Hi guys,

Well, i have 2 SQL Server in Failover Cluster, Named db1 and db2. Yesterday i turn off the db2 for do a cold migration in my vsphere platform.

When i turn on the server db2 and try to change the resource from db1 to db2 i receive the following error: The disk associated with cluster disk resource 'Cluster Disk 6' could not be found. The expected signature of the disk was "Disk Sign". If the disk was removed from the server cluster, the resource should be deleted. If the disk was replaced, the resource must be deleted and created again in order to bring the disk online. If the disk has not been removed or replaced, it may be inaccessible at this time because it is reserved by another server cluster node.

I follow this steps: http://support.microsoft.com/kb/280425/en-us but when i try change the disk sign with diskpart tool i receive that the disk is in Read-Only, well i read and i found that the command attributes disk clear readonly can solve that. I did it and execute that command and the disk change to Read-Only: NO.

After that i execute again the command "uniqueid disk ID=[NEW SIGNATURE]" but in this test i receive the message "Diskpart has encountered an error: The requested resource is in use".

I need helps with that. I hope you can help me

Regards

Have you tried unpresenting the disk from host, reboot the node and follow the disk part steps?

 Some times there might be scsi reservations which prevent this.

Thanks, but the problem was in the vSphere Platform. I attach the wrong LUN.
