CDS power outage recovery, summary

Richard, Filiburto, Patrick, Cyrus, Jim, Dave

VME crates for vacuum controls were restarted, medm screens were operational in the control room immediately after power was restored.

All front ends a back online. A few started with high IRIG-B timing numbers which gradually drifted good. The longest recovery was h1seih16 which took several hours.

All front ends are now running RCG2.8.5 with the exception of h1psl0, please see my separate alog.

Only one front end is not running correctly, h1susauxex has a very large IRIG error which is not fixable by a hard power cycle of the FE-CPU and the IO Chassis. We also performed a power cycle of the timing fanout and IRIG-B fanout at EX. We will continue the investigation of h1susauxex tomorrow, all other EX systems are running OK.

The DAQ is back up and running after the rack reconfiguration.

After the power was returned, we took the opportunity to clone the boot disk of h1boot and perform an fsck and upgrade of cdsfs0.

web snapshots of medm screens were started for offsite monitoring of vacuum vent.

tomorrow we will start the secondary systems and test stands.
