5. The method according to claim 1, wherein the determining, by the storage side, whether a processing flag exists in the port information in response to receiving the port information returned by the host fibre channel port, comprises:
and the storage end judges whether the port information returned by the host fiber channel port is received within the effective time.
6. A computer device, comprising:
at least one processor; and
a memory storing computer instructions executable on the processor, the instructions when executed by the processor implementing the steps of:
the host end creates a host unique identifier of a host optical fiber channel port, writes the host unique identifier into port information of the host optical fiber channel port, and adds attribute information of the optical fiber channel port and host operating system identifier information into the port information;
in response to monitoring that the state of a storage fiber channel port is changed into online for the first time and/or host port information refreshing time is triggered, a storage end constructs a port request message according to the unique identifier of the port information request message and the storage unique identifier and sends the port request message to all host fiber channel ports;
in response to receiving port information returned by the host fiber channel port, the storage terminal judges whether a port information processing mark exists in the port information; and
in response to the absence of the port information processing mark, the storage end attributing the host fibre channel port to the corresponding host based on the host unique identifier and writing the processing mark in the port information corresponding to the host fibre channel port.
7. The computer device of claim 6, wherein the steps further comprise:
and creating a storage unique identifier of the storage fiber channel port and writing the storage unique identifier into a port request message of the storage fiber channel port.
8. The computer device of claim 7, wherein the steps further comprise:
in response to the port request message, the host fiber channel port judges whether other host fiber channel ports receive the same port request message according to the port information; and
and triggering the port information broadcast operation in response to the condition that no other host fiber channel port receives the same port request message.
9. The computer device of claim 6, wherein the steps further comprise:
monitoring the states of all host optical fiber channel ports, responding to the first time that the host optical fiber channel ports are changed into an online state, and carrying out port information broadcasting by the host optical fiber channel ports.
10. A computer-readable storage medium, in which a computer program is stored which, when being executed by a processor, carries out the steps of the method according to any one of claims 1 to 5.
