Parameters
Mode A pointer to the EFI_SCSI_PASS_THRU_MODE data for this
SCSI channel. Type EFI_SCSI_PASS_THRU_MODE is
defined in “Related Definitions” below.
PassThru Sends a SCSI Request Packet to a SCSI device that is connected
to the SCSI channel. See the
PassThru() function
description.
GetNextDevice Used to retrieve the list of legal Target IDs and LUNs for the
SCSI devices on a SCSI channel. See the
GetNextDevice()
function description.
BuildDevicePath Used to allocate and build a device path node for a SCSI device
on a SCSI channel. See the
BuildDevicePath() function
description.
GetTargetLun Used to translate a device path node to a Target ID and LUN.
See the
GetTargetLun() function description.
ResetChannel Resets the SCSI channel. This operation resets all the SCSI
devices connected to the SCSI channel. See the
ResetChannel() function description.
ResetTarget Resets a SCSI device that is connected to the SCSI channel. See
the
ResetTarget() function description.
The following data values in the EFI_SCSI_PASS_THRU_MODE interface are read-only.
ControllerName A Null-terminated Unicode string that represents the printable
name of the SCSI controller.
ChannelName A Null-terminated Unicode string that represents the printable
name of the SCSI channel.
AdapterId The Target ID of the host adapter on the SCSI channel.
Attributes Additional information on the attributes of the SCSI channel.
See “Related Definitions” below for the list of possible
attributes.
