Using the Information Interfaces

[Support for Failover Cluster Administrator extension DLLs was removed in Windows Server 2008.]

Your implementations of the Failover Cluster Administrator extension interfaces can use the Failover Cluster Administrator information interfaces to gather information. Note the following restrictions:

• IGetClusterUIInfo, IGetClusterObjectInfo, and IGetClusterDataInfo can be called by any extension DLL.
• IGetClusterGroupInfo should be called only by extension DLLs that are extending groups.
• IGetClusterNetworkInfo should be called only by extension DLLs that are extending networks.
• IGetClusterNetInterfaceInfo should be called only by extension DLLs that are extending network interfaces.
• IGetClusterNodeInfo should be called only by extension DLLs that are extending nodes.
• IGetClusterResourceInfo should be called only by extension DLLs that are extending resources.
