we want to create a very simple cluster with only two nodes. They are on different geographically sites. The only connection is trhough a 1 GB ethernet network. They do not share any disks/VGs neither a unique IP service. They only run some RGs which start/stop scripts on any on the nodes. I mean, let's see an example.
If NODE1 is gone, RG1 and RG2 starts on NODE2.
This RGS only run some start/stops scripts to our application. As you see it's very simple setup.
But, the only way, AFAIK, to create only one TCPIP ether type network (no disk heartbeat, no non-TCP network or even GLVM-XD-DATA/IP network) between the nodes, but we also know it's recommended to have more than ONE network between nodes.
So, the question would be:
Do you think is possible to add another network (to the existing ether network type) between the nodes?
What will do powerHA with RGs if this ethernet network is down and NODE1 and NODE2 are Up?
