I regenerate my DR restore jobs at the end of the daily FDRABR DR back-up jobs. We use DFHSM for migration and application ack-and restore. When practicing the DR recovery, I need to restore DFHSM using the most recent CDS back-up. So, this scenario is that I've just restored all CDS (and JRNL) from the latest back-up. So, the version numder in the MCDS for the next backup is the one I used to restore. I'd like to reset that value before starting DFHSM with these restored CDSs. To me, this would be the least error prone path. I'd like it to be a step in the restore job. It seems that to do this, that step in the restore job needs to be DFHSM itself, with an abbreviated ARCCMDxx member that I'll need to also dynamically generate. In an temp PDS? So, now a three step DFHSM recovery job.
