HBA_SendReadCapacity routine
The HBA_SendReadCapacity routine sends a SCSI read capacity command to the indicated remote port.
Syntax
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
);
Parameters
handle [in]
Contains a value returned by the routine HBA_OpenAdapter that identifies the HBA through which the SCSI read capacity command is sent.portWWN [in]
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.fcLUN [in]
Indicates the fibre channel logical unit number of the logical unit to which the SCSI read capacity command will be sent.pRspBuffer [out]
Pointer to a buffer that receives the output data of the SCSI read capacity command.RspBufferSize [in]
Indicates the size, in bytes, of the buffer at pRspBuffer.pSenseBuffer [out]
Pointer to a buffer that receives the SCSI sense data.SenseBufferSize [in]
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.
Return value
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.
| Return code | Description |
|---|---|
| HBA_STATUS_OK | Returned if the complete payload of a reply to the SCSI read capacity command was successfully retrieved. |
| HBA_STATUS_ERROR_ILLEGAL_WWN | Returned if the HBA referenced by handle does not contain a port with a name that matches HbaPortWWN. |
| HBA_STATUS_ERROR_NOT_A_TARGET | Returned if the specified remote port specified by portWWN does not have SCSI target functionality. |
| HBA_STATUS_ERROR_TARGET_BUSY | Returned if the SCSI read capacity command could not be delivered without causing a SCSI overlapped command condition. |
| HBA_STATUS_SCSI_CHECK_CONDITION | Returned if a SCSI check condition occurred and SCSI send data is provided in the buffer at pSenseBuffer. |
| HBA_STATUS_ERROR | Returned if an unspecified error occurred that prevented the execution of the SCSI inquiry command. |
