Recently, we have been experiencing a high number of media errors (generally 
read errors with some locate errors) on our 3584 LTO library.  A recent query 
of the volumes table shows that we have 37 tapes (out of 250) with read errors! 
 We have had IBM out to inspect the library and drives, and they report that 
everything is fine.  Is it normal to have this many errors?  Could we have that 
many bad tapes?  The tapes are not rewritten very often (the data being stored 
is for a long term and is generally very static).  Has anyone else experienced 
these kind of media issues?

We are running TSM 4.2.2.13 on Win2K, the library is connected via LVD SCSI, 
and all the firmware on the drives are up-to-date.

Thanks in advance.
Peter
