Re: Help Please With HP Travan Scsi Tape Drive



Hi All

Thanks to Keith and Alexis for their emails and to all others who spent time considering my problem.

I reseated the scsi cable connections and the problem resolved itself.  This is what the output from the mt command should loo k like.

# mt -f /dev/nst0 status
drive type = Generic SCSI-2 tape
drive status = 1157628416
sense key error = 0
residue count = 0
file number = 0
block number = 0
Tape block size 512 bytes. Density code 0x45 (unknown).
Soft error count since last status=0
General status bits on (41010000):
