The HBA_SendReadCapacity routine sends a SCSI read capacity command to the indicated remote port.
HBA_STATUS HBA_API HBA_SendReadCapacity( _In_ HBA_HANDLE handle, _In_ HBA_WWN portWWN, _In_ HBA_UINT64 fcLUN, _Out_ void *pRspBuffer, _In_ HBA_UINT32 RspBufferSize, _Out_ void *pSenseBuffer, _In_ HBA_UINT32 SenseBufferSize );
Contains a value returned by the routine HBA_OpenAdapter that identifies the HBA through which the SCSI read capacity command is sent.
Contains a 64-bit worldwide name (WWN) that uniquely identifies the remote target port to which the SCSI read capacity command is sent. For a discussion of worldwide names, see the T11 committee's Fibre Channel HBA API specification.
Indicates the fibre channel logical unit number of the logical unit to which the SCSI read capacity command will be sent.
Pointer to a buffer that receives the output data of the SCSI read capacity command.
Indicates the size, in bytes, of the buffer at pRspBuffer.
Pointer to a buffer that receives the SCSI sense data.
On input, indicates on input the size, in bytes, of the buffer at pSenseBuffer. On output, this member indicates the number of bytes of sense data returned.
The HBA_ScsiReadCapacity routine returns a value of type HBA_STATUS that indicates the status of the HBA. In particular, HBA_ScsiReadCapacity returns one of the following values.
Returned if the complete payload of a reply to the SCSI read capacity command was successfully retrieved.
Returned if the HBA referenced by handle does not contain a port with a name that matches HbaPortWWN.
Returned if the specified remote port specified by portWWN does not have SCSI target functionality.
Returned if the SCSI read capacity command could not be delivered without causing a SCSI overlapped command condition.
Returned if a SCSI check condition occurred and SCSI send data is provided in the buffer at pSenseBuffer.
Returned if an unspecified error occurred that prevented the execution of the SCSI inquiry command.
