Depending on the version of OS (later Fedora only install the devices that are actaully in the system) I would: ls -al /dev/nst* ls -al /dev/st* to see WHICH devices are available and then decide what you need to do, e.g. mt -f /dev/nst0 status which should yield something like (if there is NO TAPE in the drive) 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): DR_OPEN IM_REP_EN There are two types of tapes nstX and stX where X is the number of the tape device. Both indicate tape driver, and point to the same device. The major difference is after performing a task, /dev/st0 will rewind to the begining of the tape, but /dev/nst0 won't. If you do not see any of those devices (assuming you have a SCSI adapter) I would do a ls -al /proc/scsi to see what ADAPTORS your system can see. If you do not see any like for example in my case dr-xr-xr-x 4 root root 0 2008-09-17 09:14 . dr-xr-xr-x 161 root root 0 2008-04-08 18:07 .. dr-xr-xr-x 2 root root 0 2008-09-17 09:25 aic7xxx -r--r--r-- 1 root root 0 2008-09-17 09:25 device_info -r--r--r-- 1 root root 0 2008-09-17 09:25 scsi dr-xr-xr-x 2 root root 0 2008-09-17 09:25 sg then you have a driver problem AND/OR your system cannot see the adaptor. If you can see something I would ls -la aic7xxx/ or whatever your driver of your adaptor is named to see whether the drives are recognised.
