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