Opened: Dec 30, 2014
Severity: 3-Major


Logging information on BIG-IP VE for Failover on AWS was inadequate and did not provide the reason for failures in Failover.


The lack of logging messages that could pin-point the mis-configuration or connectivity issues on AWS makes it difficult to determine what is causing the Failover to fail.


Traffic-group failover sometimes failed without providing specific reason for the failure.



Fix Information

Added more logging details for AWS failover failure to assist in detecting problems in failover.

Behavior Change

Previously, the following AWS permissions were required when running failover: ec2:AssignPrivateIpAddresses and ec2:DescribeNetworkInterfaces. Failover could fail because of region or key issues, and so an additional AWS permission, ec2:DescribeInstanceStatus, is now also required for running failover.
