The scsi(8) manpage says:
The -p option can be used against the "super scsi" device /dev/scsi/super
to probe all devices with a given SCSI lun on a given SCSI bus. The bus
can be selected with the -b option and the default is 0. The lun can be
selected with the -l option and the default is 0. See scsi(4) for a de-
scription of the "super scsi" device.
The -r option can be used in FreeBSD 1.1 to reprobe a specific SCSI de-
vice at a given Bus, Target and Lun. This is not needed in FreeBSD 2.1,
since opening a fixed SCSI device has the side effect of reprobing it,
and probing with the bus with the -p option should bring on line any new-
ly found devices. See scsi(4) for a description of fixed scsi devices.
Does any of this actually work? Opening a device that wasn't on when the
system booted results in "device not configured messages".
The super scsi device doesn't exist and isn't reference in the scsi(4)
manpage.
