Re: MSA 1500cs con

I worked very less with MSA 1000, but can suggest some thing to get a better clue on this.

Bring down the entire box and remove all the cables and IO modules. Try Refixing all HDDs and reconnect all the cables on that enclosure.

If still the same issue persists, we may need to suspect the Mid plane of that enclosure.
