Hello everyone,

I recently took my mac pro into the Apple store to be worked on. They ended up replacing the backplane, and in the process they apparently broke the original RAID card. They then replaced that free of charge, but I now have problems. The RAID volume is no longer being reported, so the machine doesn't boot. If I boot from the install media, I can see each drive separately in disk utility. When looking at raid utility, absolutely nothing shows up. I can't see my volumes, or the drives themselves.

Does anyone happen to know what is going on here? I'm hesitant to take it back to the same place that just broke it.
