FAQs
- Question 1: What should I do if I fail to configure DR for a DR instance?
Check whether the security groups of the production center and DR center allow traffic from the ports of the VPC subnets each other. If a VPN connection is used, check whether the VPCs are connected as instructed in Method 2: Using VPN to Connect VPCs in Different Regions.
- Question 2: Why did the system display a message indicating that there is a route conflict in the current VPC when I use Cloud Connect to connect VPCs?
Rectify the fault by referring to What Can I Do If There Is a Route Conflict When I Load a Network Instance to a Cloud Connection?
