However, for executing replication function commands in RAID Manager, two device groups must
be combined and defined as a copy group.
When defining a device group or copy group by a command, it can be used from multiple RAID
Manager instances because the group information is defined in the storage system.
Device group definition methods
To define a device group or copy group in the RAID Manager that supports P9500 or later, use
one or both of following methods.
• Execute a command
Create a device group with the raidcom add device_grp command, and execute the raidcom
add copy_grp command specifying the name of the device group to define a copy group.
When the command is executed, a description corresponding to HORCM_LDEV of RAID
Manager is defined in the storage system. Then, define HORCM LDEVG in the configuration
