Dead nodes appear in groups when a node has been permanently removed from the cluster without SmartFailing the node. These appear similar to down nodes, except that they are marked as dead rather than down:
{ 1-5:0-11, 6:0-7,9-12, 7-10,12-14:0-11, 15:0-10,12, 16-17:0-11, dead: 11 }
If confronted with a dead node, the best course of action is to immediately contact Dell Support and immediately start a FlexProtect job.
