MDM Trouble Report for 2008 Sep 26

Telescope: 1.3m
Observer(s): Atlee (OSU)
Instrument: 4k Camera

Problem(s) Encountered:
McGraw began to be unresponsive when I asked it to list the
detailed information about a file that had been written to 
/lhome/data/.  A subsequent request for data taking in Prospero
indicated that Caliban had become unresponsive.  (Error message
lost.)  When attempting to disable the data-taking programs and
re-start, the system froze completely.  It stopped responding to
ping requests from Hill, and I was forced to do a hard restart
of the system using the reset button on the machine in the
computer room.

Upon reboot, running the Prospero startup script yielded:
  ***ERROR: The Caliban and IC disks are not synched
  Image storage will not work until this is done
  Make sure Caliban is up and running (restart
  Caliban or type >IC PING in Caliban window
  and try again

Neither of the suggested courses of action yielded desired
result, and error message recurred.  Performed lightning
shutdown to restart system from known state.  This corrected
the problem

Also, please note that a number of files that should have been
recorded as part of the focus test (14 files total) were not
transferred from the IC to /lhome/data/.  This suggests that
the initial problem occurred during the recording process and
not later.

Upon coming back from the shutdown (which took the TCS) the
telescope refused to slew in RA.  Had to kill the TCS GUI
and restart, which brought up its complaint about HA not homed.
The TCS control apparently does not deal well with sending the
focus home.

Also, during one of the focus study sequences, the RA control
motor began jerking rather than tracking smoothly.  At the same
time the control over Dec from the hand paddle failed
completely.  During this sequence, the telescope appeared
to slowly drift to the north, i.e. the guide star drifted to
the south during the sequence.  This problem was ultimately
resolved by slewing the telescope back to the zenith.
