[Dsg-halla_gem] GEM gas and ECAL IOC

[Marc Mcmullen]

Additionally,

I have seen this at least once in the past, where the IOC crashed and we had trouble reconnecting. But it had something to do with the accelerator gateway.

Until that got straightened out, nothing worked.

There is something odd, because I just tried manually changing a value using a caput and that worked. I have tried restarting the GEM gas monitoring software, the program starts, runs for maybe 30 seconds and then slows to a crawl, then eventually times out.

Just as a check, I restarted the program on the ECAL cRIO to see if that would fix that issue but it did not.

So, I think there may still be issues with the IOC since it crashed.

Hi William,

I have two different system that seem to be unable to reach the PVs running on the IOC.

Attached is the error coming from one of the SBS GEM Rpis.

Hi Marc,

Are the variables back?  The computer that hosts those PVs crashed last night.  The ioc should have automatically restarted.  I haven’t had a chance to check for myself yet today.

Hi Bill and Ellen,

It looks like the IOC which hosts the PVs for the GEMs and ECAL heater controls needs to be rebooted. Is it possible for that to be done remotely?


Regards,
Marc
