Hi all, I have a 2-node system (SC-1, SC-2) that requires an alias IP (points to the active application that's also runs on these nodes). If SC-1 is up and running, as well as the application, the alias IP has been added to eth0.
When an application si-swap is performed, the application deletes the alias IP on SC-1. Likewise, when it goes active on SC-2, it will add the alias IP to SC-2's device (eth0). The issue I have, is when SC-2 comes up, I found that the connection between SC-2's TCP port 6700 is to SC-1's alias IP. So, when the si-swap is performed, the alias IP gets deleted as part of the application being stopped on SC-1. As a result, the connection between the 2 nodes is gone: osafdtmd generates a log stating a loss of connection. End result is split-brain. Now, if SC-2 comes up without the application enabled on SC-1, the alias IP has yet to be added, so the connection between the nodes' port 6700 is actually with the node's IP address. I can enforce this on the initial setup, but if one of the opensaf processes on a nodes goes for a restart or if a node reboots, since the alias IP exists, upon coming up, the newly started opensaf will have a connection to the alias IP. Long story short, is there anything within the DTM area that could help me in preventing opensaf sending outbound messages over the alias IP instead of the node IP?
