Re: Saving data on a defective cartridge

We have had success doing exactly what Doug suggests below. Sometimes it
requires deleting more than one file.
First, try doing a move data. Keep doing a Q PROC to see how many files
(if any) the MOVE DATA succeeds in moving. Oft times, the bad file is not
the first on the tape. THis is because of file aggregation. When MOVE
DATA aborts, it backs out the move of all the files in the aggregation.
Then, do a Q CONTENT COUNT=nn, where "nn" is the number of files
successfully moved by MOVE DATA + 1. This will tell you the filename.
Then do what Doug suggests - find a way to purge this file from TSM. We
did what Doug suggests, which is to backup the same file enough times that
the copy of the file mapping the bad spot on tape expires. Once this
happens, try it all again. There may be more than one file mapping onto
the bad spot.
It would be much easier of TSM handled this more gracefully.
Or, use copy storage pools.
Or, if you're using DLT, use something else. We've had good luck with LTO.

The next step is to beg management for enough blank cartridges to set up
a copy pool.
