Severity: 2-Critical


After upgrading BIG-IP software and reconfiguring high availability (HA), gossip may show 'UNPAIRED' and the REST endpoint /resolver/device-groups/tm-shared-all-big-ips/devices/ may show only one device.


The gossip output shows 'UNPAIRED', and the REST endpoint reports only one decide. SSL Orchestrator does not work as expected


-- This has been observed during upgrade from 14.x.x to 15.x.x. -- Reconfigure HA. -- View gossip results and REST endpoint output.


If gossip shows 'UNPAIRED' after upgrade, you may need to do following at both devices: 1. Delete existing device information: restcurl -X DELETE shared/resolver/device-groups/tm-shared-all-big-ips/devices 2. Force update: bigstart restart restjavad restcurl -X POST -d '{}' tm/shared/bigip-failover-state
