A control volume is used when a server issues control I/O to the relevant disk array. You can select
one logical disk for each disk array as a control volume. Prepare a volume such as IV with which the
server can properly issue I/O to the disk array.
Do not select an RV or a link-volume (LV) for the snapshot function as a control volume because it
may enter the Not Ready state during operation.
