What you've shown is the normal configuraiton process for a new resource, where it goes through validation one node, followed by init on both nodes. The very last line shows the resource group APP-RG1 starting to come online on node 1. Your problem occurs after this.
What usually happens in this case is that the resource group tried to start on each node, failed, and then gave up (so it couldn't find a host node). This is because of one or more configuration problems, such as missing or incorrect HAStoragePlus resources, missing dependencies, host name issues, or network interface problems. Without seeing the error message(s) from the log and the configuration of the resource group and its resources, there's really nothing anyone can do to help you further.
