CA Disk issues several types of enqueues during processing. Some enqueues are the result of normal system services such as dynamic allocation. Others are issued for internal CA Disk functions. For more information about the enqueues, dequeues, and reserves issued by CA Disk, see the section ENQ/DEQ/Reserve Usage. If you use CA Disk in a multi-system environment, make sure that all enqueues are propagated across all systems. Failing to do so can result in problems later.
Note: When a reserve against a CA Disk FDS is converted to an enqueue, both SCOPE=SYSTEMS and sysparm RSUPPRES set to a Y need to be in place for a GRS environment to function properly.
