Instances may fail to join the cluster because of problems with the private networks used to support interconnect communication. If one or more instances in the cluster fail to start:
Examine the error logs for those instances that could not join to see if there are any messages indicating the network communication has failed. The error logs are located in $SYBASE/$SYBASE_ASE/install/instance_log
Verify that all private networks used on the nodes used by the cluster are accessible from all nodes in the cluster. Use the ping utility to do this. See “Verifying the cluster environment”.
Check for errors in the UAF agent logs.
