site power problems due to electrical storm

Greg reports LSB is without power after an electrical storm passed through the region this evening. LDAS is subsequently down for the evening.

The CDS status is:

DAQ is still running. h1fw0 has no disk system (it is located in the LSB) but h1fw1 continues to write frames to the MSR RAID. I have turned off monit on h1fw0 to stop it constantly going through  a start/crash/restart cycle. The MEDM screens could not resolve h1dc0's epics channels. I verified that daqd was running on h1dc0 (has been since 21st of this month) and that CA clients on the H!FE LAN can see this IOC. So it appears to be an EPICS gateway issue. I restarted the h1fe-cds epics gateway on h1cdsegw0 and this cleared the problem. Now only h1fw0 is blank on the DAQ medm screens, as expected.

I verified that h1fw1 is writing full, second and minute trend files.

All the front ends seem to have riden out the storm (pun intended) except for h1seib2 (seismic BSC). It reports having been rebooted at 18:19 local time, and is apparently missing timing at its IO Chassis so no models are running (ADC and DAC cards are visible, so IO Chassis is powered up). With no IOP model running, I assume the DAC outputs are stable at zero volts and it is safe to leave this in this state overnight.

All vacuum controls systems are operational, and their medm snapshots are being updated on the CDS web page.
