Server 2008 Cluster Fail-over Errors

HI Team

Can you please provide some guidance around the following:

the weekend I had to patch some server 2008 clustered servers, on one of the nodes we got the below error:


Ownership of cluster disk 'Cluster Disk 8' has been unexpectedly lost by this node. Run the Validate a Configuration wizard to check your storage configuration.
Cluster resource 'Cluster Disk 8' in clustered service or application 'IGMSCLU3006B' failed.

Due to the above, one of the SQL instances was not available for about 1 hour between 8h15-9h15am,

The business owner wants to understand what the cause of these issues/errors was and prevent them from happening again, can you please assist me with coming up with something plausible to explain to them?

I've attached the cluster events for time period the issue started,

This might be a network issue or something related to your storage solution. How many disks the cluster has? Only one got the issue?
Do you have a network and a storage team? If so, contact them and request more info on this issue.
Just added more topics to call Experts in other areas to help.
