	We have a TU81+ tape drive hooked up to our DECsystem 5400 running
Ultrix 4.0.  I often disconnect the tape drive to connect it to our VAX.

	Several seconds after disconnecting it, the DS5400 console responds
with something like "msi0: resynching controller."  When I later reconnect
the tape drive, the DS5400 does not recognize it.  When I reboot the DS5400,
everything is fine.

	I want a way to tell the DS5400 that the tape drive is reconnected,
WITHOUT rebooting.  Is there a method?

	(Before anyone asks:  yes, I know all about "rdump" and other tools
for using a tape drive on a remote machine.  For the work I am doing, I 
*need* the TU81+ directly connected to both machines.  Ever try to boot a
VAX into standalone mode from a remote drive?)
