Backup tapes on Linux problem

g0all used Ask the Experts™

I'm having some problems with the backup tapes:

mt -f /dev/st0 status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (50000):

cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 03 Lun: 00
  Vendor: HP       Model: Ultrium 3-SCSI   Rev: G64D
  Type:   Sequential-Access                ANSI SCSI revision: 03

tar tvf /dev/st0
tar: /dev/st0: Cannot open: Input/output error

tar tzvf /dev/st0
tar: /dev/st0: Cannot open: Input/output error
tar: Error is not recoverable: exiting now

Can somebody help me with these issues?

Thank you!

As far as I know DR_OPEN means "Door Open", i.e. no tape reel/cartridge loaded.

If the drive is loaded nonetheless it might have to do with dusty/dirty sensors/heads, a stuck microswitch or the like.


Hi wmp,

I'm not able to check it right now, but I will post later if any problems!
