You can display all storage devices or LUNs available to the host, including all local and networked devices. If you use third-party multipathing plug-ins, the storage devices available through the plug-ins also appear on the list.

For each storage adapter, you can display a separate list of storage devices available for this adapter.

Generally, when you review storage devices, you see the following information.
