3.1.4.2.158 ApiRemoveClusterGroupDependency (Opnum 176)

The ApiRemoveClusterGroupDependency method<145> instructs the server to remove the dependency relation (section 3.1.1.1.2) that exists from the Cluster Group that is identified by hGroup to the Cluster Group that is identified by hDependsOn. For successful completion of the method, the server MUST remove the dependency from the nonvolatile cluster state.

The server MUST accept an ApiRemoveClusterGroupDependency request only if its protocol server state is read/write, as specified in section 3.1.1.

The server MUST require that the access level associated with the hGroup context handle is "All" and that the access level associated with the hDependsOn context handle is "All" (section 3.1.4).

 error_status_t
 ApiRemoveClusterGroupDependency (
   [ in ] HGROUP_RPC hGroup,
   [ in ] HGROUP_RPC hDependsOn,
   [ out ] error_status_t *rpc_status
 );

hGroup: An HGROUP_RPC (section 2.2.1.3) context handle that was obtained in a previous ApiOpenGroup (section 3.1.4.2.42), ApiOpenGroupEx (section 3.1.4.2.118), or ApiCreateGroup (section 3.1.4.2.43) method call.

hDependsOn: An HGROUP_RPC context handle that was obtained in a previous ApiOpenGroup or ApiOpenGroupEx method call.

rpc_status: A 32-bit integer used to indicate success or failure. The RPC runtime MUST indicate by writing to this parameter whether the runtime succeeded in executing this method on the server. The encoding of the value passed in this parameter MUST conform to encoding for comm_status and fault_status, as specified in Appendix E of [C706].

Return Values: The method MUST return the following error codes for the specified conditions.

Return value/code	Description
0x00000000 ERROR_SUCCESS	Success.
0x00000006 ERROR_INVALID_HANDLE	The data that is pointed to by either the hGroup parameter or the hDependsOn parameter does not represent a valid HGROUP_RPC context handle.
0x00000428 ERROR_EXCEPTION_IN_SERVICE	An exception occurred in the service when handling the control request.
0x00001394 ERROR_GROUP_NOT_AVAILABLE	The group represented by the hGroup parameter no longer exists in the nonvolatile cluster state.
0x000013D1 ERROR_CLUSTER_NODE_SHUTTING_DOWN	The cluster node is shutting down.

For any other condition, this method MUST return a value that is not one of the values listed in the preceding table. The client MUST behave in one consistent, identical manner for all values that are not listed in the preceding table. The client SHOULD treat errors specified in section 3.2.4.6 as recoverable errors, and initiate the reconnect procedure as specified in section 3.2.4.6.
