The FASTREPLICATION keyword specifies whether the use of fast replication is required, preferred, or not desired for the CONSOLIDATE operation. This keyword applies to fast replication methods, such as FlashCopy® and SnapShot.

REQUIRED

Specifies that fast replication must be used. If fast replication cannot be used, DFSMSdss stops processing the current data set, and continues with subsequent data sets. If you do not specify the DEBUG keyword, DFSMSdss issues summarized information to indicate why you cannot use fast replication.

PREFERRED

This is the default. The PREFERRED keyword specifies that the use of fast replication is preferred. If fast replication cannot be used, DFSMSdss completes the CONSOLIDATE operation using traditional data movement methods.

NONE

Specifies that fast replication should not be used. DFSMSdss completes the CONSOLIDATE operation using traditional data movement methods.
