After applying some updates and rebooting one of the servers (Server 2008 R2) there was no boot volume detected. The BIOS just cycled the boot order and never loads. It just says Drive 0: Failed Boot. This is an IBM X server, 3620 M3 to be precise with a 5015 RAID controller.
I am able to start the MegaRAID tool and it appears that everything is in order. Can see the drives, everything is green and looks good to go. During POST, I see the message that 1 virtual disc was found.
The server was acting squirrely before I rebooted it. It usually gest restarted every weekend but it has been at least a month since last reboot because of other projects.
With the RAID screen looking good, that lead me to believe that perhaps one of the updates confused my OS and was hiding it from the system. I popped in the server repair disc and it fails to see any drives.
On the IBM Forums, there was a note about older BIOS versions being unable to boot so I did the task of using their build-a-disc utility with all of my specific drivers/firmware on it and ran that on the server. It updated everything successfully, or so it says, but no luck.
I don’t want to tinker too much in the RAID tool since I don’t think that is the problem. But Im not sure how to get my OS repair going if it cannot find the drive where the OS is installed.
This is our exchange server and I pray I don’t still have issues Monday morning but just looking for some info to stop chasing my tail. I’ve made no progress. Booting into Diagnostic mode once more to look around.
I think I may download the ServerGuide CD from IBM to see if that has any options, but just grasping at straws here. Any other input is indeed welcome.
