Issue

One or more nodes report a stackmon.stack.id.conflict error in the event logs:

[Node-A: stackmon_thread: stackmon.stack.id.conflict:error]: Stack ID of the Shelf 30 (S/N SHFXXXXXXXXXX89) on channel Node101swb:8 cannot be agreed on by all the nodes in the cluster.

[Node-A: stackmon_thread: stackmon.stack.id.conflict:error]: Stack ID of the Shelf 70 (S/N SHFXXXXXXXXXX79) on channel Node100swa:8 cannot be agreed on by all the nodes in the cluster.

The stack IDs for shelves in different stacks report the same stack ID:

Cluster1::> storage shelf show -fields shelf, shelf-id, stack-id node shelf stack-id shelf-id -------- ----- -------- -------- C1_N1 3.50 3 50 <<< Shelf in correct stack C1_N1 3.51 3 51 <<< Shelf in correct stack C1_N1 3.60 3 60 <<< Shelf in incorrect stack C1_N1 3.61 3 61 <<< Shelf in incorrect stack C1_N1 3.70 3 70 <<< Shelf in incorrect stack C1_N1 3.71 3 71 <<< Shelf in incorrect stack
