20140322: Enabling SSH Access to a Clustered ONTAP system Before Completing Cluster Setup

In the below, first break the "Cluster Setup Wizard" by typing "exit" or using Ctrl+C, then run the following commands. The following commands have us create an IP Address for node-mgmt on the node-mgmt port e0M.

network interface create -lif mgmt1 -role node-mgmt -home-node localhost -home-port e0M -address -netmask

security login password -username admin

security login create -username admin -application ssh -authmethod password -role admin

Optional step: For if you need to be able to route to the node-mgmt IP created above before completing the "Cluster Setup Wizard".
