Cluster physical disk resource cannot be brought online because the associated disk could not be found
Confirm that the affected disk is available. For more information, see 'Reviewing hardware, connections, and configuration of a disk in cluster storage.' If the disk has failed, see 'Assigning a functioning disk to a clustered service or application if the previously assigned disk has failed.'
If you do not currently have Event Viewer open, see 'Opening Event Viewer and viewing events related to failover clustering.'
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.
To assign a functioning disk to a clustered service or application if the previously assigned disk has failed:
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 (it should be visible from one node but not multiple nodes). If it is visible to a node, 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 all the remaining steps and procedures.
Review the event log for any events that indicate problems with the disk. If an event provides information about the disk signature expected by the cluster, save this information and skip to the last step in this procedure.
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 click Storage.
In the center pane, find the disk resource whose configuration you want to check, and record the exact name of the resource for use in a later step.
Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
Type:
CLUSTER RESOURCE DiskResourceName /PRIV path\filename.TXT
For DiskResourceName, type the name of the disk resource, and for path\filename, type a path and a new filename of your choosing.
Locate the file you created in the previous step and open it. For a master boot record (MBR) disk, look in the file for DiskSignature. For a GPT disk, look in the file for DiskIdGuid.
Use the software for your storage to determine whether the signature of the disk matches either the DiskSignature or DiskIdGuid for the disk resource. If it does not, use the following procedure to repair the disk configuration.
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.
To determine whether the replacement disk that you want to use is already configured as a clustered disk in available storage, in the console tree, click Storage, and see whether the disk is listed under Available Storage.
In the console tree, click Services and Applications.
Perform this step only if the replacement disk is already configured as a disk in the clustered storage. Right-click the service or application that uses the disk that failed, click Add Storage, and add the replacement disk. Then, in the center pane, right-click the disk that failed, and then click the Remove from command.
Perform this step only if the replacement disk is not configured as a disk in the clustered storage. Expose a LUN to each node, but do not use Failover Cluster Management to add that LUN to the cluster. Then, with Services and Applications still selected, in the center pane, click the service or application that uses the failed disk, right-click the failed disk resource, click Properties and then, on the General tab, click Repair.
With the Repair button, you can assign a different disk to this service or application. The disk that you assign must be one that can be used for clustering but is not yet clustered.
Caution The Repair button does not recover data.
You can restore the data to the disk before or after using the Repair button.
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.
