If you are starting LOIS with the Mimir instrument and hangs at a point during the start up. if the last 3 lines in the console log or right hand window in LOIS are
IRarray: IR Core Module Initialization Complete
Error Unable to identify the command: instrument_init
Loading MimirInst Instrument Configuration
Then this means that the daemon that runs the filter wheels, slit, decker, and camera has some how got into a bad state. Here are the steps to fix this.
1. Log into yggdrasil
saturn% ssh camera@yggdrasil |
2. Kill the Mimir Instrument Daemon
1% pkill -TERM MimirInst |
3. Make sure there are no MimirInst processes running
2% ps -ef | grep MimirInst |
4. Restart the MimirInst process
3%/usr/local/bin/MimirInst |
If for some reason you still see a process in step 2 use the command pkill -9 MimirInst. Another possible problem is that the socket will be bound and you will not be able to start the MimirInst daemon. In that case make sure that there is not a MimirInst daemon running and wait for a minute or two until the OS cleans up the bound sockets and try restarting the MimirInst again until it starts normally.
