How Do I Handle a BMS Network Failure?
- Run the following command to check whether the BMS network ports have been bonded:
Figure 1 Checking for bond
If no bonding information is obtained, the BMS network ports are not bonded. Contact technical support.
- Run the following command to check whether the BMS route information is correct:
Figure 2 Checking BMS route information
Check whether the default route (with a destination of 0.0.0.0/0) exists.
Figure 3 Checking the default route
Check whether a route to 169.254.169.254 exists.
Figure 4 Checking the route for IP address range 169.254.169.254
If the required routes are not there, contact technical support.
- If BMSs in a VPC cannot communicate with each other or a BMS with an EIP bound cannot access the Internet, rectify the failure based on the related FAQ.
- If the failure cannot be rectified after you perform these operations, contact technical support.
Obtain the VPC and BMS information on the management console and provide the technical support engineer with the following information.
