HP StorageWorks P9000 Command View Advanced Edition Suite Software 7.1 Administrator Guide (web) (TB581-96050, May 2011)

The following sections describe the requirements for managing copy pairs for each system configuration.
If you have not yet created a copy pair, in the following explanation you must read P-VOL as P-VOL
candidate and S-VOL as S-VOL candidate:
CAUTION:
If you use Remote Web Console (for P9500, XP24000/XP20000, XP12000/XP10000/SVS200, or
XP1024/XP128), SVP, or RAID Manager/LIB, you can create or manage a copy pair without using
RAID Manager. However, a copy pair created by such tools cannot be deleted or its status cannot
be changed from Device Manager unless the storage system is P9500, because there is no configuration
definition file that is controlled by RAID Manager to perform such copy pair operations. If you have
an existing copy pair that was not created using RAID Manager, first release the copy pair (using the
same tool that created it), and then use Device Manager to recreate the volume pairs. You can also
manually create a configuration definition file to control the existing copy pairs.
Local management method
The following figure shows an example of a configuration in which copy pairs are locally managed.
Figure 11 Example of a system configuration for managing copy pairs (local management)
• A host that recognizes the P-VOL or S-VOL must be registered in the Device Manager server.
• The P-VOL or S-VOL is managed by a single Device Manager server.
• From the P-VOL or S-VOL, LUN security must be set for the host.
LUN security from the P-VOL and S-VOL must be set for at least one host, although the host to
which LUN security from the P-VOL is assigned and the host to which LUN security from the S-VOL
is assigned do not need to be the same.
• The host must recognize the P-VOL or S-VOL.
