Handling Process
1. Add a gateway device to the onsite network.
2. Perform the failover again. The problem is solved.
Root Cause
1. The onsite switch is a layer-2 switch. Although it ensures the normal communication between two nodes in the cluster, it works at the data link layer and cannot serve as a gateway device.
2. After the faulty node is recovered, the ping 172.30.192.1 command is executed on the node to determine whether it is recovered. Because no gateway device exists on the network, the node cannot obtain the recovery information. Therefore, this node cannot enter the Ready state.
Suggestions
When you configure the VTL6900 cluster, determine whether the onsite network meets cluster network requirements and whether gateway devices exist on the network. If no gateway device exists on the onsite network, communicate with customers at the site to solve the problem.
