You are correct in that it shouldn't have to be that way - and that's one reason I did not jump on the termination right away. Evidently I have cheap caddies <G>.

Followup for the archives. With the help of several it turns out to be termination (surprise!!! <G>). I've used non-RAID SCSI for years and have always been paranoid about terminating. However, this system was set up for me by someone that I assumed (yes, I know <G>) knew RAID better than I did. The drives are in caddies that are hot swappable and the drive ID is assigned by the caddy frame. Consequently the installer did not put any jumpers on the drives and did not terminate the last drive.
Thanks all.
In a cabinet as you describe, it is normal to put a terminator on the cabinet, not the drive. Maybe that is what you did, but you made it sound like you installed a jumper on the last drive. In a cabinet as you describe you would not put jumpers directly on the drives. If you did so, then it makes it harder when replacing a drive. All drives should be just plug and go.

Termination, Cabling and/or Drive Firmware Incompatibilities. Good idea to get your TSID ready, list of components and their firmware versions and call Adaptec Support and work through the discovery cookbook.

I'm running a Linux system with a Adaptec 3210S controller. Right now the system has nothing on it and I have not created any RAID. I've notice that when I boot into the Adaptec CD and watch the drives they keep getting flagged as missing. If I do a "Read system config" the drives show up and the flag goes away. A few minutes later they are flagged as
missing again. This is a little discouraging as it appears I have a problem. Any ideas on what is happening - why do my drives keep getting
flagged as missing? I need to find out before I install Linux!
Thanks.
