Question Cannot backup to tape with current software


Hi,

I'm unable to see work the tapedrive in Linux AS 2.1.

tapeinfo -f /dev/st0
cannot open SCSI device '/dev/st0' - No such device

The hardware boot recognizes the Tape drive but not Linux

I added a line in the /etc/fstab and rebooted. Here is the message: Unexpected file type for /etc/fstab.

There is no /dev/tape file. Closest was /mnt/tape.

Tried 'mount /dev/st0 -t auto /mnt/tape' but got error:
'/dev/st0 is not a block device'




any sugestions to solve this problem?

1. What kind of tape drive is it?

2. Please list the boot messages.

I suspect Linux may not have the driver installed. Linux may know it's there, but it may not know how to talk to it.

SCSI devices don't always work out of the box. Onstream is a good example.

I am running on a IBM AIX Box using a 20/40GB DDS/4 4mm Internal Tape Drive. (SCSI)

THe HWCONF file has this entry fior my tape drive:

class: TAPE
bus: SCSI
detached: 0
device: st
driver: ignore
desc: "Seagate DAT 9SP40-000"
host: 0
id: 6
channel: 2
lun: 0

My CD-ROM also says driver: ignore and it works fine.

Thanks for you input!

New /etc/fstab entry:

/dev/st0 /mnt/tape auto noauto,owner,k
udzu 0 0

Rebooted machine and got this log file message


updfstab: unexpected file type for /dev/st0

Also - The /mnt/tape dir was added by me manually because it did not exist.

Only device for tape in /dev is /dev/tape-d and /dev/tape-reset

What brand is your tape drive?

Also, I'd like you to do is type 'dmesg > dmesg.txt', edit out irrelevant stuff, and post it here.

Oh yeah, what does 'cat /proc/scsi/scsi' say?

Ah, it's a Seagate. Looks like I'm paying attention...

Try these commands:
mt -f /dev/st0 status
mt -f /dev/nst0 status

Do any of those work?
