Validating cluster resource ip address

Issue 1: SQL Server service accounts are unable to contact a domain controller.

Resolution 1: Check your event logs for signs of networking issues such as adapter failures or DNS problems. Issue 2: SQL Server service account passwords are not identical on all cluster nodes, or the node does not restart a SQL Server service that has migrated from a failed node.

Resolution 3: To connect using Named Pipes, create an alias using the SQL Server Configuration Manager to connect to the appropriate computer.

For example, if you have a cluster with two nodes (Node A and Node B), and a failover cluster instance (Virtsql) with a default instance, you can connect to the server that has the Network Name resource offline using the following steps: Issue: An orphan registry key in [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL. X registry hive is not currently in use, and then delete the cluster key.

Issue 1: Firmware or drivers are not updated on all nodes.

The first diagnostic step is to run a fresh cluster validation check.

For details on validation, see Failover Cluster Step-by-Step Guide: Validating Hardware for a Failover Cluster.

If the entire storage category was excluded from being tested, then this prompt is not displayed.

This will enable cluster validation with no downtime.

This can be completed without any interruption of service as it does not affect any online cluster resources.
