Before you use System Manager to manage your storage systems and clusters, you have to add them to the application. You can also add storage systems that are in an HA configuration.
If you are adding one of the storage systems from an HA pair, the partner node is automatically added to the list of managed systems. If the partner node in an HA pair is down, you can add the working storage node.
You must specify the SNMP community and SNMP version (SNMPv1 or SNMPv2).
Although you can use SNMP to communicate with the nodes, you must provide the controller credentials to manage these nodes.
You must specify the Data ONTAP credentials (user name and password) of the storage object that you are adding to System Manager.
You can use SNMP to communicate with the nodes. However, controller credentials are required for managing the nodes.
