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).

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.

The area between the blocks displays the following statistics that show the current performance from all hosts to the system:
• Current IOPS for all ports, calculated over the interval since these statistics were last requested - every 30 seconds unless more than
one PowerVault Manager session is active or if the CLI command show host-port-statistics is issued - or reset.
