Field Documentation

VOID* EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::Cdb

A pointer to buffer that contains the Command Data Block to send to the SCSI device.

UINT8 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::CdbLength

The length, in bytes, of the buffer Cdb. The standard values are 6, 10, 12, and 16, but other values are possible if a variable length CDB is used.

VOID* EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::DataBuffer

A pointer to the data buffer to transfer between the SCSI controller and the SCSI device. Must be aligned to the boundary specified in the IoAlign field of the EFI_SCSI_PASS_THRU_MODE structure.

UINT8 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::DataDirection

The direction of the data transfer. 0 for reads, 1 for writes. A value of 2 is Reserved for Bi-Directional SCSI commands.

UINT8 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::HostAdapterStatus

The status of the SCSI Host Controller that produces the SCSI bus where the SCSI device attached when the SCSI Request Packet was executed on the SCSI Controller.

VOID* EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::SenseData

A pointer to the sense data that was generated by the execution of the SCSI Request Packet.

UINT8 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::SenseDataLength

On input, the length in bytes of the SenseData buffer. On output, the number of bytes written to the SenseData buffer.

UINT8 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::TargetStatus

The status returned by the SCSI device when the SCSI Request Packet was executed.

UINT64 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::Timeout

The timeout, in 100 ns units, to use for the execution of this SCSI Request Packet. A Timeout value of 0 means that this function will wait indefinitely for the SCSI Request Packet to execute. If Timeout is greater than zero, then this function will return EFI_TIMEOUT if the time required to execute the SCSI Request Packet is greater than Timeout.

UINT32 EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET::TransferLength

On Input, the size, in bytes, of InDataBuffer. On output, the number of bytes transferred between the SCSI controller and the SCSI device.
