Event ID 1135 — Cluster Service Startup

  • Article

Applies To: Windows Server 2008

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: 1135
Source: Microsoft-Windows-FailoverClustering
Version: 6.0
Symbolic Name: EVENT_NODE_DOWN
Message: Cluster node '%1' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.

Resolve

Check network hardware and configuration

If you do not currently have Event Viewer open, see "Opening Event Viewer and viewing events related to failover clustering." After reviewing event messages, choose actions that apply to your situation:

  • Run the Validate a Configuration Wizard, selecting only the network and inventory tests. For more information, see "Using the Validate a Configuration Wizard to review the network configuration."
  • Check the system event log for hardware or software errors related to the network adapters on this node.
  • Check the network adapter, cables, and network configuration for the networks that connect the nodes.
  • Check hubs, switches, or bridges in the networks that connect the nodes.

To perform the following procedures, 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.

Using the Validate a Configuration Wizard to review the network configuration

To use the Validate a Configuration Wizard to review the network configuration:

  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, in the console tree, make sure Failover Cluster Management is selected. Then under Management, click Validate a Configuration.
  3. Follow the instructions in the wizard to specify the cluster you want to test.
  4. On the Testing Options page, select Run only tests I select.
  5. On the Test Selection page, clear all check boxes except those for the Network tests.
  6. Follow the instructions in the wizard to run the tests.
  7. On the Summary page, click View Report.

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.
