Issue/Introduction

An administrator observes this error while trying to add site pair "Unable to retrieve pairs from extension server at https://xxxx:8043.  A runtime error occurred in the vSphere Replication Management Server. Exception details: 'EntityManagerFactory is closed'."

Environment

Live Site Recovery 9.x

Cause

The error “EntityManagerFactory is closed” occurred because the HBR service took over 30 minutes to start listening on port 8123. During this delay, the HMS service could not connect and shut down, which closed the EntityManagerFactory.

hms.log:

Resolution

Once the HBR service successfully started listening on port 8123, HMS was able to connect, and the “EntityManagerFactory is closed” error no longer appeared in the logs.
