Unless the migration away from Physical Tape was done by people
completely unfamiliar with Mainframe processing....
Change 'tape' to 'Virtual Tape Subsystem Objects'
Although we used the DRVendor's floor system to run the restore, we
could have had them 'mount' our DR z/VM or DR z/OS system image to
restore first. But we did the whole DR exercise without Physical Tapes.
DRVendor was more than 300 miles away.

Ransomware is much in the news these days. As unlikely as it might be, some
nefarious genius manages to lock you out of your entire disk farm and demands
rubies and bitcoin to remove the lock. Meanwhile your shop is out of the water.
You have everything meticulously mirrored to another site, but as with any good
mirror, the lock has been reflected in your recovery site.
The classic mainframe response--short of forking over the ransom--would be to
IPL a standalone DSS restore tape, then locate and mount standard offload
backup tapes. Restore enough key volumes to IPL a minimal system, then proceed
to restore (all) other volumes. It will take a while, but it will work.
Eventually.
Now consider a smartly modern shop that has taken the advice of a generation of
hired gurus and eliminated 'real tape' altogether. No more physical tapes. No
more physical tape drives.
What would be your sage advice?
