Failed to failover disk resource after adding it, Registry Cleanup.

Hello Guys,

May I remove the keys under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ClusDisk\Parameters\AvailableDisks\  for disk signatures that already are on HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ClusDisk\Parameters\Signatures?

Using 2003R2.

Aren't the disks on "AvailableDisks" the ones that are not supposed to be part of the cluster, local disks?

The above text is my doubt right now as summarized as it gets, the following text is just for reference to future searches by other users and it is how i got here:

Thanks,

David

1 - Cluster Disk fails to failover. Happened after removing it from the cluster and readd it on another cluster group using other path , mount point.

2 - Checked the Cluster.log and found:

00001190.00001978::2014/02/21-15:09:01.137 INFO Physical Disk <Archive Storage 10>: [DiskArb] DisksOpenResourceFileHandle: Attaching to disk with signature da5203aa

3 - Noticed that Cluster nodes registry had some differences.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ClusDisk\Parameters\Signatures\

This key should have all the disk signatues inlcuded in the cluster.

4- Manually created the the signature key and devicename string value as explained on http://support.microsoft.com/kb/932465/en-us.

5- Disk was possible to be failed over.

6- Disk signature is also created on HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ClusDisk\Parameters\AvailableDisks\
