HP StorageWorks P9000 Virtualization Adapter Administrator Guide (5697-0680, October 2010)

RAID Manager and array configurations
HORCM instances
To use the P9000 Virtualization Adapter, HORCM instances X are needed on both sites (primary and
secondary), but remote communications are not needed between the instances. However, if Continuous
Access paired volumes are created using RAID Manager, remote communications are needed. For
failover testing, HORCM instance X+1 is needed. If HORCM X is not running, the P9000 Virtualization
Adapter uses the auto option (-auto) to start it. The P9000 Virtualization Adapter then tries to start
HORCM X+1. Figure 3 shows the RAID Manager configuration for the P9000 Virtualization Adapter.

Fibre Channel Address conversion table
Because VMware ESX Server uses WWN and LUN number notation for device discovery, the Fibre
conversion table number for HORCM must be changed using $HORCMFCTBL variable:
C:\HORCM\etc> set HORCMFCTBL=3
C:\HORCM\etc> horcmstart
This variable is set to 3 automatically by the P9000 Virtualization Adapter, but if the auto option
(-auto) is used, then the LUN number in horcm.conf must be specified as the same LUN number
on ESX Server, P9000 Remote Web Console, or XP Remote Web Console.
