Issue
After registering the CM Cluster, the cluster start fails due to inability to communicate with the master node.
The CM2 log shows a "No route to host" error, indicating that the master node cannot be accessed.
(Issue where start fails due to inability to communicate with the master node after adding cluster to cm on nodes other than the master node)
- When checking the cm2 log, [ERROR] connect error: No route to host occurs, and logs show that connection to cm1 (Master node) is not possible.
(This can be confirmed in the trace_cm.log file located at the path specified by the CM_LOG_DEST parameter in the cm tip file)

Cause
The start failure occurs due to inability to communicate with the master node over the interconnect network.
Solutions
- Check the firewall and access control solutions on the master node server.
- Verify that interconnect network communication between the two nodes is functioning properly.
NoteEven if ping is successful, this issue may still occur, so it is necessary to verify the ports using telnet.
