Setting a dependency between the service groups
The RVG service group must be online on both the primary and secondary zones. However, if a failover occurs from one node to another within the same zone, the RVG service group must fail over along with the application service group.
To ensure that the SQL Server service group and the RVG service group fail over and switch together, set up an online local hard dependency from the RVG service group to the SQL Server service group.
The SQL Server service group (for example, INST1_SG) is dependent on the replication service group (for example, INST1_RVG_GRP).
To set up an online local hard dependency
- From VCS Cluster Explorer, in the left pane, select the cluster (MYCLUSTER).
- In the right pane, select the Service Groups tab.
- Click the Link button to create a dependency between service groups.
- Click the application service group (parent service group).
For example, click the SQL Server service group INST1_ SG.
- Click the RVG service group (the child resource).
For example, click the RVG service group INST1_RVG_SG.
- In the Link Service Groups window, specify the following:
Select the Relationship of online local.
Select the Dependency Type of hard.
Click OK.
