Good Day,
 
I have a problem with a ML2 tape.  It is damaged.  We do not have duplexing done in this partition.  My question is if I issue the RECYCLE command will DFHSM ask the tape to be mounted?  If DFHSM does request this tape be mounted this will cause us more problems.
 
Thanks

If the tape is totally damaged and unreadable, then I would use the HSM backups of the files on the ML2 tape to recover each dataset. There's a command to get all of the files on the ML2 tape, and you can then HDELETE each dataset, and then recover each dataset.

Once each file is recovered, then the ML2 tape should show up as empty, and you can just recycle it logically and HSM will release it. No mount is required for a recycle if the tape is logically empty.

If the tape has any valid data on it, DFHSM will request a mount to try and recycle the data. You'll need to remove the tape from DFHSM control, delete the entries from the MCDS and then recover any/all of the files from their BCDS backup copies to recover the data.

In the Data Recovery Scenarios chapter of the z/OS DFSMShsm Storage Administration Guide is a case called Overwritten Migration Tape which you may find helpful in determining a corrective action for recovery of your damaged tape.
There also is a job example of how to interogate the MCDS to build recover commands.
