we are using IPCC 7.1.4,CVP 3.1, ccm 4.2.3, we had the CCMPG and the VRUPG and the CTIOS,CTI server located on the same machine.
we had two redundant sides A&B they were located at the same data center, recently we had moved side B to another location to activate the DR function of the system, after moving side B and started it up the system goes down and the PG gives error that the private network with the duplex partener is failed and the CVP gives error that time out waiting for icm instruction.
note: the same errors appear in side A PG if we switch to side B PG, so the two sides PGs will work fine if we aoperate one at a time
now we are operating the sides except side B PG.
note: we had the same heartbeats connection when the two sides were located at the same location, except for the cross over cable we had changed to strieght cable to be connected to the switch instead of directly between the servers, also we had 50 MB bandwidth between the two sides.
