Node discovery for add/replace node operation fails while performing a passwordless SSH
If a passwordless SSH is performed from a cluster node whose MTU is 9000 MTU to a new node whose MTU is set to 1500 on the switch port, the SSH fails. This causes the node discovery for add/replace node to fail.
(IA-55899)
Workaround:
Make sure that switch port's MTU for the new node is set to 9000 before initiating discover node operation for add/replace node.
