I have an inherited X20 unit (dual controllers) with wiped boot drives.
I have installed TrueNAS 25.04 on both controllers’ boot volumes, primary controller boots up with accessible web interface that prompted to set a new truenas_admin password. System hardware information and chassis graphics shows that Truenas 25.04 is recognizing the x20 chassis properly. Upon setting static IP’s of the primary controller, I then booted up the second controller.
Secondary controller boots up with a responsive web UI but primary controller is not aware of it, nor any HA configuration options are available. Secondary controller is simply acting independantly and ready for me to set the truenas_admin password.
At this point, I am notified in the system notifications pane that I do not have an “HA License” applied to the system.
In hopes to try to resolve this one with TrueNAS support, I was told to refer to the community for support on this matter instead of being given any options at all to obtain an “HA License” to allow this hardware to work at its original potential.
Digging deep in the googles and geminis, I came across some vague information to install/run a high availability .deb package to enable high availability but have yet to try this.
I want to imagine that there’s ways to jump into the CLI to enable the HA management tools/menu. Can someone help me revive this hardware?
