Configuring HP Ultrium on Redhat 7.3 on an IBM x255

Vinesh Dhevcharran — Tue, 21 Jan 2003 11:18:00 GMT

Hi,

We have just purchased an IBM x255 server with an HP LTO 230 tape drive. Redhat 7.3 OS was installed with the custom option.

As per the /etc/sysconfig/hwconf, there is an entry for the HP Ultrium, howevere I cannot "see" this device on linux!!!
1. What is the equivalent to ioscan -funC tape on linux (kudzu?)
2. How do I tell what this device name is e.g. on hp-ux ioscan -funC will tell me c0t4d0BEST
3. Do I need to install any patches or make any modifications to be able to "see" this device on linux.

Many Thanks
Vinesh

Firstly, run "dmesg" and look for your tape drive and see if it's recognised.

"cat /proc/scsi/scsi" as well just to see if your tape is seen.

If it is seen, then the device is probably "/dev/st0" for the first scsi tape drive.

There is no "ioscan" on Linux but using "cat" on files in the "/proc" filesystem will display all sorts of exciting information.

Hi,

You can run /usr/bin/hwbrowser to see the hardware your system recognizes. There are also cli tools out there, lspci and lsusb.

Check dmesg or boot.log to see if the cards are recognized/installed properly. If you see unrecognized cards you'll need to load a module.

SCSI device names are usually called /dev/sda*.
Check out this link for MANY more details:
http://www.linux.com/howtos/SCSI-2.4-HOWTO/dnames.shtml

They mention a tool "scidev", I haven't used it myself, but it sounds like this could be useful.

Forgot to mention this page:

This has all the software for Linux that HP releases, AFAIK:

Good luck!

Thanks for the reply, although it has been quite some time.

I got around the problem by changing the SCSI card. See linuxtapecert.org.

There was issues with Adaptec 789x chipset based SCSI adapters at that time.
