HSM_CDSB_DASD

Description:

If DFSMShsm Control Data Set backups are created on DASD, this check will ensure all required DASD backup data sets are in place.

This check is registered with IBM® Health Checker for z/OS® when the MAIN DFSMShsm host initializes on a z/OS image for the first time since IPL.

The check will run after a MAIN DFSMShsm host initializes, the CDS backup function completes on a MAIN or AUX host, a SETSYS CDSVERSIONBACKUP is issued to a MAIN or AUX DFSMShsm host(SETSYS CDSVERSIONBACKUP commands processed during MAIN host initializatin will not cause the checks to run).

This check requires a MAIN DFSMShsm host to be active on the z/OS image. If this check runs while a MAIN DFSMShsm host is not active, the check will be disabled until a MAIN host initializes.

Reason for check:

When backing up CDS's to DASD, DFSMShsm requires all backup data sets to be pre-allocated. If one or more data set becomes unavailable, the CDS Backup function may fail. A failure during CDS Backup may lead to critical functions to be held within DFSMShsm.

z/OS releases the check applies to:

z/OS V1R7 and later.
