/**

Sends a SCSI Request Packet to a SCSI device that is attached to the SCSI channel. This function
|
|
supports both blocking I/O and nonblocking I/O. The blocking I/O functionality is required, and the
|
|
nonblocking I/O functionality is optional.
|
|
|
|
@param This A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance.
|
|
@param Target The Target is an array of size TARGET_MAX_BYTES and it represents
|
|
the id of the SCSI device to send the SCSI Request Packet. Each
|
|
transport driver may choose to utilize a subset of this size to suit the needs
|
|
of transport target representation. For example, a Fibre Channel driver
|
|
may use only 8 bytes (WWN) to represent an FC target.
|
|
@param Lun The LUN of the SCSI device to send the SCSI Request Packet.
|
|
@param Packet A pointer to the SCSI Request Packet to send to the SCSI device
|
|
specified by Target and Lun.
|
|
@param Event If nonblocking I/O is not supported then Event is ignored, and blocking
|
|
I/O is performed. If Event is NULL, then blocking I/O is performed. If
|
|
Event is not NULL and non blocking I/O is supported, then
|
|
nonblocking I/O is performed, and Event will be signaled when the
|
|
SCSI Request Packet completes.
|
|
|
|
@retval EFI_SUCCESS The SCSI Request Packet was sent by the host. For bi-directional
|
|
commands, InTransferLength bytes were transferred from
|
|
InDataBuffer. For write and bi-directional commands,
|
|
OutTransferLength bytes were transferred by
|
|
OutDataBuffer.
|
|
@retval EFI_BAD_BUFFER_SIZE The SCSI Request Packet was not executed. The number of bytes that
|
|
could be transferred is returned in InTransferLength. For write
|
|
and bi-directional commands, OutTransferLength bytes were
|
|
transferred by OutDataBuffer.
|
|
@retval EFI_NOT_READY The SCSI Request Packet could not be sent because there are too many
|
|
SCSI Request Packets already queued. The caller may retry again later.
|
|
@retval EFI_DEVICE_ERROR A device error occurred while attempting to send the SCSI Request
|
|
Packet.
|
|
@retval EFI_INVALID_PARAMETER Target, Lun, or the contents of ScsiRequestPacket are invalid.
|
|
@retval EFI_UNSUPPORTED The command described by the SCSI Request Packet is not supported
|
|
by the host adapter. This includes the case of Bi-directional SCSI
|
|
commands not supported by the implementation. The SCSI Request
|
|
Packet was not sent, so no additional status information is available.
|
|
@retval EFI_TIMEOUT A timeout occurred while waiting for the SCSI Request Packet to execute.
