HP P9000 Command View Advanced Edition Suite Software 7.3.1-00 Administrator Guide (web)

Table Of Contents
In this configuration, copy pairs are directly managed by using an SVP as a virtual command
device instead of managed by using a storage system physical command device. You do not need
to prepare a command device for the storage system. This configuration is supported only when
both the P-VOL and S-VOL exist in P9500.
There are two types of configurations: configurations in which copy pairs are defined and managed
by using a configuration definition file, and configurations in which copy pairs are defined and
managed as a device group
NOTE:
If copy pairs are managed in a configuration that uses an SVP (the out-of-band method), the
processing time of Replication Manager might increase because the command response time of
RAID Manager tends to increase, compared to when copy pairs are managed in a configuration
that uses a physical command device (the in-band method).
In SVP configurations, you can use the GUI to check the configuration of and change the pair
status of copy pairs defined as device groups.
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.
System configuration for managing copy pairs: Local management
The following figure shows an example of a configuration in which copy pairs are locally managed.
