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 nonblocking I/O. The blocking I/O functionality is required, and the
|
||
|
|
nonblocking I/O functionality is optional.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
This - A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance.
|
||
|
|
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 chose 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.
|
||
|
|
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 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.
|
||
|
|
|
||
|
|
Returns:
|
||
|
|
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.
|
||
|
|
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.
|
||
|
|
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.
|
||
|
|
EFI_INVALID_PARAMETER- Target, Lun, or the contents of ScsiRequestPacket are invalid.
|
||
|
|
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.
|
||
|
|
EFI_TIMEOUT - A timeout occurred while waiting for the SCSI Request Packet to execute.

Routine Description:

can either be the list SCSI devices that are actually present on the SCSI channel, or the list of legal

On output, a pointer to the Target ID (an array of

|
||
|
|
channel. An input value of 0xF(all bytes in the array are 0xF) in the

Target array retrieves the Target ID of the first SCSI device present on

a SCSI channel.

on a SCSI channel.

|

This - A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance.

|
allocated and built. Transport drivers may chose to utilize a subset of

Lun - The LUN of the SCSI device for which a device path node is to be

|
||
|
|
|
||
|
|
DevicePath - A pointer to a single device path node that describes the SCSI device

allocating the buffer DevicePath with the boot service
