A year ago, I engaged in a very helpful discussion with bobshouseofcards regarding adding reporting nodes:
Now I'm in the opposite situation. We are temporarily adding a fifth and sixth node to the cluster, migrating content to those nodes, and then decommissioning two of the original nodes. I will add nodes 5 and 6 as reporting nodes before moving volumes containing LUNs to those nodes, but afterwards I want to cleanly remove nodes 1 and 2 as being reporting nodes, but keeping nodes 3, 4, 5, and 6.
In my reading of the lun mapping remove-reporting-nodes command, it appears to be very limited compared to add-reporting-nodes. There doesn't appear to be any way to identify which nodes you want to remove.
The "-remove-nodes" option description reads: "If specified, remove all nodes other than the LUN's owner and HA partner from the LUN mapping's reporting nodes." That's not what I want, but I see no other option to determine which nodes to remove. Also, what happens if this option is not specified? Which nodes are removed? Any help would be appreciated!
