new SnapOPC+ copy session.
The procedure to start the SnapOPC+ session is as follows:
Procedure

REC multiplicity setting
Set the multiplicity used for performing REC. This setting is required when the connection
type in the [Set Copy Path] is "Remote".
Refer to
"8.2.14 Modify REC Multiplicity" (page
Copy session creation
Note that GUI can only create the SnapOPC+ sessions that are performed in volume units.
To create other copy sessions, use the copy management software. Refer to
SnapOPC+" (page
199).
Copy session check
Check the status of each copy session using the [Advanced Copy Status] screen.
Refer to
"8.1.1 Advanced Copy (Basic Information)" (page
For REC sessions, checking copy path and buffer status are also available.
Refer to
"8.1.4.2 Copy Path" (page 185)
•
Only SnapOPC+ copy sessions that are performed in units of volumes
can be created using GUI.
To create EC sessions, OPC sessions, QuickOPC sessions, SnapOPC
sessions, SnapOPC+ sessions using range selection, and REC
sessions, use copy management software.
•
When using SnapOPC+, SDVs are required as copy destination vol-
umes. The "Capacity of source volume" that is specified when creating
SDVs indicates the copy source Standard volume capacity.
When creating an SDV using the [Create Volume] function, the capacity
setting is not required. 24 (MB) + 0.1% of the copy source volume
capacity is automatically secured in the ETERNUS DX Disk storage
system. "24MB" is the smallest volume capacity. 0.1% of the copy
source volume is the capacity that is used for the controlling information
area in the SDV. When using SnapOPC or SnapOPC+, make sure to
create an SDV and SDPVs. An SDPV is a volume that configures an
SDP. The SDP allocates free space when SDV capacity is insufficient.
