No startup disk found!

Help! I just replaced the 80gb hard drives in my Xserve with 3 500 GB drives. I set it up so bay 1 was a stand alone drive (for the OS) and bay 2 and 3 were striped. I installed 10.5 Server, everything went fine. I updated to 10.5.7 along with the other updates listed and now my startup disk cannot be found. I hold down the option key and no drives show up. Sometimes it will boot, but it flashes a folder with a question mark first. I've tried resetting the PVRAM and NVRAM, I've tried selecting my startup disk, etc. I can boot from the install media still, but none of my drives boot. I know the drives are functional, any ideas? I am currently booting from the install media, but previously my startup disk did show up when in there, but it won't boot from it. I'll post again if it does not show up anymore.

Thanks,
Tim

Xserve, Mac OS X (10.5.7)

I was having the same issue with non Apple drives, it turns out that the SATA/SAS bus on the late 2006 model of XServe only handles SATA 1 speeds and the drives need to be slowed down for 3MB/Sec to 1.5MB/sec. On the Seagate drives I am using I had to apply a jumper as indicated on the front label, your drives may vary.

Thanks Steve, this was the key to my problem of an Xserve G5 not recognizing replacement 3rd party drives. Only hitch was the drives didn't come with jumpers, so I had to call a coworker to run them down to the data center.
