Several adapters support SCSI_RESET to reset a specific target; you can get at it through "scsi_reset_target(sc_link)". You can start a unit with "scsi_start_unit(sc_link, flags)". In all cases you will then have to hope the system goes into the retry forever logic based on the "device in the process of coming ready".
