An Ap_Id on a fabric-connected host port is a path to a multipathed device.
When a multipathed device has multiple Ap_Ids connected to it, the device is still available to the system after you unconfigure an Ap_Id. After you unconfigure the last Ap_Id, no additional paths remain and the device is unavailable to the system. Only devices on a fabric-connected host port can be unconfigured.
