RHELv3 system cannot detect Ultrium tape device

[Gregory Lee]

My DL380 system installed with RHEL ver 3 cannot see the Ultrium tape device connected to it. It's hooked up to the SCSI adapter. During the boot-up sequence, the bios is able to list the tape device correctly at slot 6 port 8 id 3. Not sure what is meant by slot 6 - it's definitely not the PCI slot number as the SCSI adapter is installed on slot 2. The tape device is configured with SCSI ID #3.

But after Linux boots, there's no tape device in sight. No entry in /proc/scsi/scsi

My SCSI adapter (dual-port):
06:01.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07)
06:01.1 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07)

I've tried the rescan scsi script to no avail unless there are other options to try.

Tried loading module "st" but it does not help. My lsmod output:

Interestingly, when the system is booted with Knoppix, I can actually see the tape device:
Host: scsi2 Channel: 00 Id: 03 Lun: 00
Vendor: HP Model: Ultrium 2-SCSI Rev: F34D
Type: Sequential-Access ANSI SCSI revision: 03

Where is it under my Redhat system?!?!

The SCSCI card, is it LVD SCSI?

THe Ultrium drive is a LVD device and won't work ont he wrong kind of SCSI card.

Based on your knoppix boot, I'd say that the device was not built into the RH ES 2.4.x kernel.

You need to see if HP supports that device and OS combination. Sounds like you'll have to add a driver to the kernel to get it to work.

How about on a FC 3 2.6 kernel?

You could upgrade the red hat to 2.6 and that is supported by RH. If so, you can perform the upgrade and detect the device.

knoppix is based on the 2.6 kernel, yes?

Hello Gregory,

that is a known problem with many pitfalls.

Please check this discussion:

Try the rescan-scsi.sh with the options xyko used. If this fails come back to us.

Best wishes

Hi Gregory,

Hi Oliver,

I guess Greg's problem will not be solved only with the fabulous rescan utility that saved my life. I guess that he needs to load the scsi controller module before try to rescan. The module is mptfusion.o, I think, but Greg can verify if I'm correct booting Knoppix and seeing (lsmod) if that module is loaded.

regards all,
xyko

Managed to solve the problem. Looks like it was a simple case of installing the drivers provided by HP for the dual-channel Ultra320 SCSI adapter. Once I got that in, rebooted the box and the tape device appears.

BTW, the module was mptbase.o

Thanks for the hint.
