RAID Array failed, system won't Boot.
Posted on 2007-03-23
First, I know very little about this situation, and I am the most knowledgeable one in our company. I am the "IT" guy. My (third party) hardware installers seem to know not a whole lot more, thus the questions.
We have a server with an adaptec scsi RAID system. Last night there was a power failure and the system failed to boot when restarted this AM. A call to the (3rd party) network guys brought them out, but we were unable to get the situation resolved.
Presumably we have a 3 array system.
Array 0 has 2 36g drives, RAID 1, mirroring the operating system.
Array 1 has 2 36g drives, RAID 1, mirroring (I think) our GP and SQL server installation
Array 2 has 4 36g drives, RAID 5, holding our DATA.
The adaptec software reports:
Array 0, shows 2 drives, Raid FAILED
Array 1, shows 1 drive, missing member
Array 3, shows 4 drives, optimal
When the system boots, the SCSI controller does its thing, reporting on the RAID, then ultimately the system arrives at:
NO OPERATING SYSTEM found
There are red light error indications on a couple of the drives. We moved the Array 0 and 1 drives around somewhat to different slots, in the hope that a "slot" was bad.
I would appreciate any help on what NOT to do as well as what TO DO at this point. Some of my concerns:
1. Would moving the drives "ruin" any data on the drives.
2. Given that the RAID is not working right, can we somehow use the drives to get our systems back?
3. Is it likely that our RAID controller is faulty? If so, could we replace it and still get our data from the existing drives?
Obviously, our concern is to get back up and running ASAP.
