Mac Pro shuts down after setting up RAID (HELP!)
So, I recently purchased a rev 1 Mac Pro and decided to setup a RAID using 4 750gb WD drives. I am not using a RAID card, simply using Disk Utility.
I first combined drives in bays 1 and 2 (striped) and then combined drives in bays 3 and 4 (striped) to give me essentially two 1.5tb drives.
I then created a mirrored RAID using the two striped raids so that I would have the speed of a striped RAID with the safety of a mirrored RAID.
Once I did this, it showed up as one hard disk on my desktop (I was booting with an external). I then cloned my external drive to the new RAID disk on the desktop, and did so successfully.
However, now when I try to boot from the RAID, it chimes, the Apple appears, and then the Mac Pro shuts down. I tried holding down option and all 4 drives appear. I tried booting from a different drive, and the same thing happens. I should also note that the firmware bar flashes on the screen before shutting down (looks like a really long pill).
Any ideas? Does it sound like I did something wrong? I hate to start from scratch, as it takes all night to clone my external drive to the Mac Pro. Thanks for any help.
