Notes:
(1) The identifier is a character string that indicates the volume type and is used in the following cases:
When specifying a volume type by a replication operation command argument (-mvflg, -rvflg, or
-volflg)
When specifying a volume type by the 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 canceling operation (iSMrc_pair command) is performed on a single logical disk;
therefore, it is not possible to specify a LVM volume group or a VxVM disk group.
(6) To operate together with the replication management (controlling the issuance of I/O to disk arrays via
the NEC Storage Manager), an applicable volume type is a logical disk name only.
