TSM Server 5.3.2.2 on Windows 2003 server
Dell Powervault 136T library with IBM LTO-2 drives.

If I put the tapes in and run a LABEL LIBV they label just fine. If we insert 
unlabeled tapes in the library, when TSM mounts one,
gives the I/O error reading tape label but then puts the volume in PRIVATE 
status to prevent re-access. The library is configured
AUTOLABEL=YES.

The only thing I can think of is that the drives are LTO2 and all the tapes 
they are using are LTO1. It's a hand me down system.
They had the tapes from an old Veritas implementation and their parent company 
gave them the library. And they don't have budget to
buy all new LTO2 tapes.

The devclass is set as FORMAT=DRIVE.

Any ideas? I searched ADSM-L and IBM without success...but I may not have hit 
on the right combination of keywords for the query..
