Hello,

Have anyone experience with Errno = 23, 1167 and stuck tapes or a suggestion 
what might cause the errors and how to solve them?
I get the errors in all kind of datamovement processes, D2T, T2T. Errors are on 
all drives randomly but not all the time.
That is, I can have 1 or 30 mounts before I get an error on a drive and the 
faulty tape mounts OK in another drive.
OS-, switch- and TSM logs etc does not provide any helpfull information.


W2k3 x64 sp2, TSM 5.5.2.1
5 LTO-4, SL500, 3 dual channel HBA´s connected to the SAN with one device per 
channel.
Lastest firmware drivers etc


First, err=1167, space reclamation mounts a tape and the drive disappear, why? 
However after some minutes TSM resurrect the drive and
continue to use it in new processes.

Second, err=23, a write errors generates error=23 and the tape is stuck. TSM 
nor Lbtest can remove the tape.
