Problem and solution when port mapping on the USG6330 fails

If port mapping fails, check first whether the policy is correct and then view the session table information.

Problem and solution when some LUNs fail to be mapped when LUNs are mapped in batch
After LUN mappings are canceled in batch in a storage system, the LUNs generated on a host still exist. As a result, the storage system returns "Unmapped" with error code 0x05/0x25/0x00 due to I/Os sent using these LUNs. The interface protocol indicates that the error code performs a LUN switchover but the storage system uses a system lock for the LUN switchover. As a result, LUN mapping fails because no system lock can be obtained. To solve this problem, map the LUNs again. Then check whether the number of LUNs that are successfully mapped is correct.

Problem and solution when a KVM fails
Possible cause: The problem occurs when the power supply is unstable and has transient breaks after the reconstruction of the UPS. Solution: 1. Reinsert the USB cable. 2. If the problem persists, restart the KVM. 3. Replace the faulty keyboard and mouse or the KVM. 4. If the problem persists, restart the SVP.

Problem and solution when the electrical port of the firewall is down
What if the electrical port of the USG is not Up? 1. Check whether the faulty port is disabled. If yes, run the undo shutdown command to enable the port. 2. Remove the network cable: -Check whether the gold pin of the interface is bent or deviates. -Check whether the network cable is disconnected or damaged. -Check the type of the network cable. A GE electrical port fails to go Up if a network cable lower than category 5 cable is used. -A GE electrical interface may fail to go Up if some wires among the four wire pairs in the network cable are damaged. 3. Auto-negotiation shall be configured on both ports, and the rates and duplex modes on both ports shall be the same. 4. Incorrect MDI setting: -The current device can automatically identify straight cables or crossover cables, and MDI is usually not required.

Problem and solution when the optical port of the firewall is down
What if the optical port of the USG is not Up? 1. The negotiation modes, rates, and duplex modes on both ends shall be the same. 2. Check whether optical fibers and optical transceivers are correctly used. -A multi-mode fiber can be used with a single-mode optical transceiver if the transmission distance is short. -A single-mode optical fiber can only be used with a single-mode optical transceiver. -Check whether the optical port and optical transceivers are incorrectly used together. For example, 100M optical ports are used together with 1000M optical transceivers. -Check whether the optical transceiver is authenticated. -Generally, a single-mode optical fiber is yellow, and a multi-mode optical fiber is orange. 3. Run the display interface xx command to check whether the wavelengths of the connected optical transceivers are the same and whether the distances are proper. 4. Run the display interface xx verbose command to check whether the receive or transit power of the optical ports is within the allowed range. 5. Connect the head and tail of a fiber to an optical transceiver to check whether the port can go Up. 6. If the fault persists, consider replacing the optical transceiver and optical fiber.

Problem and solution when the heartbeat interfaces of the firewalls fail to be directly connected
Troubleshoot as follows: 1. Check whether the cable is properly connected. 2. Check whether the interface has been added to the security zone. 3. Check whether service-manage ping permit is configured under the interface.
