NetBackup™ Flex Scale Release Notes

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.
