Protocols — SCSI Bus Support
Version 1.10 12/01/02 13-11
Description
The EFI_SCSI_PASS_THRU_PROTOCOL.GetNextDevice() function retrieves the Target
ID and LUN of a SCSI device present on a SCSI channel. If Target is 0xFFFFFFFF, then the
Target ID and LUN of the first SCSI device is returned in Target and Lun and EFI_SUCCESS
is returned. If Target and Lun is a Target ID and LUN value that was returned on a previous call
to GetNextDevice(), then the Target ID and LUN of the next SCSI device on the SCSI
channel is returned in Target and Lun, and EFI_SUCCESS is returned. If Target is not
0xFFFFFFFF, and Target and Lun were not returned on a previous call to
GetNextDevice(), then EFI_INVALID_PARAMETER is returned. If Target and Lun
are the Target ID and LUN of the last SCSI device on the SCSI channel, then EFI_NOT_FOUND
is returned.
