eldo,

Your kudzu output sounds like it's seeing the SCSI controller--but that's not the SCSI hard drive itself.

The detection of the SCSI controller is a good first step, though.

I think that's an older Fast SCSI PCI host controller. Does this particular SCSI controller have a configuration tool you can enter via some sort of keyboard shortcut when its ROM information is displayed during BIOS initialization? If so, I would verify the controller isn't being prohibited from scanning for attached devices (whether via a disabled internal and/or external bus, or incorrect bus termination settings).

Is the drive known good? A faulty drive might not be seen by the controller; a dead drive almost certainly so.


More than likely I would hazzard a guess there's an issue with termination--verify you have that set correctly and/or try another SCSI device cable, just in case.


Good luck!

Check the output of the lsmod command to see if the controller module is being loaded. The module name I believe will be buslogic. You also need to check what SCSI modules are being loaded too.

Are there any other SCSI devices connected to the controller? If this is the last drive in the chain is the bus terminator installed or enabled?

BTW you did not provide any info on what linux distribution you are running or if the SCSI controller is working.

Hi,

I running on Centos 5.3,

lsmod doesn't contain any buslogic module. Yes i have connected disk drive to the controller.

Thanks,
ELdo JOseph

What happens when you try loading the module i.e.
modprobe buslogic

Looks like your going to have to recompile the kernel.
