8.2.2 Start SnapOPC+
This function is used to select the copy source volume and copy destination volume, and start a new SnapOPC+
copy session.
The procedure to start the SnapOPC+ session is as follows:
Procedure
1 Click [Start SnapOPC+] in [Action].
• 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 volumes. 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.
• An ODX Buffer volume cannot be specified as a copy source.
For controller firmware version V10L30 or later, the number of available generations for SnapOPC+ is 512.
