For Separate, the iSMrc_separate command is used.
The iSMrc_separate command separates RV from MV and makes RV available from the system.
MV and RV must be set as a pair.
[Main Options]
For iSMrc_separate command, you can specify the following options regarding the Separate operation.
(1) Specifying paired volumes
Specify MV and RV volumes.
y Specify MV (-mv volume -mvflg mv_flg)
Specifies the volume and volume type of MV.
y Specify RV (-rv volume -rvflg rv_flg)
Specifies the volume and volume type of RV.
For information about volume types, refer to 4.3 “Volume Types”.
On the Windows system, when a specific partition (drive letter) is specified for a volume
consisting of multiple partitions, all partitions in the volume become operation targets; therefore,
the default setting does not allow the multiple partitions to be operated. To perform operations
for a volume consisting of multiple partitions, you need to change the default setting. For
information about the replication operation option setting file, refer to the “Data Replication
Command Reference”.
(2) Specifying the access restrictions to RV after Separate(-rvacc)
You can specify the access restrictions to RV after Separate.
y Read/Write (-rvacc rw)
Reference and update can be performed for RV.
y Read Only (-rvacc ro)
Only reference can be performed for RV.
Pay careful attention when you specify Ready Only (-rvacc ro) for the RV access restrictions.
For details, refer to 2.6 “RV Access Restriction”.
(3) Specifying the wait for Separate completion(-wait /-nowait)
The system can wait for the command end after Separate until Separate is complete.
y Wait Specified (-wait [second])
If a value is specified in second, the monitoring time interval of the disk array becomes the
specified value. The available range is from 1 through 30 seconds (integer). If the value is
omitted, the RPL_WATCHDEV setting in the replication operation option setting file is used
for Windows while the setting of environment variable RPL_WATCHDEV is used for UNIX.
For details on operational settings, refer to the “Data Replication Command Reference”.
