In the embodiment of the application, the diagnosis of the internal link of the FC card can be realized in a further mode, and the method comprises the following steps:

Test environment: selecting one of the ports of the FC card, inserting the optical module, connecting the receiving end and the transmitting end of the optical module through an optical fiber, enabling data to enter the receiving end of the optical module from the transmitting end of the optical module through the optical fiber and enter the port of the FC card, and realizing self-loopback of the ports, wherein FIG. 6 is an optional port self-loopback connection schematic diagram according to an embodiment of the application, and the data transmitting port and the data receiving port included in the port 4 are connected in a self-loopback manner through the optical fiber as shown in FIG. 6. The specific test process is as follows:

1) Connecting the head fiber and the tail fiber of an optical fiber to an optical module of an FC card test port, wherein the test port of the FC card is in a diagnosis mode;

2) Inquiring an FC card chip manual, acquiring a register value of an FC card sending message, and enabling the FC card chip to start sending a data message by operating the register;

3) The data packet sent by the chip is forwarded to the sending end of the optical module through the internal link of the FC card, and the sending end of the optical module is transmitted back to the receiving end of the optical module through the optical fiber, so that the self-loop-back of the port is realized. The optical module receiving end transmits the received data packet back to the chip through the FC card internal link;

4) At this time, a register of the number of messages received and sent by the FC card is obtained, and whether the data packet received by the FC card is equal to the sent data packet is read. If the data message received by the FC card is 0, the internal forwarding link is not communicated, and the link is abnormal; if the number of the sending messages and the number of the receiving messages of the FC card are not equal, the data forwarded inside the FC card loses the packet, and the link quality is problematic; if the data message sent by the FC card is equal to the number of the received messages, the link is normal.

5) By using the method, the self-loopback test of long-time message forwarding can be performed, and the link stability of forwarding data inside the FC card can be tested.

Through the two modes, whether internal data forwarding of the current FC card is normal or not can be checked, and whether the FIO bandwidth is normal or not is checked, so that the health diagnosis standard of the FC card is increased, and the quality of components is improved.

The application has at least the following advantages:

1. Vmdisk is simulated in the equipment memory by utilizing scst technology, and is used as a target storage target unit for FC card test, scst drive and FC card drive are combined, and a test network port is mapped to the disk equipment, so that a read-write and data forwarding mode of the FC card is realized.

2. The FC card port self-loop-back link detection is carried out, the receiving and transmitting ends of the optical modules of one port of the FC card are connected by utilizing the optical fiber, data are sent through the FC card chip, the data are forwarded inside the FC card to the transmitting end of the optical module, and the data packet is forwarded to the receiving end of the optical module through the optical fiber, so that the port self-loop-back is realized. By the method, whether the internal data forwarding of the FC card is normal or not can be detected, and diagnosis of the internal data forwarding link of the FC card is realized.

3. The method comprises the steps of performing loop-back link detection on the double ports of the FC card, connecting optical modules of two test ports by using optical fibers, introducing SCST (serial bus interface) drive, mounting the ports of the FC card on a disk device, performing read-write test on the device mounted on the test ports of the FC card by using a fio detection tool, and detecting whether the performance forwarding of the FC card is normal or not, so that port link diagnosis can be realized.
