Unhappy IBM tape Drive problem


I am totally new to Linux, i have installed Enterprise Server AS v4 successfully and all appears to be working fine except the tape drive..although it may be working and i just don't know where to look to find out..haha..the drive is working in that i can see it during the bootup of the server during the SCSI inquiry on the card...but once i get logged into Linux i have no clue...i found the Hardware Browser and i don't see the tape drive listed there...i am not even sure if it is seeing the SCSI card that it is plugged into or not either....it is plugged into an IBM Ultra320 SCSI card and the tape drive is an IBM DLT VS160....the server is a an IBM xseries 236....i installed the Amanda Tape backup system that i found on the CD's that came with the Linux distrubution it but after it installs i can find no menu item referencing it on the X windows desktop or in the Applications + Actions menus at the top...so now i am at a loss..so hopefully someone can assist or point me in the right direction...thanks

Tape drive devices are /dev/st0, /dev/st1... & /dev/nst0, /dev/nst1....
Look at the output of lspci. This will display the chipset information for the SCSI card. Post the output. You can look at the output of the command lsmod to see if you see anything that looks like the SCSI controller. You should see several SCSI modules too. Make sure the SCSI tape module st is loading.

The SCSI controller and the tape modules are not loading. Try the commands:
modprobe aic7xxx
modprobe st

You should be set.

If you have the utility mt installed on your system try the following command.
mt -f /dev/st0 status

I've never played with Amanda so I can not help you there but it isn't a GUI application.

i tried to run the mt command you specified but it said no such device, so i looked in /dev and there is no "st0" or "st" anything and no "nst" anything either

Look at the output of dmesg command after the modules are loaded. Are there any messages relating to the tape drive?

What desktop are you running? KDE or Gnome etc... Kdat is a KDE GUI frontend for the tar utility. You can also search www.freshmeat.net for backup solutions. Arkeia Server Backup I believe is GUI.
