Types of volumes that are specified as operation targets for data replication commands are as follows:

Notes:
1. The identifier is a character string that indicates the volume type and is used in the following
cases:
y When specifying a volume type by a replication operation command option (-mvflg, -rvflg, or
-volflg)
y When specifying a volume type by a pair specification (MV type or RV type) in the replication
operation file
2. To use the volume group, the LVM environment is necessary.
3. To use the disk group, the VxVM environment is necessary.
4. On the UNIX system Solaris version, to specify a special file name (/dev/rdsk/c#t#d#s#), remove
the special file name’s slice (partition) number (s#).
5. The pair setting and unpairing operation (iSMrc_pair command) is performed on a single logical
disk; therefore, it is not possible to specify an LVM volume group or a VxVM disk group.
6. To conduct joint operation with the replication management (controlling the I/O issuance to disk
arrays via the iSM), an applicable volume type is a logical disk name only.
