If you type “cainfo <pv name>”, one of the fields it returns is “host”, which is often the server that the PV’s IOC is running on.

 

But sometimes the “host” is really a gateway server and not the IOC server itself. For example:

 

[...] 

And then to find the real IOC server I would do “ssh cagw01.cs.nsls2.local” and then do “cainfo XF:03ID-CT{RG:C2}T-I” again, and I get:

 

[...] 

And now I have xf03idc-ioc2-313.nsls2.bnl.local, which is the real IOC server. Is there a way to find this IOC server without ssh?


Using Channel Access? No.
Many installations (including NSLS 2 btw.) are using the ChannelFinder directory service to collect and provide that kind of information.
