Have one of these units and an expansion array.  They've been encrypted and are talking to a KMS, no problems there. 

I've recently discovered an issue with the KMS deploy that may require a rebuild.  There's a lot of work that could be lost if this goes sideways in regards to losing keys and/or comms to the KMS.  Last thing I want is a lot of nerds angry with me for losing data.

I'm trying to be as safe as possible for this issue until the KMS issue is resolved, so am opting to decrypt everything that uses this KMS.  So far, so good, but I'm coming up empty for anything regarding how to disable/decrypt the storage on these Compellent Arrays. 

Anyone have any pointers or know of any docs out there for this process?
