Types of volumes that are specified as operation targets for data replication commands are as follows:
Table 4-3 shows the list of volume types.

Target System
Type Description Identifier
Windows UNIX
Logical disk name Specifies a logical disk name set on the disk
array side. ld { {
Mount point volume
name
Specifies a mount point volume name assigned
to the volume by the system. mvol { −
NTFS folder name Specifies an NTFS folder name (path name)
for the volume. mdir { −
Drive letter Specifies a drive letter for the volume. drv { −
Special file name Specifies a special file name assigned to the
disk (logical disk) by the system. sfn − {
Volume group name Specifies a name of the LVM’s volume group
that includes the disk (logical disk). vg − {
Disk group name Specifies a name of the VxVM’s disk group
that includes the disk (logical disk). dg − {
{: Targeted −: Not Targeted
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.
