Chapter 4 Functions of NEC Storage ReplicationControl SQL Option
Unless well versed in OS and file system operations for Windows, Read Only (-rvacc ro) should
not be specified for the RV access restriction. For details, refer to 3.6 "RV Access Restrictions
Setting" of the "NEC Storage Manager Data Replication User's Manual (Installation and
Operation Guide for Windows)".
(5) Specifying waiting for snapshot backup completion (-wait/-nowait)
With snapshot backup, the program can be made to wait for the end of the command after
executing the separation.
Wait specified (-wait [second]): When the value is specified to "second", the disk array's
No wait (-nowait):
(6) Canceling the MV/RV state check (-nocheck)
Performs snapshot backup without checking the MV/RV state.
Normally, the snapshot backup command is not operated unless synchronization between MV and
RV is completed. Specifying "-nocheck" makes it possible to perform snapshot backup even when
MV-RV synchronization is not completed.
This is specified when the MV-RV synchronization time is unclear but immediate backup is
necessary.
(7) Specifying the time when the RV becomes available (-rvuse)
The snapshot backup function makes it possible to specify the time at which the RV becomes
available after separation has been performed. This specification is applicable when performing
a snapshot backup without checking the state of the MV/RV.
Normal separation (-rvuse complete):
Immediate separation (-rvuse immediate):
monitoring time interval becomes the specified time. The
specifiable value is 1 to 30 seconds (integer number). When
the value is omitted, 5 seconds is set.
The command is ended only after specifying snapshot
backup start. It is not made to wait for separation
completion.
The end of separation is checked by the iSMrc_query
command.
Allows the RV to be used after separation has
been performed and the differential reflection
(synchronization) of the MV and the RV has
been completed.
Makes the immediate use of the RV possible
while the differential reflection
(synchronization) of the MV and the RV is being
performed after separation has been performed.
