+Change the state of the external LED associated with
+.Ar disk .
+.Ar disk
+Should be either the device name of the disk, like
+.Cm da12 ,
+or
+.Cm all .
+to indicate all disks attached to SES controllers.
+.El
+.Sh EXAMPLES
+Turn off all external LEDs:
+.Pp
+.Dl Nm Cm locate all off
+.Pp
+Turn on the external LED of drive
+.Pa da15 :
+.Pp
+.Dl Nm Cm locate da15 on
+.Sh SEE ALSO
+.Xr ses 4
+.Sh HISTORY
+The
+.Nm
+utility first appeared in
+.Fx 11.0 .
+.Sh AUTHORS
