- parconfig EFI shell command The parconfig command is a built-in EFI shell command. Refer to the help parconfig command for details. - \EFI\HPUX\vparconfig EFI shell command The vparconfig command is delivered in the \EFI\HPUX directory on the EFI system partition of the disk where HP-UX virtual partitions has been installed on a cell-based HP Integrity server. For usage details, enter the vparconfig command with no options. - vparenv HP-UX command On cell-based HP Integrity servers only, the vparenv HP-UX command is installed on HP-UX 11iv2 (B.11.23) systems that have the HP-UX virtual partitions software. Refer to vparenv(1m) for details. NOTE: On HP Integrity servers, nPartitions that do not have the parconfig EFI shell command do not support virtual partitions and are effectively in nPars boot mode. HP recommends that you do not use the parconfig EFI shell command and instead use the \EFI\HPUX\vparconfig EFI shell command to manage the boot mode for nPartitions on cell-based HP Integrity servers. Refer to Installing and Managing HP-UX Virtual Partitions (vPars), Sixth Edition, for details. Booting and Shutting Down HP-UX This section presents procedures for booting and shutting down HP-UX on cell-based HP servers and a procedure for adding HP-UX to the boot options list on HP Integrity servers. • To determine whether the cell local memory (CLM) configuration is appropriate for HP-UX, refer to "HP-UX Support for Cell Local Memory" (page 94). • To add an HP-UX entry to the nPartition boot options list on an HP Integrity server, refer to "Adding HP-UX to the Boot Options List" (page 95). • To boot HP-UX, refer to "Booting HP-UX" (page 96). • To shut down HP-UX, refer to "Shutting Down HP-UX" (page 103). HP-UX Support for Cell Local Memory On servers based on the HP sx2000 chipset, each cell has a cell local memory (CLM) parameter, which determines how firmware interleaves memory residing on the cell. IMPORTANT: HP-UX 11i Version 2 (B.11.23) supports using CLM. The optimal CLM settings for HP-UX B.11.23 depend on the applications and workload the OS is running. To check CLM configuration details from an OS, use Partition Manager or the parstatus command. For example, the parstatus -V -c# command and parstatus -V -p# command report the CLM amount requested and CLM amount allocated for the specified cell (-c#, where # is the cell number) or the specified nPartition (-p#, where # is the nPartition number). For details, refer to the HP System Partitions Guide or the Partition Manager Web site (http://docs.hp.com/en/PARMGR2/). To display CLM configuration details from the EFI Shell on a cell-based HP Integrity server, use the info mem command. If the amount of noninterleaved memory reported is less than 512 MB, then no CLM is configured for any cells in the nPartition (and the indicated amount of noninterleaved memory is used by system firmware). If the info mem command reports more than 512 MB of noninterleaved memory, then use Partition Manager or the parstatus command to confirm the CLM configuration details. 94 Booting and Shutting Down the Operating System

parconfig
EFI shell command
The
parconfig
command is a built-in EFI shell command. Refer to the
help
parconfig
command for details.
—
\EFI\HPUX\vparconfig
EFI shell command
The
vparconfig
command is delivered in the
\EFI\HPUX
directory on the EFI system
partition of the disk where HP-UX virtual partitions has been installed on a cell-based
HP Integrity server. For usage details, enter the

vparenv
HP-UX command
On cell-based HP Integrity servers only, the
vparenv
HP-UX command is installed on
HP-UX 11iv2 (B.11.23) systems that have the HP-UX virtual partitions software. Refer
to
vparenv

NOTE:
On HP Integrity servers, nPartitions that do not have the
parconfig

command do not support virtual partitions and are effectively in nPars boot mode.
HP recommends that you do not use the
parconfig
EFI shell command and instead use
the
\EFI\HPUX\vparconfig
EFI shell command to manage the boot mode for nPartitions
on cell-based HP Integrity servers.
Refer to
Installing and Managing HP-UX Virtual Partitions (vPars)
, Sixth Edition, for details.
Booting and Shutting Down HP-UX
This section presents procedures for booting and shutting down HP-UX on cell-based HP servers
and a procedure for adding HP-UX to the boot options list on HP Integrity servers.
•
To determine whether the cell local memory (CLM) configuration is appropriate for HP-UX,
refer to
“HP-UX Support for Cell Local Memory” (page 94)
.
•
To add an HP-UX entry to the nPartition boot options list on an HP Integrity server, refer
to
“Adding HP-UX to the Boot Options List” (page 95)
.
•
To boot HP-UX, refer to
“Booting HP-UX” (page 96)
.
•
To shut down HP-UX, refer to
“Shutting Down HP-UX” (page 103)
.
HP-UX Support for Cell Local Memory
On servers based on the HP sx2000 chipset, each cell has a cell local memory (CLM) parameter,
which determines how firmware interleaves memory residing on the cell.
IMPORTANT:
HP-UX 11i Version 2 (B.11.23) supports using CLM. The optimal CLM settings
for HP-UX B.11.23 depend on the applications and workload the OS is running.
To check CLM configuration details from an OS, use Partition Manager or the
parstatus
command. For example, the
parstatus -V -c
#
command and
parstatus -V -p
#
command
report the CLM amount requested and CLM amount allocated for the specified cell (
-c
#
, where
#
is the cell number) or the specified nPartition (
-p
#
, where
#
is the nPartition number). For
details, refer to the
HP System Partitions Guide
or the Partition Manager Web site
(
ARMGR2/
).
To display CLM configuration details from the EFI Shell on a cell-based HP Integrity server, use
the
info mem
command. If the amount of noninterleaved memory reported is less than 512 MB,
then no CLM is configured for any cells in the nPartition (and the indicated amount of
noninterleaved memory is used by system firmware). If the
info mem
command reports more
than 512 MB of noninterleaved memory, then use Partition Manager or the
parstatus
command
to confirm the CLM configuration details.
