Hi. I just wanted to take a minute to update the group on my progress and thank everyone for taking the time to respond. I received many great responses and I am very appreciative!! My NMR is back up and running great and I have learned quite a bit from this experience. If your interested, please see my summary below of how I was able to unlock the Sun without flipping the power switch and I also got my lock signal back along with spinner control.
First, the frozen Sun computer... I did not want to flip the switch and to shut it off unless I was certain that all other options were exhausted. Many people suggested that I try [Ctrl-d] or [Ctrl-c] or [Ctrl-q] or [Ctrl-z]. However, my keyboard was not responding at all. Another user suggested that I unplug the keyboard and then plug it back in. This would generate a hardware interrupt and give me an OK prompt. It worked and I was able to restart the computer from there. When the computer came back I ran the fsck -y to check from problems and everything was fine.
Unfortunately, when VNMR came back, I was still having the same lock/spinner problems. One person suggested that I check communication with the Ethernet by typing "ping gemcon" from a shell window. The response was "No answer from the Gemini" and it confirmed my initial suspicion that the Ethernet was the problem. I checked the Ethernet connections and reset the console, then "ping gemcon" again and the console responded this time. I checked the acqi window and everything was back to normal.
Thank you so much for all of your help!!

Subject: AMMRL: Solaris locked up
Hello All:
I am new to this community and fairly new to NMR management in general. I inherited a Varian Gemini 2300 which runs off an Sun Microsystems Ultra5 with Solaris. I had to install a new 1H transmitter board the other day, once I did that I was having trouble with the lock signal (very erratic but not drifting). It was suggested to me that this could just be a communication issue from the console to the computer and to check all connections in the console and reboot the Sun. I did that and while the system was starting back up I saw the message "No response from ethernet network--cable down." |looked this up in the manuals and found a troubleshooting section to check if the ethernet is working properly. I logged in as root, and entered the following commands:
varian# cat /etc/hostname.1e0
then it said "file not found" so I typed
varian# cd /etc
varian# vi hostname.1e0
varian# vi hosts
then the computer screen completly locked up. I cannot do anything except move my mouse around the screen (but I cannot click on anything)!! I am very new to the sun system and our IT refuse to touch the sun system. I know that these systems do not like to be started and stopped a lot but I dont know what to do... is there a way to safely restart or fix this?
Thanks!!
Briana
