replication operation is executed for a volume made up of multiple partitions or logical
volumes or for a dynamic disk volume. The table below shows the function range for each

Initial Setup of Volumes
Backup Server Connected to Snapshot Logical Volume (LV)
When performing backup operations in which the snapshot function is used, the initial
setup below is necessary. Execute identical operations for target volumes used in backup
operations. The volume states, which are the states in which “Installation Procedure” in the
“Snapshot User’s Manual (Installation and Operation Guide for Windows) ended, are
assumed to be “active” for the SV state and “unlink” for the LV link state.
1.
Start a command prompt on the backup server.
2.
Confirm that volumes used in backup operations have been registered in the volume
list created in (Installation and Operation Guide for Windows)” and re-create the
volume list.
> iSMvollist -a
3.
In order to change the LV access restriction to Not Available (NA), stop the volume
beforehand.
Here, the setting is made for logical disk name lv001.
> iSMvss -devmode disable -vol lv001 -volflg ld
4.
Change the LV access restriction to Not Available (NA). Here, settings are made for
logical disk names lv001 and sv001.
> iSMsc_link -lv lv001 -lvflg ld -sv sv001 -svflg ld -lvacc na
> iSMsc_unlink -lv lv001 -lvflg ld
The above is the end of environment setup for operation using the snapshot function.
