HA Cluster behavior on AWS
Hello, I've managed to run two F5 in different "Availability Zone" (in same VPC)from scratch and they can sync configuration objects that i created. CFE configuration took some time to figured out but eventually its is working right now. I have a couple of questions about HA cluster on Aws. Can you help me to understand? - While testing this setup i saw that if active device goes offline for any reason, the peer device does nothing. Even, the CMI logs on stand-by unit says that the peer device unreachable. Is that normal? Should stand-by device take action to go active, after when it realized the peer is unreachable. - Devices can sync objects i added including pools, iRules, nodes, virtual servers and etc. Also, the status indicator on top left corner says devices are "In Sync". However, when i looked at "Device Manager > Devices", each device sees other device is offline. Why? - Despite there is a Sync-Failover device group configuration on both devices, each device says that they are "Active" itself. In setups with help of AWS Cloud Formation or Terraform guided, does this happen? - When i use GUI for failover, it takes around 1 minute and 20 seconds. But if i trigger failover with "curl" command it only takes 5 seconds. Is that normal?

BigIP HA Cluster upgrade to 12.1.2- loosing DeviceTrust
im trying to upgrade my BigIp HA (Active/passive) Cluster- Version 12.0.0 Build 2.0.644 to Version 12.1.2 Build 1.0.271 Forced my Standby-Device offline and booted from new Boot Location with the "install Configuration" option of my current Boot Lokation. The Device is comming up, configuration seems fine i see all of my VS and Pools. Config Sync is not possible because of different versions. im aware of that. But the Device Trust is gone! im not sure how im supposed to move on at this point. how do i get my traffic groups running on the patched Device without Device trust, is a failover even possible? can i ignore Device Trust and release the Device online/force the active offline? or am i supposed to fix Device trust first, which means breaking the trust and trying to build it up again, does that work with two different versions? This is a production environment, im affraid that the failover won't work. i want to upgrade without a Downtime of my trafficGroups Thank you for your help.
