No matter what disk I put in to replace a failed one, it wouldn't "take". 3 drives, exact model, different production dates... None took.
I futzed and futzed and finally decided to declare the cage bad and think of backout procedures. About 2 hours after I had set another machine up to take its place, it started giving spurious errors and fell over. I pulled the machine out of the datacenter, cleared out the raid config, and went to rebuild with just the 3 drives. Wouldn't build a fresh raid-5 from just the 3 disks. After the "Which one of these things is not like the other", I found that apparently one of the disks still was working, but causing heck if I put another disk in the slot next to it. A year later, and I finally decided to buy a few more disks off ebay to see if my final theory is right. I win (hopefully) the auction in 5 days... If the cage really is bad, I previously sourced a new case/cage, and decided even though its a 4G Dual Xenon system I probably could get a new system cheaper thats faster.
