HI Mohan,


First off, thanks for your reply!



We have yet to try your suggestions.



We are in the middle of adding a new application to be managed by osaf.

We're planning to create a new SG to manage this app, so that if this app ever 
needs to be taken out-of-service (locked), we want to do so without bringing 
down the current apps that are already being managed by osaf.  At the same 
time, we want all the apps to be running with their Active HA state on the same 
node.

So, if one fails over, we want all the apps to fail over.



Thus, the reason for my question.

Basically, we wanted to know if this is feasible and it sounds like it is.



Thanks!

-David

Hi Dave,

Good afternoon!

You case description matches with Node failover.



1. Will node failover work for you? You can set saAmfNodeSuFailoverMax to 0 and 
let escalation happen.

Or

2. you can set recommended recovery action as node failover/switchover?

Or

3. call a common cleanup script to kill components of each SU and let everyone 
get SU failover triggered?





Thanks & Best Regards

Subject: [users] SU failover



Hi all,



Does OpenSAF provide a mechanism to have the SUs from different SGs (running 
with 2N redundancy) to all failover to their Standby if one of the SUs fail?



Basically, we want to manage several services separately but at the same time, 
keep their Active SU co-located on the same node.

So if one service needs to failover, the other Active SUs automatically 
failover too.





Regards,

David
