No binding virtualIP to a clustered node for a generic app service

Latest response

I have 2 nodes cluster as follow:
- node1: 10.20.30.100 installed RHEL 7.2 pacemaker corosync myapp /etc/init.d/LA_myapp
- node2: 10.20.30.101 installed RHEL 7.2 pacemaker corosync myapp /etc/init.d/LA_myapp
- create and configure cluster: hacluster
- create resource group: myRG
- create resources as follow:

pcs resource create cc_fs Filesystem device="/dev/ccvg/cclv1" directory="/mnt/ccstor" fstype="ext4" --group myRG
pcs resource create VirtualIP IPaddr2 ip=10.20.30.105 cidr_netmask=24 --group myRG
pcs resource create mySvc LSB:LA_myapp --group myRG
I have several functional modules which run based on tomcat, they are supposed to launch by https://node_IP/appName from internet browser.
When I create and start "myapp" above, it should register all of my app modules using https://VirtualIP/appName.

My problem is:
1. I got an unknown host name error for "VirtualIP" for registering above.
2. No bind from "VirtualIP" to the running node.
Please help me out of these trouble.
