   Parameter	Description
   Switchover Mode	Indicates the path switchover mode. Modes Disable ALUA and Enable ALUA are supported. NOTE: The multipathing mode type of a host initiator: ALUA is a multi-target port access model. In the multipathing state, the ALUA mode presents active/passive volumes to the host and provides a port access status switchover interface to switch over the working controllers for volumes. For example, when a controller fails, the status of the controller port is set to Unavailable. After the host multipathing software that supports ALUA has learned the status, it switches I/Os from the failed controller to the peer controller.
   Path Type	Indicates the path type of a host.
