[Hallb-engineering] DC R2 pressure and Helium Buffer dewar problems

[bruhwel at jlab.org]

It seems that the torus and the buffer dewar ioc's had network difficulty
this weekend.  I hope its fixed, but I do not know.  As far as the restore
on the buffer dewar ioc, I can ask Sue about that and see what she says. 
We should ask Sue to change these settings in the database so that they
come back on boot I'd think.

What values do we want on boot?

Regards,
Krister
