5.2.14 Initialize Snap Data Volume
This function initializes an SDV.
An SDV is a copy destination volume for SnapOPC and SnapOPC+ that includes a data area and a copy control
information area. SDV initialization is performed when the capacity that can be used for the data area is
insufficient due to a large amount of writing being requested from the host to an SDV for any reason (such as
an operation mistake). SDV initialization is also performed when no more writing is allowed due to a
notification being reported to the host for a writing request that exceeds the SDV capacity.
•After initializing an SDV, any data that is stored in the SDV cannot be accessed. Make sure to backup the
required data.
•This function cannot be used under the following conditions:
-When the target volume is not an SDV
-When LDE is being performed in the RAID group to which the target volume belongs
-When the target volume status is not " Available"
-When Advanced Copy is being performed in the target volume
When an SDV is initialized, the area that is allocated from the SDPV to the SDV is released.
