What are the chances?
February 8, 2007 by Brett
I celebrated a little too early after Tuesday’s crash. Less than 24 hours after I replaced 1 of the 3 drives, I got a call from downstairs. “Uh, your server room’s beeping.”
Oh crap.
I ran down and found this error: PERC 2/DC Array Disc 0:1 failed. Are you kidding me? What are the chances that 2 of the 3 drives in a server will fail within 24 hours of each other? I should play the lottery.
Of course I wasn’t smart enough to order a second drive when I replaced the first one, and you can’t just get a 10,000 rpm 68 pin SCSI drive at Best Buy. So I called my supplier and had 2 drives overnighted (a replacement and a spare this time).
It took me a minute (and 2 reboots) to figure out the jumper settings to set the SCSI ID, but finally I was back into good old NT4. The drive was already rebuilding and up to 6% when all of a sudden I saw a sea of red X’s and another big error: PERC 2/DC Array disc 0:1 failed. What?! It couldn’t have already failed. I started to worry that the SCSI card was going bad. I manually initiated a rebuild from the Array Manager, and (thank God) in less than 30 minutes I had a rebuilt array. Whew!
I’m not celebrating now, though. I’ll give it at least another 24 hours 
What are the chances? Well, I had both drives in a RAID 1 go bad because the controller went bad. Hope yours stays stable now!
We don’t keep a lot of spare drives around for the servers. We have two identical servers which use an array of 4 drives for the data storage. We have have 2 spares set aside for them. Replacements are about one business day away if we use those up.
I have no idea what you just said!?!?!?!?!? I think it may have something to do with mouse drivers, right?
