EMC HBA Layer

A HBA, or Host Bus Adapter, is the interface card which connects a host to a SAN (Storage Area Network). It is an electronic circuit board and/or integrated circuit adapter that offers input/output (I/O) operations and physical connectivity among a server and a storage device.

Using the Clariion HBA Ports test attached to this layer, you can verify whether the HBA ports are connected to the fibre channel, and identify ports that are not trusted or defined.
