Are you referring to a field in the SAS transport header or perhaps to the obsolete LUN field in the SCSI CDB? Additionally, as far as I know every SCSI command should be executed by exactly one SCSI LUN. I'm not aware of any support in the SCSI specs for broadcasting a single SCSI command to multiple LUNs. Thanks, Bart.
