sa(7) — SPECIAL FILES AND DEVICES
NAME
SA − devices administered by System Administration
DESCRIPTION
The files in the directories /dev/SA (for block devices) and the /dev/rSA (for raw devices) are used by System Administration to access the devices on which it operates. For devices that support more than one slice (like disks) the /dev/(r)SA entry is linked to the slice that spans the entire device. Not all /dev/(r)SA entries are used by all System Administration commands.
