Event ID 1574 — Failover Cluster Configuration Availability

  • Article

Applies To: Windows Server 2008 R2

The cluster configuration database contains essential information for the function of a failover cluster. A copy of the cluster configuration database is maintained on each node. If the quorum configuration for the cluster includes a witness disk, a copy of the cluster configuration database is also maintained on the witness disk. The Cluster service replicates the latest version of the cluster configuration database to all locations where it is stored.

Event Details

Message: The failover cluster database could not be unloaded. If restarting the cluster service does not fix the problem, please restart the machine.

Resolve

Check whether the node needs to be restarted

Sometimes when the node attempts to unload the cluster configuration database, the action does not fully complete. Try stopping and restarting the Cluster service. If this does not succeed, restart the operating system on the affected node.

To perform the following procedure, you must be a member of the local Administrators group on each clustered server, and the account you use must be a domain account, or you must have been delegated the equivalent authority.

To restart the Cluster service on a node:

  1. To open the failover cluster snap-in, click Start, click Administrative Tools, and then click Failover Cluster Management. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. In the Failover Cluster Management snap-in, if the cluster you want to manage is not displayed, in the console tree, right-click Failover Cluster Management, click Manage a Cluster, and then select or specify the cluster that you want.
  3. If the console tree is collapsed, expand the tree under the cluster you want to manage.
  4. Expand the console tree under Nodes.
  5. Right-click the node that you want to start and then click More Actions. If Stop Cluster Service is available, click it. Otherwise, skip to the next step.
  6. Right-click the node that you want to start, click More Actions, and then click Start Cluster Service.

Verify

To perform the following procedure, you must be a member of the local Administrators group on each clustered server, and the account you use must be a domain account, or you must have been delegated the equivalent authority.

To start the Cluster service on a node and confirm that it runs successfully:

  1. To open the failover cluster snap-in, click Start, click Administrative Tools, and then click Failover Cluster Management. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  2. In the Failover Cluster Management snap-in, if the cluster you want to manage is not displayed, in the console tree, right-click Failover Cluster Management, click Manage a Cluster, and then select or specify the cluster that you want.
  3. If the console tree is collapsed, expand the tree under the cluster you want to manage.
  4. In the console tree, select Nodes and expand the tree underneath it.
  5. In the center pane, view the status for each node. If the status is Up, the Cluster service is started on that node.
  6. To start the Cluster service on a node, right-click the node, click More Actions, and then click Start Cluster Service.
