WSFC cluster service is offline
WSFC Cluster State
WSFC cluster service is offline.
Instance of SQL Server
This policy checks the state of the Windows Server Failover Cluster (WSFC). The policy is in an unhealthy state and an alert is raised when the WSFC cluster is offline or in the forced quorum state. All availability groups hosted within this cluster are offline or a disaster recovery action is required.
The policy state is healthy when the cluster state is in the normal quorum.
For this release of SQL Server 2016, information about possible causes and solutions is located at WSFC cluster service is offline on the TechNet Wiki.
This issue can be caused by a cluster service issue or by the loss of the quorum in the cluster.
Use the Cluster Administrator tool to perform the forced quorum or disaster recovery workflow. If you cannot resolve the issue by performing the forced quorum or disaster recovery, contact your cluster administrator to help resolve this issue.
