Tony, Dave:
The EDC is consistently not connecting to 17 of the 27 channels served by the CP1 overfill IOC. This started soon after the upgraded zotvac0 was installed. We ran the original IOC to see if the new machine was the issue, but the EDC still only connected to 10 of the 27 channels in H1EPICS_CP1.ini. It is the same block of 10 which connect, there is no obvious reason why these 10 (checked position in file, type of PV). So we are running the new zotvac0 overnight.
OPS: we expect the EDC disconnect channel count to remain at 17 or hopefully eventually drop to zero.
Looks like zotvac0 has gone offline and the EDC is now disconnected from all 27 channels. We'll leave it like this overnight and work on it first thing tomorrow.
