MDM Trouble Report for 2001 Jan 2

Telescope: 2.4m
Observer(s): C Gerardy (Dartmouth)
Instrument: TIFKAM

Problem(s) Encountered:
	Here's a description of our troubles with the TIFKAM 
computers this afternoon.  The system is back up now and seems
to be running fine.

	As we already noted in our observing log, we had a brief
power outage this weekend.  All of the 2.4m control systems 
were unaffected, except for the 2 TIFKAM computers (WC & IC).  
These were apparently just plugged into a normal wall outlet, 
and were not on the UPS system.  Paul called as we were finishing
our run last night, and I informed him of this.. (actually he
already knew).  Anyway he was going to move the computers over to
UPS power today, so before going to bed, I shut them down.  

	When I got up, Paul had moved the computers to UPS 
power, and had restarted them, but he hadn't set up anything
on the sparc stations.  So I tried to start caliban & prospero,
and prospero wasn't happy.   In particular the IE indicator was
red.  So I brought everything down and tried to reboot a couple
of times.  However, it wasn't coming back up.  

	Fortunately Paul was talking to Dr. Pogge at the time,
and with his help we eventually got the system back up.  The
solution apparently was to  power cycle  the electronics boxes
on the instrument, and then re-booting the IC.  This solved the
IE problem.  A subsequent disk synch problem between the WC and 
the IC was solved by restarting the WC.
