Thanks for the replies. I ended up installing a new BO and setting up all users. My fault for not having a recent backup. I never thought I would have a raid go out on me like that.
I was never able to check to see if I could load the disk partitions. When I loaded the system with a rescue disk I could sometime see the drives, maybe sdb1 and sdb2 but I was never able to load them, some kind of LVM error. Because of those LVM issues this time around on one of the new installs I just did the install without LVM. What is your recommendations on new installs? And why are LVMs so difficult to deal with after a crash?

Hit one of my customers on two BX servers, but not three others - after a power outage long enough that the UPSes failed. It appeared the kernel had updated, but without updating everything. I'm not sure if the problem was the difference in the /boot/grub/grub.conf file versus the /etc/grub.conf file. Or if it was the startup files in /boot/ that load the LVM drivers so the kernel can boot from the LVM partition. But I found a simple fix. Boot with the rescue disk and mount the partitions. Go into the /boot/grub/grub.conf file. Remove the "hiddenmenu" command. Save and reboot. Now when you try to boot the machine - the Grub boot menu will come up. Select the oldest kernel and boot it. That one SHOULD work. Once you've got the machine running, you can repair the /boot/grub/grub.conf file, its drivers in the /boot directory, and the /etc/grub.conf file. Then the latest kernel should boot. Have you seen that one before Michael??
