NOTE: All images and log entries in this article are from a Veritas support lab.
Worker node appliances are in red color under the Appliances tab with Role Unavailable. Below is an example (See Figure 1).

In the master server log file, the following log message will be present:

On the worker nodes, there's a warning message like the following in the server log:
2024-08-24 09:54:27,670 WARN [admin.jmx.Connection] (clusterupdateservice.clusterupdateservice:[]) [#71000] Admin Services Error : Unable to connect to eDP-App1.eDP.lab:2595 after 30 of 60 attempts - Will retry in 8 secs
When adding an appliance to the distributed architecture (DA) cluster, a popup message shows (See Figure 2):
Verify Connection Failed
No response received.
-Check your Host Address.
-Check your Clearwell Application Port.
-Check that this appliance is on-line.

During the eDiscovery Platform (eDP) installation/upgrade process, the installer will ask to manage the firewall. If the person who is installing the software answers no, then the installer will not add/modify the inbound allowed rules on the node. If during an upgrade, and the person who is installing answers no, then the firewall inbound rules will not be modified to the new java path location. Therefore, the worker nodes cannot communicate back to the master server. The firewall should have all expected inbound rules or should be disabled to prevent unexpected product behavior.
