Restart PV Gateway:

The information here may be used when a problem is detected with a PV gateway. Typically this will be when an access to a PV served by a PV gateway is not responding (use caget PV to check). In most cases, the solution will be to restart the PV gateway.

Identify which PV gateway has an issue, based on the table above. Use of one of the following two methods to restart the PV gateway.

Take gwEbeamServe (the gateway serving Ebeam PVs to Photon side) for example:

 

To verify if a PV gateway is working properly, refer to the table above for Host (gateway_host) and CAS port (CAS_port), and define EPICS_CA_ADDR_LIST

Be sure to do this test, using one of the hosts in the facility served by the gaeway. For example, to verify gwLCLS4FACET

 

Troubleshoot PV gateway:

Take Photon PV gateway gwEbeamServe for example. The procedure to troubleshoot this gateway is documented in http://www.slac.stanford.edu/grp/cd/soft/unix/slaconly/ElectronPhotonGateway.html
