Event ID 1568 — 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.
|Product:||Windows Operating System|
|Message:||Cluster disk resource '%1' found the disk identifier to be stale. This may be expected if a restore operation was just performed or if this cluster uses replicated storage. The DiskSignature or DiskUniqueIds property for the disk resource has been corrected.|
Confirm disk identifier
After the cluster software automatically corrects the DiskSignature or DiskUniqueIds property (after a disk has been restored, or in a cluster that uses replicated storage), no action is necessary. However, it can be appropriate to check the storage configuration.
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.
Opening Event Viewer and viewing events related to failover clustering
To open Event Viewer and view events related to failover clustering:
- 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.
- In the console tree, expand Diagnostics, expand Event Viewer, expand Windows Logs, and then click System.
- 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.
- To sort the displayed events by date and time, in the center pane, click the Date and Time column heading.
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:
- 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.
- 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.
- If the console tree is collapsed, expand the tree under the cluster you want to manage, and then expand Services and Applications.
- In the console tree, click a clustered service or application.
- In the center pane, expand the listing for the disk resource. View the status of the resource.
- 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:
On a node in the cluster, click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
CLUSTER RESOURCE ResourceName /STATUS
If you run the preceding command without specifying a resource name, status is displayed for all resources in the cluster.
