I have 1 Policy Server that is in a hung state in a Load Balanced Architecture. Can I remove the network cable of that hung Policy Server to disconnect it from the network, and thus, to disable it from Load Balanced Architecture?
Removing the hung Policy Server by simply unpluging the cable will remove that Policy Server from Round Robin.
But, you must consider that it will take a little time for each WebAgent to consider the policy server as unreachable and to mark it as "unusable" in the round robin list. So you might expect a slow down on services delivered by each webagent. The safer way to do it will be to remove this Policy Server from HCO and SmHost.conf file on each webagent, but this will require webagent to be restarted.
