To start the screen for defining a control volume, select [Operation] → [Define Control Volume] from
the Volume List Display screen.
A control volume is a volume used for issuing a control I/O to a disk array from a server. To define a
control volume, prepare a volume beforehand, such as IV which can issue an I/O to a disk array from a
server securely. Do not select RV or a link-volume (LV) of the snapshot function as a control volume,
because they cannot be accessed from a server (OS) while data replication or snapshot is operated.
For a control volume, refer to 4.2.1 “Direct Operation for a Disk Array”.
[Operation Procedure]
(1) To display the Define Control Volume screen, select [Operation] → [Define Control Volume]
from the Volume List Display screen.
