<div>I would tend to think the mmaddnode would fail, as GPFS recognizes that this node is already part of an existing cluster (due to the content of /var/mmfs)<br>
So following the steps in the admin guide, how to permanently remove GPFS from a node (related to the /tmp/mmfs and /var/mmfs dir) would be recommended </div>

Marcy, I believe this should work. The mmshutdown is crucial in ensuring the operation is successful, even though mmdelnode checks to ensure the node is no longer up. I’d probably wait a few mins between the delete and the add to the other</div>
