Booting and Shutting Down HP OpenVMS I64
This section presents procedures for booting and shutting down HP OpenVMS I64 on cell-based HP Integrity
servers and procedures for adding HP OpenVMS to the boot options list.
• To determine whether the cell local memory (CLM) configuration is appropriate for HP OpenVMS, refer
to “HP OpenVMS I64 Support for Cell Local Memory” on page 153.
• To add an HP OpenVMS entry to the boot options list, refer to “Adding HP OpenVMS to the Boot Options
List” on page 153.
• To boot HP OpenVMS on a cell-based HP Integrity server, refer to “Booting HP OpenVMS” on page 155.
• To shut down HP OpenVMS, refer to “Shutting Down HP OpenVMS” on page 156.
HP OpenVMS I64 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 OpenVMS I64 does not support using CLM. Before booting OpenVMS on an nPartition, you
must ensure that the CLM parameter for each cell in the nPartition is set to zero (0). Although
you might be able to boot OpenVMS on an nPartition with CLM configured, any memory
configured as cell local is unusable, and such a configuration is untested and unsupported.
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 OpenVMS to the Boot Options List
On HP Integrity servers, you can use the following procedures to manage boot options list entries for HP
OpenVMS.
You can add the \efi\vms\vms_loader.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” on page 141 for additional information about saving, restoring, and creating boot
options.
NOTE OpenVMS I64 installation and upgrade procedures assist you in setting up and validating a
boot option for your system disk. HP recommends that you allow the procedure to do this.
