Event ID 1247 — Cluster Service Startup

  • Article

Applies To: Windows Server 2008 R2

The Cluster service is the essential software component that controls all aspects of failover cluster operation and manages the cluster configuration database. If the Cluster service fails to start on a failover cluster node, the node cannot function as part of the cluster.

Event Details

Product: Windows Operating System
ID: 1247
Source: Microsoft-Windows-FailoverClustering
Version: 6.1
Symbolic Name: CLUSTER_EVENT_INVALID_SERVICE_SID_TYPE
Message: The Security Identifier (SID) type for the cluster service is configured as '%1' but the expected SID type is 'Unrestricted'. The cluster service is automatically modifying its SID type configuration with the Service Control Manager (SCM) and will restart in order for this change to take effect.

Resolve

Confirm success of security ID configuration change

Sometimes, before the Cluster service can function, it must modify its security ID (SID) type configuration with the Service Controller Manager and then restart for the change to take effect. No action is necessary, but monitor the status of the node to ensure that it comes up as expected.

If you do not currently have Event Viewer open, see "Opening Event Viewer and viewing events related to failover clustering."

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 open Event Viewer and view events related to failover clustering:

  1. If Server Manager is not already open, click Start, click Administrative Tools, and then click Server Manager. 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 console tree, expand Diagnostics, expand Event Viewer, expand Windows Logs, and then click System.
  3. To filter the events so that only events with a Source of FailoverClustering are shown, in the Actions pane, click Filter Current Log. On the Filter tab, in the Event sources box, select FailoverClustering. Select other options as appropriate, and then click OK.
  4. To sort the displayed events by date and time, in the center pane, click the Date and Time column heading.

Verify

To perform this 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.

Verifying that the Cluster service is started on all the nodes in a failover cluster

To verify that the Cluster service is started on all the nodes in a failover cluster:

  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, and then click Nodes.
  4. View the status for each node. If a node is Up, the Cluster service is started on that node.

Another way to check whether the Cluster service is started is to run a command on a node in the cluster.

Using a command to check whether the Cluster service is started on a node

To use a command to check whether the Cluster service is started on a node:

  1. On the node that you are checking, click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

  2. Type:

    CLUSTER NODE /STATUS

    If the node status is Up, the Cluster service is started on that node.
