3.1.4.1.6 ApiGetQuorumResource (Opnum 5)

(Protocol Version 2) The ApiGetQuorumResource method returns information about how quorum is configured in the cluster.

The server MUST return:

  • The name of the storage class resource that is determining quorum for the cluster.

  • The fully qualified disk path associated with the quorum resource that contains the cluster configuration data file area.

  • The maximum size to which the quorum log file can grow. The server usage details of quorum log file is implementation-specific.

The server SHOULD accept an ApiGetQuorumResource request if its protocol server state is read-only and MUST accept the request for processing if it is in the read/write state, as specified in section 3.1.1.

 error_status_t ApiGetQuorumResource(
   [out, string] LPWSTR* lpszResourceName,
   [out, string] LPWSTR* lpszDeviceName,
   [out] DWORD* pdwMaxQuorumLogSize
 );

lpszResourceName: The address of a pointer where the server MUST, upon successful completion of this method, write the address of a Unicode string buffer containing the name of the quorum resource. The server MUST allocate as much memory as is required to return the name. If the method fails, this parameter MUST be ignored.

lpszDeviceName: The address of a pointer where the server MUST, upon successful completion of this method, write the address of a Unicode string buffer containing a path on the disk represented by the resource identified in the lpszResourceName parameter. The server MUST allocate as much memory as is required to return the path. If the method fails, this parameter MUST be ignored.

pdwMaxQuorumLogSize: The address of a 32-bit integer where the server MUST, upon successful completion of this method, write the maximum size, in bytes, to which the quorum log file can grow.

Return Values: The method MUST return the following error codes for the conditions that are specified as follows.
