Severity: 2-Critical


Configuring high availability (HA) fails in Amazon Web Services (AWS) across Availability Zones (AZs). The system posts aws-parse-network-description error messages in /var/log/ltm similar to the following: -- notice logger: /usr/libexec/aws/aws-failover-tgactive.sh (traffic-group-1): Started. ... -- debug aws_advanced_failover: command: /usr/libexec/aws/aws-parse-network-description -i i-76e03061 -p -f /tmp/tmppvI76L ended with status 2 had stdout: Unable to locate subnet for IP and stderr: -- err aws_advanced_failover: Failed command: "/usr/libexec/aws/aws-parse-network-description -i i-76e03061 -p -f /tmp/tmppvI76L" Check to make sure secondary address exists on target ENI -- debug aws_advanced_failover: ENI is Unable to locate subnet for IP -- err aws_advanced_failover: Could not transfer EIP ...


The HA configuration across AZs fails.


This occurs when the following conditions are met: -- Configuring HA in AWS across AZs. -- Using BIG-IP Virtual Edition (VE). -- Using a version of the AWS Advanced HA failover iApp earlier than f5.aws_advanced_ha.v1.4.0rc2.tmpl.
