Question SCSI tape drive


Hi Guys,

Want some help to get my tape drive work.

I have 2 SCSI disks and 1 SCSI tape drive. Disks are working fine.
But the tape drive not.

In /proc/scsi/scsi, I have

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: FUJITSU Model: MAP3367NC Rev: 5207
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 01 Lun: 00
Vendor: FUJITSU Model: MAP3367NC Rev: 5207
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 08 Lun: 00
Vendor: SDR Model: GEM318 Rev: 0
Type: Processor ANSI SCSI revision: 02


Why Type: Processor in the 3rd entry ?

When I issue " mt -f /dev/st0 status", I get "/dev/st0: No such device".

And when I issue "mt -f /dev/sg2 status", I get "/dev/sg2: Operation not permitted".

Thanks in advance for any help.

-San

do you have scsi tape support built into your kernel?

In your /proc/scsi/scsi listing I don't see anything that looks like a tape drive.

From Google, I get:
FUJITSU Model: MAP3367NC > 36GB 80PIN SCSI FUJITSU DRIVE
FUJITSU Model: MAP3367NC > 36GB 80PIN SCSI FUJITSU DRIVE
SDR Model: GEM318 > Altos G700 BPL4 disk cage

Perhaps you need to check your power and SCSI cable connections?

The only driver you need is the SCSI tape module st. What distro are you running?

If it isn't loading try:
modprobe st

It's RHEL 3.0.

[root@bear root]# modprobe st
[root@bear root]# mt -f /dev/st0 rewind
/dev/st0: No such device


May be I'll try a newer version of st ?

Check the output of dmesg. Do you see the tape drive?
Also try
cat /proc/scsi/scsi
Does anything show for the drive?

The device might be something other than /dev/st0. Do you have a /dev/scsi directory?

I tried "dmesg|grep tape". Nothing.

But for dmesg|grep scsi it gives;

Attached scsi disk sda at scsi0, channel 0, id 0, lun 0
Attached scsi disk sdb at scsi0, channel 0, id 1, lun 0
Attached scsi generic sg2 at scsi0, channel 0, id 8, lun 0, type 3

----------------------------------------------------------------------------------

My /proc/scsi/scsi is;

[root@bear etc]# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: FUJITSU Model: MAP3367NC Rev: 5207
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 01 Lun: 00
Vendor: FUJITSU Model: MAP3367NC Rev: 5207
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 08 Lun: 00
Vendor: SDR Model: GEM318 Rev: 0
Type: Processor ANSI SCSI revision: 02

--------------------------------------------------------------------------

In the last entry "Type: Processor"


And I don't have a /dev/scsi/ directory.

Is the SCSI ID of the tape drive 8?
Are you using SCSI emulation?
