So an inspection of the tape physical tape records would be one way to
get a list of all the data sets originally written on that ML2 tape, but
you would still need to look at the CDS data sets to determine which of
those data sets on the physical ML2 tape were still active and not
logically deleted. A data set owner presumably would be OK with loss of
any logically deleted data sets, as from the owners viewpoint they were
already deleted by design. That could significantly reduce the number
of data sets on the remaining ML2 tape volume. that are a concern.

When we browsed a ML1 tape on dasd, we saw the real DSN at the start of
each dataset.

Two wildly different thoughts:
1. Might it be possible to mount the offending tape manually depending of
course on what's failed in the library?
2. DFSMShsm AUDIT MEDIACONTROLS once the tape has been transported to the
main site. This probably involves less risk of bodily harm.

Hello Listers,
I have a small remote site that we are upgrading the physical tape
library
to a virtual TS7700 library. All went well until the old library had a
serious hardware error. My leadership has decided not to spend the
money
to repair the old failed library (of course now out of warranty and
maintenance). However, I still have one more ML2 tape worth of data to
migrate to the new library.
If we bring the ML2 tape back to our main site would it be possible to
read the ML2 tape to extract the data off of it? The only way I can
think
of is to also bring copies of all the CDS's and Journal from the remote
site, restore those CDS's (MCDS, BCDS, OCDS) and Journal. Then bring
down
the "real" DFHSM and bring up the "Remote" DFHSM to be able to recall the
data off of the ML2 tape.
Unfortunately running the "hsend list dsname both" commands on the ML2
datasets shows No BCDS records so I cannot just recover the ML2 datasets
from BCDS copies.
Any suggestions would be welcomed.
Thanks,
Fred G.
