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 118).

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 118).

To boot HP-UX, refer to “Booting HP-UX” (page 119).

To shut down HP-UX, refer to “Shutting Down HP-UX” (page 127).

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.

To set the CLM configuration, use Partition Manager or the parmodify command. For details, refer to the HP System Partitions Guide or the Partition Manager Web site (http://docs.hp.com/en/ PARMGR2/).

Adding HP-UX to the Boot Options List

This section describes how to add an HP-UX entry to the system boot options list.

You can add the \EFI\HPUX\HPUX.EFI loader to the boot options list from the EFI Shell or EFI Boot Configuration menu (or in some versions of EFI, the Boot Option Maintenance Menu).

See “Boot Options List” (page 114) for additional information about saving, restoring, and creating boot options.
