Hi,

Can you do anything with the tape device ?

Try something simple like:

# mt -f /dev/tape/tape3 status

If the tape drives have been changed, then they may no longer be on tape3... Check the output of

# hwmgr view dev | grep tape


Cheers,

Rob

Typically there will be more descriptive error events in the binary errlog to go with the above. What's in the binlog around that time?
