Troubleshooting tape drives

To determine what device paths are available on your system:

1.Insert a tape into the tape drive.

2.Enter the following commands: mt -f /dev/rmt/0 status mt -f /dev/rmt/1 status

If the device path is correct, a message that is similar to the following is displayed:

HP DAT-72 tape drive:		residual= 0 retries= 0
sense key(0x0)= Unit Attention		residual= 0 retries= 0
file no= 0 block	no= 0

If the device path is incorrect, a message that is similar to the following is displayed:

/dev/rmt/0c: No such file or directory

If there is no tape in the tape drive, a message that is similar to the following is displayed:
