Logical copy or dump
Back up mounted zFS data sets with logical data set copy or dump. This will provide the quiesce
serialization mechanism (BPX1PCT) to ensure data integrity.
For non-shared file systems,
you must run the DFSMSdss copy or dump job on the same system where the data set is mounted for
update; the quiesce is only effective on the system it is issued from. For shared file systems, you
can run the DFSMSdss job from any system in the sysplex, because the quiesce is handled globally
across all systems. TOL(ENQF) is not honored during logical dump of zFS and is not honored for a
source zFS data set during logical copy.
