Hi Jim, Two controllers are required to avoid single point of failure in high availability.
That check is there from the beginning, before SC absence allowed and SC roaming features. I guess, your system is running with SC absence allowed feature. When a cluster goes headless, you are actually losing high availability, and SC absence allowed feature is there only to prevent the cluster reboot, and to successfully recover the cluster when controller(s) comes back.

We have a pre-existing design that has 1 System Controller, and several Payload nodes. When we try to implement this for OpenSAF usage, it gets flagged as a validation error. The script is making the following validation check: * If (System_Controller_count < 2) and (Payload_Count > 0) * Generate validation error * Endif Can anyone explain why this check is here? Is this to meet some requirement imposed by the AMF Specifications? As a workaround, we have removed this validation check from the script, to allow the file to be generated. Does anyone see an issue with removing this check, and just allowing OpenSAF to run a single controller with multiple payloads? Thanks.
