I replaced the borrowed server with the permanent one today. Before Removing the current server, Before, I performed several additional preparations:
- Updated Chiara hostables to IP 192.168.113.48 for c1auxex
apt-get install procserv
- copied ETMXaux2.* files in /cvs/cds/caltech/target/c1auxex2 to ETMXaux.* and changed references from /opt/rtcds/epics (which was a local directory on c1auxex2) to /cvs/cds/rtapps/epics-3.14.12.2_long in the copied files
- Added instruction
Environment="LD_LIBRARY_PATH=/cvs/cds/rtapps/epics-3.14.12.2_long/base/lib/linux-x86_64:/cvs/cds/rtapps/epics-3.14.12.2_long/modules/modbus/lib/linux-x86_64/:/cvs/cds/rtapps/epics-3.14.12.2_long/modules/asyn/lib/linux-x86_64"
to /etc/systemd/system/modbusIOC.service (required for burtwb dependencies)
Then I replaced the server:
- IFO was in LSC mode with both arms locked
- Backed up ETMX alignment using save feature in IFOalign screen
- Disengaged LSC mode
- Shut down ETMX watchdog
- Disconnected ETMX satellite box
- Shut down c1auxex2 and c1auxex
- Performed the server swap
- Booted c1auxex
- Made sure EPICS channels were back online and channel defaults were restored
- Reconnected satellite box
- Turned on watchdog
- Turned on OpLevs
- Engaged LSC mode -> both arms were instantly locked
I returned c1auxex2 to Larry, who needed it back asap because of some hardware failure
