HP Integrity rx8640, HP 9000 rp8440 Server User Service Guide

To display or set the boot mode for an nPartition on a cell-based HP Integrity server, use any
of the following tools as appropriate. See Installing and Managing HP-UX Virtual Partitions
(vPars), Sixth Edition, for details, examples, and restrictions.
◦ parconfig EFI shell command
The parconfig command is a built-in EFI shell command. See 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. See
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.
See 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 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,
see “HP-UX Support for Cell Local Memory” (page 86).
• To add an HP-UX entry to the nPartition boot options list on an HP Integrity server, see “Adding
HP-UX to the Boot Options List” (page 87).
• To boot HP-UX, see “Booting HP-UX” (page 88).
• To shut down HP-UX, see “Shutting Down HP-UX” (page 95).
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,
see the nPartition Administrator's Guide (http://www.hp.com/go/virtualization-manuals).
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
