Just received three email alerts simultaneously from SAN HQ, Dell OME and EQL Group Manager all saying slot 5 in one of the Equallogic members has failed, the last disk (slot 15) kicked in and the raid set is reconstructing. Called local Dell ProSupport, parts is being arranged and will be delivered to data center within 2-3 hours. (Update, raid reconstruction took about 3 1/2 hours to complete)

It was quite a black day today as this is the 2nd incident happening to my equipment, and Equallogic SAN was under very light load and the disk just failed without any pre-warning. Where is the predicative disk failure feature in Equallogic after all?
