Hi Nicholas

You don't say what your tape technology is.  I used to admin a site that
had LTO1 and LTO3 drives.  With the LTO1s I would run move data on any
tape in error, and if that worked record the volser of the tape.  After
three errors, or if the move data didn't work I would discard the tape.
For the LTO3s I discovered that any error tended to be permanent.

I currently work a lot with LTO2s and they fail similarly to LTO1s, but
more of them fail hard on the first error.

Regards

Steve.

Hello All,

Thanks for your help!!

The volume inventory here is rather old here(2002). There tends to be
many read and write errors in the volume inventory. I was looking for a
rule of thumb regarding how many errors trigger disposal of these
volumes.

I have been disposing of them at the first sign of either read or write
failures but I am seeing so many, I am beginning to wonder if some level
or read/write errors is acceptable. Any thoughts on this will be
appreciated.

Nicholas
