If “Activity State” of the RV is “replicate”, it is necessary to separate the RV from the
MV. This is executed here using the settings below. If “Activity State” of the RV is
“separate”, the command below need not be executed.
•
Access restriction for RV after separated: rw (Read/Write) (Default value)
•
Specify wait for separation to complete
> iSMrc_separate -mv mv001 -mvflg ld –rv rv001 –rvflg ld -wait

If “RV Access” of the RV checked in (2) is other than “NA”, stop the volume beforehand

made for logical disk name rv001.

If the target volume is already stopped, the message below is output. Proceed to execute
the procedure in (5).
iSMvss: Err:iSM20519: Specified disk cannot be disabled.
4.
Change the RV data state to invalid and the RV access restriction to Not Available
(NA). Here, settings are made for logical disk name rv001.
