I have a requirement where I have two application resources(rs-app-db-004 and rs-app-rm-004). in the same service group but I want to make one as Non-Critical. Please be noted that both the applications share the same mount point.
My requirement is that if the Non-Critical application( rs-app-db-004) goes down, then the service group should be be partially Online and no failover should take place. The critical application should continue to function And if the Critical application(rs-app-rm-004) goes down then irrespective whether Non-Critical application is faulted or Onilne, the whole service group should failover to the other node. Currently both the applictaions are Critical.
Do i also need to make Non-critical resource dependent on the the Critical application? I am not sure on this as theoritically failure of critical application should failover the whole service group.
Also I want to understand is making this resource rs-app-db-004 non critical would have any implications or not during failover or elsewhere? If yes then request you to update me on that.
Is this supported in my current version? if not then is there any patch to address this
- The version of VERITAS installed is 5.1SP1
I read one of the link that doing so can have implication.

The dependency of the resources in the service group is shown below.
