http://support.microsoft.com/kb/290991/en-us

I need to remove sql resources and groups ( 1 sql group).What resources do i need to remove? Under sqlgroup we have disk resources and sqlagent,sqlserver, Sql network name, sql ip address, sql search ,some flieshares resources..
1. Do i need to remove resources from Resources in cluadmin and then delete group?
2. Do i need to delete disk resources(Disk e:, diskF etc) also?
2. When I right click sql group, the delete option is grayed out for me. My login has all admin rights in both the nodes.
Any one pls let me know ASAP?
Thanks in Advance
