Moving volumes with SnapShot

DFSMSdss can use SnapShot during a physical full volume copy operation when the source and the target devices are in the same RAMAC Virtual Array (RVA). SnapShot is much faster than traditional methods of data movement, especially when you are moving large amounts of data.

For the best performance during full volume copy operations, specify the following keywords:

ADMINISTRATOR
ALLDATA(*)
ALLEXCP
PURGE

The performance improvement that is provided by these keywords is most significant when DFSMSdss uses FlashCopy® or SnapShot to perform the copy.

For more information about how to use the ADMINISTRATOR, ALLDATA, ALLEXCP, and PURGE keywords, see Explanation of COPY Command Keywords.
