clase WMI de MSiSCSI_HBAInformation

El servicio de iniciador iSCSI usa la clase WMI de MSiSCSI_HBAInformation para comunicarse con el adaptador. Debe tener una instancia independiente de esta clase para cada instancia del controlador de minipuerto que se carga.

Dado que esta clase está asociada a una instancia determinada de un controlador de minipuerto de almacenamiento, el controlador de minipuerto debe registrar la clase con el nombre del objeto de dispositivo físico (PDO) determinado que administra el controlador de minipuerto.

La clase MSiSCSI_HBAInformation se define de la siguiente manera en Mgmt.mof.
