Dependence between Service Groups in Disaster Recovery solution.
Hi,
I´m trying to implement a Disaster Recovery solution on a "two server per site" scenario but I´m having some problems.... I´ve created a service group (SG) for each server (database and middleware) and I don´t know how to set the dependence between these SG to make the entire cluster failover to the secondary site in the case of any fault on the primary. I´ve tried linking the SG´s with an "Online Remote Firm" dependence and it worked well when the fault occurs in the child-SG, but if the fault occurs in the parent-SG the cluster doesn´t failover to the entire site, in fact the child-SG never comes offline. Is there any way to do this?? I think that the "hard" rigidity dependence should work well but unfortunately it only exists in a local relationship betweet SG´s and mine are stored in separate servers.
Thanks!
