The same proble we faced 2 times earlier and it got rectified after replacing CORE I/O.again the same problem comes in the same server.Theni am suspecting this is related to some configuration isse? can anybody help me on this..

"But if i do mt -f /dev/rmt/omn status"

Note the omn instead of 0mn.

Hi,

It may be a possibiliy that the tape drive has gone faulty.
