Hi A.Cecilio, 


You have already gotten some good replies that, in my opinion, should be 
followed.  There are a couple of additional recommendations I would like to 
make. 



1) You said that the cartridge is too damaged to read.  How did it get 
damaged?  It is important to find out because other cartridges may be at risk 
for the same damage, or may already be damaged and just not discovered yet.  I 
f the root cause is not identified and corrected, you may end up with more 
damaged tapes. 



2) If you are not able to read the tape, it m ight be possible for a recovery 
company to recover it and write the datasets, as many as they can recover, to 
new tapes, or to other media.   



Some years ago, on an old ATL/VTS that has since been replaced , one of the 
drives that wrote non-duplex data out of  the VTS clobbered about a dozen 
tapes.  At first, only one bad tape was obvious.  We took the create drive and 
the last used drive out of service. Turned out it was the last used drive that 
did the damage.  We were blessed that it wasn't the create drive.   The 
recovery folks did get our data back. 



HTH, 



Linda

Subject: DFHSM: Backup tape lost due to errors 

Hello, 
suppose you have an 3592-JB dfhsm cart (native, not a vts stacked 
cart) that can't be read due to physical damage, no tape backup 
duplication. Several backups are unique, no additional versions. How 
to correct bcds ?? Run AUDIT DATASETCONTROLS (BACKUP) with NOFIX (to 
check the amount corrections) and then with FIX ??? Z/Os V1.12.?? 

Any hint is welcome. 
MAny thx, A.Cecilio
