Discovering storage systems
You can use the Discover Storage Systems dialog box to discover storage systems or an active/active configuration on a network subnet and add them to the list of managed systems.
Before you begin 
DHCP must be enabled on the network, which enables you to discover storage systems on a network subnet and add them to your list of managed systems.
Steps 
1.
From the Home tab, click Discover.
2.
In the Discover Storage Systems dialog box, enter the IP address and click Discover.
Note: You can type an IP address in any of the following formats: A.B.C.D, A.B.C, A.B.C.*, or A.B.C.D/24.
3.
Select one or more storage systems from the list of discovered systems and click Add Selected Systems.
Note: If you are adding one of the storage controllers from an active/active pair, the partner system is automatically added to the list of managed systems.
4.
Verify that the storage system or the active/active configuration that you added is included in the list of managed systems.
