   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. When Switchover Mode is set to Enable ALUA, you need to set Path Type, whose possible options are Optimal path and Non-optimal path.
   IP Address	Indicates the IP address of the host. NOTE: If the host is connected using iSCSI links, enter the real service IP address of the host for easy management and search.
   OS	Indicates the type of the operating system running on the host. Possible values are Linux, Windows, Oracle, VMware, and XenServer. NOTE: The selected operating system type must be the same as that of the application server connected to the storage system.
