HP XP7 Command View Advanced Edition Administrator Guide (Web Version) (TK981-96004, May 2014)

CAUTION:
The requirements for defining or managing copy pairs by using a volume in a virtual storage machine
on HP XP7 are as shown below:
• If you want to operate virtual volumes by using physical IDs, copy pairs must be configured in
such a way that they are managed with the central management method.
• The configuration definition file must be recreated to match the new environment after migration.
- For Serial#, devNum, and portName of the HORCM_LDEV parameter, you can specify either
a virtual ID or a physical ID.
- For the HORCM_CMD parameter, specify the command devices whose storage system resource
group ID is 0 (resource pools of the default virtual storage machine).
System configuration for using the local management method to manage copy pairs
Set up the management server, hosts (application servers), and storage system so that the prerequisites
are satisfied.
