After performing a wipe operation, the appliance will no longer operate without being returned to Cisco for reimaging. Wipe should only be used on a cluster node after that node has been flagged in OpAdmin as permanently removed. Do not remove a node from a cluster; instead, wipe it and then re-add it. Otherwise, if that node ever becomes master after being re-added, undesirable outcomes may result.
Use the Remove button in OpAdmin to inform the system that the node is removed, not just inactive.
