Thank You

Hi Darshan,

You can configure two types of SG dependencies in this scenario:

1) online remote local

2) online remote firm

There are slight differences in behavior depending on whether the service groups are failover or parallel. You can find the details in Veritas Cluster Server Administrator's Guide.

If the application should not start until the database has started, then you should use dependences as described by Setu.  If the application and database can start independently, then you should use System Limits and service group prerequistes, so for instance:

For each system set System attribute Limits = {appdb=1} (example hasys -modify node1 Limits appdb 1)

For your db and app service group set group attribute Prerequisites = {appdb=1} (example hagrp -modify db-sg Prerequistes appdb 1)

How are the SystemList going to be setup for Application and Database? Also are they Failover/Parallel service group?
