A physical connection on the host adapter that resides within a host.
When the host adapter only has one physical connection (host port), the terms host port and host adapter are synonymous.
The host ports are automatically discovered by the storage management software. A host port is the actual physical
connection that allows a host to gain access to the logical drives in the Storage Subsystem. Therefore, if you want to define
specific logical drive-to-LUN mappings for a particular host and create Storage Partitions, you must define its associated
host ports.
