifies a cell to be assigned to the partition. To assign
multiple cells to the partition, multiple -c options should
be used.
cell specifies the cell ID. It can be specified either in the
local (cabinet#/slot#) or global (cell#) format. For example,
the cell located in cabinet 0, slot 1 is identified in the local
format as 0/1 or in the global format as 1.
celltype specifies the type of the cell. The valid
celltype values for a cell are:
base A base cell in a partition participates in interleaved
memory.
floating A floating cell in a partition does not
participate in interleaved memory (all of the
cell’s memory is used as CLM).
NOTE: If no celltype is specified, policy rules (specified
through the -Z option) will be applied to the cell to
determine the type of the cell.
use_on_next_boot specifies whether the cell will
participate in a reboot. The valid values for
use_on_next_boot are:
y Participate in reboot. This is the default. However if
the slot is missing or the cell does not exist or the cell
is powered off then it defaults to n.
n Do not participate in reboot.
