High Availability setup for Managing Nodes

Testing HA on 11.6 in my lab and trying to setup the config between two managers.  Based on the documentation I'm reading there doesn't appear to be a way to do this via the Web unless I have a manager of managers to config them from.  Is this true?  Also, I have performed the setup manually and it shows "Waiting for synchronization status" on the web page but I see no activity on the sync port of 1970 using Wireshark.  The HA tasks are running on the Prognosis config for both servers and the Windows Firewall is disabled.  Do I need to update the secondary server's HA config as well?  I copied the setup from the Primary with no luck.  The Secondary server states the following via the web:

 

Warning! The Prognosis node is currently not active. Please add any systems on the active node

 

Any guidance would be appreciated.

Re: High Availability setup for Managing Nodes

Hi MattAnderson,

Your understanding is correct that a manager node is needed to setup HA on a given pair. We use this manager node for all HA paring.


The "waiting for Sync status" is to wait for HA state from the HA pair, and this should take a minute or so.
If Manual Configuration is attempted, these steps must be performed on both servers in the HA Pair

Hi Matt,

 

That's correct. It needs a manager of managers for HA between managing nodes. Here's a diagram.

Thank you.  I'll try it with a MOM and see how that works.
