Adding storage systems
If you know the host name or IP address of a storage system, you can add a storage system by using the Add dialog box. You can add storage systems that are in a HA configuration.
About this task 
If you are adding one of the storage systems from a high-availability pair, the partner node is automatically added to the list of managed systems. If a high-availability partner node is down, you can add the working storage node.
Steps 
1.
From the Home tab, click Add to add a storage system.
2.
Type the fully qualified DNS host name, or the IPv4 or IPv6 address of the storage system and click Add.
Result 
The storage system or the high-availability pair that you added is included in the list of managed systems.
