Computer Restart Procedures

Here is where we should keep information on how to restart the computers that periodically need restarting.

• c1ioo

This machine runs the c1x03, c1ioo, and c1gpt FE models.

On reboot, these models should automatically start up.

c1ioo is a Sun X4600 machine. As such for a complete shutdown (not normally necessary but sometimes), do the following:

Shutdown the computer normally. (Power button or "shutdown -h now").

Go out to the rack and unplug all 4 power supply cables on the back of the machine.

Wait for a bit for the machine to completely stop (30 seconds or so).

Plug all the cables back in, and press the power button.

. DAQ issues To ensure that dataviewer can receive data is you need running on the fb machine:

/opt/rtcds/caltech/c1/target/fb/daqd -c ./daqdrc &

/opt/rtcds/caltech/c1/target/fb/nds pipe > nds.log &

To start by hand, "ssh fb", "screen", then type the above two commands, then press ctrl-a and then ctrl-d.

For testpoints to be available for a given front end, you need running on the correct front end computer:

The IOP needs to be running, since it handles, it is genamed something like c1x00, c1x01, etc.

"sudo /opt/rtcds/caltech/c1/scripts/startc1SYSNAME" where SYSNAME is something like sus or ioo or x02

The above starts the IOCs, awgtpman, and loads the front end module.

mx_streams running (use "sudo /etc/restart_streams") this should start a mx_stream for each front end system and is needed to talk to the fb

To check if the front ends are loaded, you can use "lsmod" on the front end machine, looking for c1SYSNAMEfe entries To check if the IOCs are running, you can "ps -ef | grep epicsC1.cmd" To check if mx_streams are running, you can "ps -ef | grep mx_stream" To check if awgtpman are running, you can "ps -ef | grep awgtpman"
