I had a weird issue where my server lost its mind and some of my drives went disabled for no reason. I fixed this by removing them one at a time rebuilding the array and readding it back in. Im down to the last drive which is one of the cache drives in a pool but it wont let me start the array if I remove the disabled drive from the pool. What should be the proper procedure to get that drive back online as part of the pool?  

Please post the diagnostics.

Try replacing cables for cache2 and then post new diags
