HP StorageWorks Disk Array XP RAID Manager: User’s Guide

HORCM_CMD section

Description

The HORCM_CMD section defines the RM command devices RM uses to
communicate with the disk array. A RM command is initiated to write
command data to the special disk array command device. The disk array
then reads this data and carries out the appropriate actions.

Multiple command devices are defined in this section of the configuration
file to provide alternate command devices and paths in the event of failure.

It is recommended that each host have a unique command device. A
command device should not be accessed by more than one host. Multiple
instances on the same host can use the same command device.

To configure command devices, use Command View XP, LUN
Configuration Manager, Remote Web Console XP or Command View XP
Advanced Edition. If none of these are available, ask your HP
representative to configure the command devices.

Syntax

HORCM_CMD

command_device [ command_device ] . . .

Examples

HP-UX

HORCM_CMD

/dev/rdsk/c2t3d0 /dev/rdsk/c6t2d4

This example defines two device files as paths to a command device. These
devices can be pvlinks to the same volume on the disk array, or may be
different command devices. Placing the second command device on the
same line implies that it is an alternate within the same array.
