Load a tape into the drive you want information about.
Display tape drive information with the mt command.
# mt -f /dev/rmt/n status |
Repeat steps 1-2, substituting tape drive numbers 1, 2, 3, and so on to display information about all available tape drives.
This example shows status for a QIC-150 tape drive (/dev/rmt/0) and an Exabyte tape drive (/dev/rmt/1).
$ mt -f /dev/rmt/0 status Archive QIC-150 tape drive: sense key(0x0)= No Additional Sense residual= 0 retries= 0 file no= 0 block no= 0 $ mt -f /dev/rmt/1 status Exabyte EXB-8200 8mm tape drive: sense key(0x0)= NO Additional Sense residual= 0 retries= 0 file no= 0 block no= 0 |
Here is an quick way to poll a system and locate all tape drives. In this example, the tape drive is at 0.
$ for drive in 0 1 2 3 4 5 6 7 > do > mt -f /dev/rmt/$drive status > done Archive QIC-150 tape drive: sense key(0x0)= No Additional Sense residual= 0 retries= 0 file no= 0 block no= 0 /dev/rmt/1: No such file or directory /dev/rmt/2: No such file or directory /dev/rmt/3: No such file or directory /dev/rmt/4: No such file or directory /dev/rmt/5: No such file or directory /dev/rmt/6: No such file or directory /dev/rmt/7: No such file or directory $ |
