Platform Support Remarks

parconfig is currently not supported on systems with Onboard Administrator (OA) based parti-

tion management.

DESCRIPTION

parconfig is an advisory command. The parconfig

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

par-

create 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

-u 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.

Options and Arguments

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 parti-

tion, 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.

failure_usage ﬁeld is used by system ﬁrmware when a partition is booted. If a CPU

selftest failure or a DIMM deallocation occurs during the power-on self-test process,

then this ﬂag is used by the system ﬁrmware to determine whether or not and how

the cell should be integrated into the partition at boot time. The valid failure_usage

parconfig(1M) parconfig(1M) NAME parconfig - provides a recommended nPartition configuration SYNOPSIS parconfig -O OSname [-X mode] [-Z policy ] [-x] [-p PartitionNumber] [-c cell :[celltype ]:[use_on_next_boot ]:[failure_usage] [:clm_value] ]...
PAGE 2
parconfig(1M) parconfig(1M) values for a cell are: ri float deconf ni reactivate with memory interleave. Specifies to integrate the cell as it would normally be integrated. This is the default for base cells. this is the default value for floating cells. If the user specifies ri for a floating cell, the command displays an error and exits. deconfigure. no interleave. clm_value specifies the amount of the memory that will be configured as local (noninterleaved) memory for the cell.
PAGE 3
parconfig(1M) -n parconfig(1M) At least one of the following -n option must be specified: -n mincpus:N Specifies the minimum number of CPUs to be present in the partition. mincpus keyword indicates that the parconfig command will select cells such that the partition has at least N number of CPUs. N specifies the minimum number of CPUs and does not take into account the CPUs attached to the cell specified through the -c option.
PAGE 4
parconfig(1M) parconfig(1M) in the DEPENDENCIES section are satisfied. -X mode Specifies the mode for configuring the memory of the cell as Cell Local Memory and Interleaved Memory. The valid values for mode are: LORA SMP The memory of the cell is configured as a mix of Cell Local Memory and Interleaved Memory. The exact mix and layout is determined by the -Z option. This is the default. All of the cell’s memory is configured as Interleaved Memory (no clm).

parconfig(1M) parconfig(1M) option) in the recommended configuration of the partition. parconfig -O HPUX_11iV3 -p 0 -c 1:floating:y: -n numcells:5 By default, the core cell of partition 0 will be retained back in the recommended configuration of the partition. Assuming cell located in cabinet 0, slot 0 is core cell of partition 0 and cells located in cabinet 0 at slot 2,3,4,5 are free, the output of the parconfig command will be: parmodify -p 0 -m 0:base:::87.
