Add and manage volumes in the Host Setup wizard
The Volumes section of the wizard provides options for you to add and manage volumes. By default, the system presents one
volume on each pool, with each volume size defaulting to 100GB. The wizard lets you change the volume name and size and
select the pool where the volume will reside. Follow the instructions in the wizard to create the volumes shown in the table. Be
sure to balance volume ownership between controllers. Once you are ready to move to the next step, click Next.
Configuration summary
The summary displays the host configuration you defined in the wizard. If you are happy with the setup, finish the process by
selecting Configure Host. The volumes created are mapped to the host with read/write access and are visible on all four ports,
and LUNs are automatically assigned.
Overall system status
The Home topic provides an overview of the storage managed by the system. This storage could be virtual or linear. Information
is shown about hosts, host ports, storage capacity and usage, global spares, and logical storage components (like volumes,
virtual snapshots, disk groups, and pools).

● Port information
● Capacity information

● System health information
● Spares information
Host information
The Hosts block shows how many host groups, hosts, and initiators are defined in the system. An initiator identifies an external
port to which the storage system is connected. The external port may be a port in an I/O adapter in a server, or a port in a
network switch. A host is a user-defined set of initiators that represents a server. A host group is a user-defined set of hosts for
ease of management.
NOTE:
If the external port is a switch and there is no connection from the switch to an I/O adapter, then no host
information will be shown.
Port information
The Ports A block shows the name and protocol type of each host port in controller A. The port icon indicates whether the port
is active or inactive:
The Ports B block shows similar information for controller B.
Hover the cursor over a port to see the following information in the Port Information panel. If the health is not OK, the health
reason and recommended action are shown to help you resolve problems.
