SCSI harddrives not detected

I just bought an IBM PC Server 704 really cheap so I could learn about RAID and SCSI and I am already have trouble.

When you boot the beast I enter the SCSI config uility and goto disk tools and I see that none of the hardrives are detected.

My question is how do I configure the hardrives so the SCSI utility recognizes them?

For the record I have only one hardrive(The system came with nine drives) plugged into the rack and according to the indicator lights above each slot the hardrive is present and has power. I can hear the harddrive spin when I boot the system but that stops as the boot process starts up. I reset the SCSI options to the factory default setting. Also I tried each of the 12 drive bays and had the same results as stated above. I am very new to SCSI and I would greatly apprecate a push in the right direction or a referal to a handy website

Thanks

I think I am alright on the termination issue. According to the server manual the hard drive cage and the adaptor provide automatic termination. I am pretty sure the cdrom is alright since I can see it in the SCSI detection list - thanks for the other links I will start looking for the answer.

Thanks

You have to set the HDD Seqence in the BIOS Setup to SCSI.

First, when the system is booting up, check the "stores list" when the SCSI controller get initilized to make sure the disk is connected correctly.  Then you said the system came with 9 drive and you wanted to learn about RAID.  Were the drives RAIDed?  If so then you need to tell the SCSI controller that you "broke" the RAID array.  This might need to be done before the OS is loaded.  The controller might have a boot disk to run in DOS mode.   Remove the current configuration because the controller will still be looking for the RAID array and since it doesn't exist you will have no hard drives.  Then you should be able to see the remaining disk(s) attached to the controller.  Add the new configuration and reboot.
