The existing optional FASTREPLICATION parameter on the SETSYS command specifies which copy method to use for data set level recovery, along with other fast replication options. To request that DFSMShsm direct messages for each fast replication backup or recover copy pool command (or auto dump of a copy pool) to a unique fast replication message data set, issue either SETSYS FASTREPLICATION(MESSAGEDATASET HLQ(hlq)) or SETSYS FASTREPLICATION(MESSAGEDATASET(YES) HLQ(hlq)), where hlq will override the default high level qualifier of HSMMSG that will be used for fast replication message data sets. To disable this function, issue FASTREPLICATION(MESSAGDATASET(NO)).
For more information, see the SETSYS FASTREPLICATION command description in z/OS DFSMShsm Storage Administration.
