Event ID 1035 — Cluster Storage Functionality

Applies To: Windows Server 2008

In a failover cluster, most clustered services or applications use at least one disk, also called a disk resource, that you assign when you configure the clustered service or application. Clients can use the clustered service or application only when the disk is functioning correctly.

Event Details

Product: Windows Operating System
ID: 1035
Source: Microsoft-Windows-FailoverClustering
Version: 6.0
Symbolic Name: RES_DISK_MOUNT_FAILED
Message: While disk resource '%1' was being brought online, access to one or more volumes failed with error '%2'. Run the Validate a Configuration wizard to check your storage configuration. Optionally you may want to run Chkdsk to verify the integrity of all volumes on this disk.

Review presentation of the disks to the cluster nodes

Check the underlying storage hardware and confirm that the device is being presented correctly to the cluster nodes. For more information, see "Reviewing the presentation of disks to the nodes."

If you do not currently have Event Viewer open, see "Opening Event Viewer and viewing events related to failover clustering." If the event contains an error code that you have not yet looked up, see "Finding more information about error codes that some event messages contain."

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.

Reviewing the presentation of disks to the nodes

To review the presentation of disks to the nodes:

  1. On each node in the cluster, open Disk Management (which is in Server Manager under Storage) and see if the disk is visible from one of the nodes. If so, continue to the next step. If it is not visible from any node, still in Disk Management on a node, right-click any volume, click Properties, and then click the Hardware tab. Click the listed disks or LUNs to see if all expected disks or LUNs appear. If they do not, check cables, multi-path software, and the storage device, and correct any issues that are preventing one or more disks or LUNs from appearing. If this corrects the overall problem, skip the remaining steps.

  2. Review the event log for any events that indicate problems with the disk.

  3. 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.

  4. In the Failover Cluster Management snap-in, in the console tree, make sure Failover Cluster Management is selected and then, under Management, click Validate a Configuration.

  5. Follow the instructions in the wizard to specify the cluster you want to test.

  6. On the Testing Options page, select Run only tests I select.

  7. On the Test Selection page, clear the check boxes for Network and System Configuration. This leaves only the tests for Storage and Inventory. You can run all these tests, or you can select only the specific tests that appear relevant to your situation.

    Important   If a clustered service or application is using a disk when you start the wizard, the wizard will prompt you about whether to take that clustered service or application offline for the purposes of testing. If you choose to take a clustered service or application offline, it will remain offline until the tests finish.

  8. Follow the instructions in the wizard to run the tests.

  9. On the Summary page, click View Report.

  10. If the preceding steps have not provided enough information to correct the issue, optionally, try running Chkdsk on the disk to verify the integrity of the volumes on the disk.

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.

Finding more information about the error codes that some event messages contain

To find more information about the error codes that some event messages contain:

  1. View the event, and note the error code.
  2. Look up more information about the error code in one of two ways:

Verify

Confirm that the disk resource can come online. If there have been recent problems with writing to the disk, it can be appropriate to monitor event logs and monitor the function of the corresponding clustered service or application, to confirm that the problems have been resolved.

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.

Confirming that a disk resource can come online

To confirm that a disk resource can come online:

  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 expand Services and Applications.
  4. In the console tree, click a clustered service or application.
  5. In the center pane, expand the listing for the disk resource. View the status of the resource.
  6. If a disk resource is offline, to bring it online, right-click the resource and then click Bring this resource online.

To perform a quick check on the status of a resource, you can run the following command.

Using a command to check the status of a resource in a failover cluster

To use a command to check the status of a resource in a failover cluster:

  1. On a node in the cluster, click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

  2. Type:

    CLUSTER RESOURCE ResourceName /STATUS

    If you run the preceding command without specifying a resource name, status is displayed for all resources in the cluster.
