Affected Product(s):
BIG-IQ ADC
Known Affected Versions:
5.4.0, 5.4.0 HF1, 5.4.0 HF2
Opened: Dec 12, 2017 Severity: 3-Major
Under specific conditions, when you deploy a change to a BIG-IP HA cluster running version 11.6, that deletes both an eviction policy reference and its associated eviction policy.
This causes a failed deployment and disconnects the BIG-IP cluster.
This issue occurs only on an 11.6.x HA cluster when the eviction policy reference is part of a virtual server or is the general eviction policy reference. This doesn't happen occur when the eviction policy reference is part of a route domain. The issue also does not on occur on BIG-IP 12.x (latest hotfix) HA clusters and above.
Perform a two-step deployment. First, delete the reference to the eviction policy and create a deployment with "Keep Unused Objects" selected. When you deploy these changes, BIG-IQ removes only the eviction policy reference. Next, create a second deployment. This time, select "Remove Unused Objects". When you deploy these changes, BIG-IQ removes the eviction policy. If your HA cluster is in a disconnected state as a result of a one-step deployment with "Remove Unused Objects" selected, you can restore the HA cluster by performing a manual sync on the BIG-IP. The BIG-IP might be offline for a minute or so before the BIG-IP cluster is restored.
