History
Kenneth D. Merry 36d0fa44e2 Add the ability to rescan or reset devices specified by peripheral 
name and unit number in camcontrol(8).

Previously camcontrol(8) only supported rescanning or resetting
devices specified by bus:target:lun.  This is because for
rescanning at least, you don't have a peripheral name and unit
number (e.g. da4) for devices that don't exist yet.

That is still the case after this change, but in other cases, when
the device does exist in the CAM EDT (Existing Device Table), we
do a careful lookup of the bus/target/lun if the user supplies a
peripheral name and unit number to find the bus:target:lun and then
issue the requested reset or rescan.

The lookup is done without actually opening the device in question,
since a rescan is often done to make a device go away after it has
been pulled.  (This is especially true for busses/controllers, like
parallel SCSI controllers, that don't automatically detect changes
in topology.)  Opening a device that is no longer there to
determine the bus/target/lun might result in error recovery actions
when the user really just wanted to make the device go away.

sbin/camcontrol/camcontrol.c:
	In dorescan_or_reset(), if the use hasn't specified a
	numeric argument, assume he has specified a device.  Lookup
	the pass(4) instance for that device using the transport
	layer CAMGETPASSTHRU ioctl.  If that is successful, we can
	use the returned bus:target:lun to rescan or reset the
	device.

	Under the hood, resetting a device using XPT_RESET_DEV is
	actually sent via the pass(4) device anyway.  But this
	provides a way for the user to specify devices in a more
	convenient way, and can work on device rescans when the
	device is going away, assuming it still exists in the EDT.

sbin/camcontrol/camcontrol.8:
	Update the man page for the rescan and reset subcommands
	to reflect that you can now use a device name and unit
	number with them.
