The CprepDiskStopDefense method stops any implementation-specific method of maintaining ownership of a disk.
In order to perform a "stop defense", the following conditions MUST be met:
The Ownership value of the designated disk MUST be OwnedByThisServer, as a result of a previous successful CprepDiskPRArbitrate (section 3.2.4.15) call.
The affected ClusPrepDisk.OnlineState has to be equal to Not Online.
Both the CprepDiskPRArbitrate and CprepDiskOffline (section 3.2.4.12) methods MUST be called before CprepDiskStopDefense.
HRESULT CprepDiskStopDefense( [in] CPREP_DISKID DiskId );
DiskId: The identifier of the ClusPrepDisk representing the disk.
Return Values: A signed 32-bit value that indicates return status. If the method returns a negative value, it has failed. Zero or positive values indicate success, with the lower 16 bits in positive nonzero values containing warnings or flags defined in the method implementation. For more information about Win32 error codes and HRESULT values, see [MS-ERREF] sections 2.2 and 2.1.
