In the Case of the Oceastor VIS6600T with Dual Switch

In the case of the Oceastor VIS6600T with dual switch redundancy networking, log in to the Windows machine connected to the VIS6600T and configure the set of multi-path software Ultrapath control interface to see the number of physical path than the planned network computing path less, the possibility of this phenomenon. What is the reason for this? (Multiple choice.)

A) Host to the optical switch connection is abnormal.
B) When configuring the zone on the switch, configure the FC port and the host port that works in the working mode of the VIS6600T as a target in one zone.
C) The working mode of the VIS6600T is abnormal because the initiator's FC port is connected to the optical switch.
D) In the working mode of VIS 6600T, the connection between the FC port of the target device and the optical switch is abnormal.
