HP StorageWorks XP Command View Advanced Edition software Device Manager server installation and configuration guide (web version) (T1780-96078, March 2008)

Setup for managing copy pairs
181
• If there are multiple NICs on the host that centrally manages copy pairs, the Device Manager
agent and XP RAID Manager must use the same IP address.
• XP RAID Manager must have fewer than 32 running instances.
CAUTION: When central management is used, copy pairs of a host that uses a platform on which
the Device Manager agent cannot be installed can be recognized.
Table 6-1 shows the copy pair operations and the versions of the Device Manager agent required
for performing the operations.

CAUTION: You can use the Remote Console for XP512/XP48, XP Remote Web Console (for
XP24000/XP20000, XP12000/XP10000/SVS200, and XP1024/XP128), SVP, or XP RAID
Manager library to create or manage a copy pair without using XP RAID Manager. However, you
cannot change the status of or delete such copy pairs from Device Manager, because there is not
a configuration definition file for operating such a copy pair with XP RAID Manager. If you have an
existing copy pair that was not created using XP RAID Manager, first release the copy pair (using
the same tool that created it) then use Device Manager to recreate the volume pairs. You can also
manually create a configuration definition file to control the existing copy pairs.
6-3 Disk array requirements for managing copy
pairs
This section describes the storage subsystem requirements for the operation of copy pairs.
• XP RAID Manager must be installed and enabled.
• After the disk array has been configured as required, the disk array must be refreshed.
• The disk array serial numbers managed by Device Manager must all be unique. In the case of
XP Continuous Access Software, remote disk arrays that are not managed by Device Manager
must also have unique serial numbers.
