Hello Bjorg.

Actually, it depends on your HA configuration.

REF - https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/bigip-device-service-clustering-administration-12-1-1/6.html

​

The correct answer would be, when the device is realesed from offline then it stars to share communicacion with its pair trying to figure out which will be the active.

​

This means that with common ha configuration, the device will rise as standby, but if you have configured HA order with this device in first position, then it will be active.

​

Active-Active is only possible if you lose HA communication between pairs or you are facing a bug.

​

Let me know if this clarifies your initial question.

KR,

Dario.
