Step 2: Quiesce source volume activity

This step is part of the larger task of creating volume copies with FlashCopy® or SnapShot. Access to data sets on the source volumes to be copied must cease before (and through) the COPY step. Access to the source volumes can be controlled through a hardware consistency function (if available), the IMSSETLOG SUSPEND command, or by stopping the source IMS.

See Cloning IMS subsystems for specific IMS cloning instructions. Quiescing source volume activity is a prerequisite to Step 3.
