77 *! \brief  tiINIIOStart
78 *
79 *   Purpose:  This routine is called to initiate a new SCSI request.
80 *
81 *  \param   tiRoot:           Pointer to initiator driver/port instance.
82 *  \param   tiIORequest:      Pointer to the I/O request context for this I/O.
83 *  \param   tiDeviceHandle:   Pointer to device handle for this I/O.
84 *  \param   tiScsiRequest:    Pointer to the SCSI-3 I/O request and SGL list.
85 *  \param   tiRequestBody:    Pointer to the OS Specific module allocated storage
86 *                             to be used by the TD layer for executing this I/O.
87 *  \param   interruptContext: The interrupt context within which this function
88 *                       is called.
89 *  \return:
90 *
91 *  tiSuccess:     I/O request successfully initiated.
92 *  tiBusy:        No resources available, try again later.
93 *  tiIONoDevice:  Invalid device handle.
94 *  tiError:       Other errors that prevent the I/O request to be started.
