When using , 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 , 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.
