SCSI Tape Drive Not Recognized

[wstran]

Greetings,

I have a Dell server 2850 with Adaptec 29160 SCSI controller card. I connected the external HP tape backup Ultrium 448 into that SCSI card. When I rebooted the server, I saw it recognized the Adaptec and HP tape drive. However, when I run Tapeware bachup software in RedHat Linux Enterprise 3.0, it did not see any device to back up into tape. Do I need to mount the tape drive or anything else to make it work? Any help will be appreciated!

The Tapeware backup software might be misconfigured. The tape drive should be either st0 or nst0.

Type
cat /proc/scsi/scsi and output what is shown.

Do you need to mount the tape drive? You should not have to. The Tapeware Backup Software should do that for you.

AS a test you can tar some files to the tape and then retrieve them.

tar -cvf /dev/nst0 /etc/

Then create a directory to restore to.
tar -C {new_dir} -xvf /dev/nst0

See of that will work. If so then basic tape functionality works and TapeWare Backup is just misconfigured.

Thanks Clonny2 for your advice! I did cat /proc/scsi/scsi and the result is:

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: MAXTOR Model: ATLAS10K5_300SCA Rev: JNZM
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 01 Lun: 00

Vendor: TSSTcorp Model: CDRW/DVD TSL462C Rev: DE01

Obviourly, Linux only recognizes two hard drives and CDRW/DVD but NOT the tape drive.

I run the test as your recommendation by tar -cvf /dev/nst0 /etc/ and it displayed tar: /dev/nst0: cannot open: no such dvice. Same error mesage for /dev/st0.

By the way, I also run command mt -f /dev/st0 status and mt -f /dev/nst0 status, but they both reported that "no such device".

That is the problem, linux itself does not recognize the tape device. Next time you reboot the server, go into the scsi bios and verify that the SCSI card actually sees the tape device. Secondly, double check cable and termination and verify that you do not have a SCSI ID conflict.

Is the tape Internal or External? Also make sure the card is terminated.
