tape device 1

[Midrange]

Newbie to redhat.

i have an internal tape drive and i want use it. I managed to see the drive on /proc/scsi/scsi but the problem i cannot locate what device name he is attached. I checked the dmesg but no st0, etc..

do i need to link the device before i can use it? what procedures i need to undertake.

thanks.

Do a cat /proc/devices and see what block/character device number is assigned to device st. On my server it shows

Character devices:
1 mem
2 pty
3 ttyp
4 /dev/vc/0
4 tty
4 ttyS
5 /dev/tty
5 /dev/console
5 /dev/ptmx
7 vcs
9 st
10 misc
13 input
21 sg
29 fb
36 netlink
128 ptm
136 pts
180 usb

that my tape drive is character device 9. Now we need to create a node to the device. Use the command:

mknod /dev/[node_name] c 9 0
i.e
mknod /dev/st0 c 9 0

IIRC, you can create another node, changing the 0 to 128 to make your device to not rewind the tape when it ejects. Good for appending data to tape.

With regard to the last line of zeland's post, st0 is typical with rewind after each action, and nst0 is without (for appending to the end).
