Status Codes Returned
EFI_SUCCESS The SCSI Request Packet was sent by the host, and
TransferLength bytes were transferred to/from
DataBuffer. See HostAdapterStatus,
TargetStatus, SenseDataLength, and SenseData
in that order for additional status information.
EFI_BAD_BUFFER_SIZE The SCSI Request Packet was not executed. The number of bytes
that could be transferred is returned in
TransferLength. See
HostAdapterStatus, TargetStatus,
SenseDataLength, and SenseData in that order for
additional status information.
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.

Packet. See
HostAdapterStatus, TargetStatus,
SenseDataLength, and SenseData in that order for
additional status information.

invalid. The SCSI Request Packet was not sent, so no additional
status information is available.
EFI_UNSUPPORTED The command described by the SCSI Request Packet is not
supported by the host adapter. The SCSI Request Packet was not
sent, so no additional status information is available.
