Routine Description:
|
|
Sends a SCSI Request Packet to a SCSI device that is attached to
|
|
the SCSI channel. This function supports both blocking I/O and
|
|
non-blocking I/O. The blocking I/O functionality is required,
|
|
and the non-blocking I/O functionality is optional.
|
|
|
|
Arguments:
|
|
This - Protocol instance pointer.
|
|
Target - The Target ID of the SCSI device to
|
|
send the SCSI Request Packet.
|
|
Lun - The LUN of the SCSI device to send the
|
|
SCSI Request Packet.
|
|
Packet - A pointer to the SCSI Request Packet to send
|
|
to the SCSI device specified by Target and Lun.
|
|
Event - If non-blocking 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 non-blocking I/O is performed,
|
|
and Event will be signaled when the SCSI Request
|
|
Packet completes
|
|
|
|
Returns:
|
|
EFI_SUCCESSThe - 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 executed, but the
|
|
entire DataBuffer could not be transferred.
|
|
The actual number of bytes 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.
|
|
EFI_DEVICE_ERROR - A device error occurred while attempting to send
|
|
the SCSI Request Packet. See HostAdapterStatus,
|
|
TargetStatus, SenseDataLength, and SenseData in
|
|
that order for additional status information.
|
|
EFI_INVALID_PARAMETER - Target, Lun, or the contents of ScsiRequestPacket
|
|
are 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.
|
|
EFI_TIMEOUT - A timeout occurred while waiting for the SCSI
|
|
Request Packet to execute. See HostAdapterStatus,
|
|
TargetStatus, SenseDataLength, and SenseData in
|
|
that order for additional status information.

Routine Description:
|

Used to retrieve the list of legal Target IDs for SCSI devices

on a SCSI channel.
|
|
|
|
Arguments:
|
|
This - Protocol instance pointer.
|
|
Target - On input, a pointer to the Target ID of a
|
|
SCSI device present on the SCSI channel.
|
|
On output, a pointer to the Target ID of

|
the next SCSI device present on a SCSI channel.

|
An input value of 0xFFFFFFFF retrieves the

|
Target ID of the first SCSI device present on

|
a SCSI channel.
|

|
|
present on the SCSI channel.On output, a pointer
|
|
to the LUN of the next SCSI device present on a
|
|
SCSI channel.
|
|
Returns:
|
|
EFI_SUCCESS - The Target ID of the next SCSI device on the SCSI
|
|
channel was returned in Target and Lun.
|
|
EFI_NOT_FOUND - There are no more SCSI devices on this SCSI channel.
|
|
EFI_INVALID_PARAMETER - Target is not 0xFFFFFFFF, and Target and Lun were
|
|
not returned on a previous call to GetNextDevice().
