Disaster Strikes! Advice requested!

Thanks again for the response, I understand I can't rebuild the data on the disks, and I understand about backups, this device is a backup. I was just thinking it might be possible to somehow boot the os and generate a new raid set w/o destroying my os configuration in the nvram. I also don't want to go thru trying to start completely over if there is some additional problem w/ my hardware, which I sort of suspect since the blank LEDs are not what I expected for simply failed disks.
