Description	Clustered disk with ID '%2' was not released by the Partition Manager while destroying the cluster. The error code was '%1'. Restarting the machine will ensure the disk is released by the Partition Manager.
Event Information	According to Microsoft : Cause : This event is logged when clustered disk was not released by the Partition Manager while destroying the cluster. Resolution : Confirm that the action of destroying a cluster was fully completed An operation that was part of destroying the cluster did not succeed. Try restarting the server to see if this resolves the error. If not, use commands to force cleanup on former cluster nodes, and to force the clearing of persistent reservations on disks formerly used by the cluster. These commands help ensure that the cluster configuration has been completely removed. 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 procedures, you must be a member of the local Administrators group on the server, or you must have been delegated the equivalent authority. Forcing cleanup on a former cluster node after the cluster has been destroyed To force cleanup on a former cluster node after the cluster has been destroyed: On the former cluster node that you want to clean up, open an elevated Command Prompt window. To do this, click Start , point to All Programs , click Accessories , right-click Command Prompt , and then click Run as administrator . Type: CLUSTER NODE /FORCECLEANUP Forcing the clearing of persistent reservations on a disk formerly used by the cluster To force the clearing of persistent reservations on a disk formerly used by the cluster: On one or more nodes in the cluster, open Disk Management (which is in Server Manager under Storage ) and see if any disks formerly used by the cluster are visible from one of the nodes. If they are, note the node and the number that Disk Management uses to refer to that disk. On a node from which a formerly-clustered disk is visible in Disk Management, open an elevated Command Prompt window. To do this, click Start , point to All Programs , click Accessories , right-click Command Prompt , and then click Run as administrator . Type: CLUSTER NODE /CLEARPR:disknumber where disknumber is the number of the disk as it appeared in Disk Management. 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 .

Click Start , point to All Programs , click Accessories , click Command Prompt , and then type: NET HELPMSG errorcode Verify : To verify the cleanup of a cluster node, you can rerun the command for forcing cleanup and confirm that it completes successfully. To perform the following procedure, you must be a member of the local Administrators group on the server, or you must have been delegated the equivalent authority. To run the command that forces cleanup of a former cluster node: On the former cluster node on which you want to confirm cleanup, open an elevated Command Prompt window.
