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

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.
CAUTION:
Note the following if using Device Manager to manage a copy pair that was created by using a
management tool other than Device Manager:
• When the copy pair is created by using Remote Web Console, SVP, or RAID Manager LIB,
You need to perform either of the following:
- Manually create a configuration definition file to define the copy pair.
- Dissolve the copy pair by using the management tool that was used when creating the copy pair,
and then create a copy pair by using Device Manager.
• When the copy pair is a Fast Snap copy pair defined in a copy group
If you manage copy pairs of 65 generations or more from the Device Manager GUI, delete the
existing copy group, and then create a copy pair by using a snapshot group.
If you manage the copy pair from the Device Manager CLI, dissolve the copy pair by using the
management tool that was used when creating the copy pair, and then create a copy pair from
the Device Manager CLI.
CAUTION:
The requirements for defining or managing copy pairs by using a virtual volume on P9500 are as
shown below:
• 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.
- Specify the physical ID for Serial# of the HORCM_LDEV parameter.
- For the HORCM_CMD parameter, specify the command devices whose storage system resource
group ID is 0 (meta_resource).
• User authentication must be completed after enabling authentication mode for command devices
and executing the raidcom -login command for all command devices whose storage system
resource group ID is 0 (meta_resource). If the OS of the pair management server is Windows,
user authentication must be completed as the user who executes the Device Manager agent service
(HBsA Service).
