Windows Server 2012 Validate Cluster Configuration
Word of caution: do not skip any error message that this wizard generates in the final report. Doing so would simply mean that our configuration going forward will be unsupported. We only need to run this wizard on either of the nodes.
To run the Validate Cluster Configuration Wizard:
1. Open the Failover Cluster Management console
2. Under the Management section, click the Validate a Configuration link. This will run the Validate a Configuration Wizard
3. In the Select Servers or a Cluster dialog box, enter the host names of the nodes that you want to add as members of your cluster and click Next.
i.e:- SQLCLST01, SQLCLST02
4. In the Testing Options dialog box, click Next to run all the necessary tests to validate whether or not the nodes are OK for clustering. If this is the first time to run the wizard, we must run all the tests for validation. For succeeding runs, especially when adding hardware like disk subsystems ot network cards on your cluster nodes, we can selectively choose which tests to run as long as we have initially validated our hardware by running all tests.
5. In the Confirmation dialog box, click next. This will run all the necessary validation tests.
In the Summary dialog box, verify that all the report returns successful.
Fail over Cluster Resource dependencies in sql server
When you install Microsoft SQL Server on a cluster as a SQL Server fail over cluster instance, a specific set of SQL Server resources that have dependencies on other resources in the cluster group are created.
Step 1: Right click on sql server more actions Show Dependency Report
