We are running a Windows Server 2003 Cluster with several SQL Server 2005 instances. I know want to move two disk resources from a SQL instance which is being turned down. I tested the process and the move into another cluster group works but there are some folders on one of the disks I am not sure about what I should do with them. Looks like they contain some hotfixes files. Can I simply delete them or will that somehow hurt us in the long run?
