Hi, I try to mt -f , but failed.

# mt -f /dev/st0 rewind
/dev/st0: No such device

# mt -f /dev/sg0 rewind
/dev/sg0: Permission denied

What's the problem?

I'm running RedHat 7.2, kernel 2.4.7-10

# ls -al /dev/st0 /dev/sg0
crw-rw---- 1 root disk 21, 0 Aug 31 2001 /dev/sg0

Hi!

Just a few quick tips:

1. Try all the st,sg devices
in the /dev directory:

# mt -f /dev/st0 status
# mt -f /dev/st0 status

2. Use the stinit program
to initialize the tape drive.
(/sbin/stinit)

3. I hope, you try the mt commands with root account... ;)

yes, I login as root.

[root]# mt -f /dev/st0 status
/dev/st0: No such device
[root]# mt -f /dev/st1 status
/dev/st1: No such device
[root]# mt -f /dev/st2 status
/dev/st2: No such device
[root]# mt -f /dev/sg1 status
/dev/sg1: Permission denied
[root]# mt -f /dev/sg0 status
/dev/sg0: Permission denied
[root]# mt -f /dev/sg2 status
/dev/sg2: No such device or address
[root]# ls -al /dev/sg2
crw-rw---- 1 root disk 21, 2 Aug 31 2001 /dev/sg2
[root]# ls -al /dev/sg1
crw-rw---- 1 root disk 21, 1 Aug 31 2001 /dev/sg1

any example for stinit.conf?

i think /proc/scsi/scsi looks strange...

[root]# echo "scsi {remove,add}-single-device" 0 0 3 0 > /proc/scsi/scsi

there is no effect, still shows this...

Umm, judging by the contents of your '/proc/scsi/scsi', it would seem that the tape drive isn't being recognised at all.

The only Ultrim drives I know are logically badged HP or Quantum (from memory), and show up something like:

Vendor: HP Model: Ultrium 1-SCSI Rev: E0AD
Type: Sequential-Access ANSI SCSI revision: 03

I'd be going back to making sure the device is recognised at bootup, checking cabling and SCSI ID's.

The two entries showing above appear to be disks, not tape drives.

You are right.
My tape should be in scsi host 1.

now i get this,
Host: scsi1 Channel: 00 Id: 03 Lun: 00
Vendor: HP Model: Ultrium 1-SCSI Rev: N23D
Type: Sequential-Access ANSI SCSI revision: 03

Thanks!
