How to recover from sol13116 interfaces unpopulated

Per the solution article, forcing the unit back online should resolve the issue. If that isn't what you're seeing, then you're not experiencing SOL13116.

When you say cluster, are you referring to an HA pair with another viprion ? The word 'cluster' refers to a grouping of blades within a Viprion chassis, where one is primary, and the rest slave to it. A HA pair (or HA group) consists of two or more BigIP devices that operate in Active/Standby mode.

In other words, if you disable the cluster, then you're only affecting the ability of the blades in the chassis to work together as one. If you reset device trust, you're affecting the ability to perform a failover of a traffic-group from one BigIP to another.

Make sure that the cluster is up and running, and that all the blades show green under system / cluster (or 'tmsh show sys cluster' on the command line)
