Notes

To perform this procedure, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security best practice, consider using Run as to perform this procedure.
To open Cluster Administrator, click Start, click Control Panel, double-click Administrative Tools, and then double-click Cluster Administrator.
A possible owner is a node that is capable of running a resource.
If you want to make a group capable of failing over, it must have more than one possible owner.
If a resource has no possible owners, it will not come online. This can be useful if you want to keep a resource offline but you do not want to delete it and lose its configuration settings.
If the resource DLL for a particular resource type is not available on some nodes, these nodes are automatically removed from the possible owners list for all the resources of this type.

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
