Preparing Copy Destination Volumes

To use SnapOPC+, the same number of volumes as there are generations is required for the copy destination. Create any of the following volumes types in advance.

If the volume type of the copy destination is SDV, SDVs must be used for all generations. If the volume type of the copy destination is TPV or FTV, a mixture of TPVs and FTVs is available. Use TPV or FTV for each generation.

To create SDVs, SDPVs, or TPVs, use the [Create Volume] function. To create FTVs, use ETERNUS SF Storage Cruiser.

Caution

  • Registering the license for the Advanced Copy function is required to start a SnapOPC+ session.

  • Only SnapOPC+ copy sessions that are performed in units of volumes can be created using Web GUI. To create EC, OPC, QuickOPC, SnapOPC, SnapOPC+ sessions using range selection, and REC sessions, use copy management software.

  • ODX Buffer volumes and Data Container Volumes cannot be specified as the copy source.

  • External Volumes (or volumes whose "Usage" is "Migration") cannot be specified as the copy source or copy destination.
