The NSX message bus is set up after host preparation once ESX Agent Manager (EAM) has notified NSX that NSX VIBs have been successfully installed on an ESXi host. This event indicates that the message bus setup on the host failed. Starting with NSX 6.2.3, a red error icon is shown next to the affected host on the Installation and Upgrade > Host Preparation tab.

Action: For troubleshooting steps, refer to NSX Troubleshooting Guide.

390002 High Yes Host messaging connection reconfiguration failed.

In certain situations where NSX finds the RMQ broker details have changed, NSX tries to send the latest RMQ broker information to the host. If NSX fails to send the information, this alarm is raised.

Action: For troubleshooting steps, refer to NSX Troubleshooting Guide.

390003 High Yes Host messaging configuration failed and notifications were skipped.
