The CLUSCTL_CLUSTER_NOTIFY_INFRASTRUCTURE_SOFS_CHANGED cluster control code<222> instructs the server to inform every active node in the cluster that SOFS changed.

Protocol version 2.0 servers do not support this control and MUST fail this method by using error code 0x00000001 (ERROR_INVALID_FUNCTION).

The client SHOULD set the nInBufferSize parameter to zero, indicating that there is no input data associated with this control. The server MUST ignore any input data specified by the client.

After successful completion of the method, the server SHOULD NOT write any data to the buffer that is designated by lpOutBuffer.

The server SHOULD accept a CLUSCTL_CLUSTER_NOTIFY_INFRASTRUCTURE_SOFS_CHANGED cluster control code request if its protocol server state is in the read/write state, as specified in section 3.1.1.
