Opened: Jun 05, 2020 Severity: 3-Major
If you try to add a secondary BIG-IQ to a primary BIG-IQ to create a high availability (HA) configuration and the TCP port 5432 between the BIG-IQ systems are not open, the high availability (HA) configuration attempt fails.
The high availability (HA) configuration attempt fails and the first BIG-IQ system deletes the /var/lib/pgsql/data folder.
Adding a secondary BIG-IQ to a primary BIG-IQ without the TCP port 5432 open between them. Secondary Postgres cannot be restarted.
To fix this issue, open the TCP port 5432 between the BIG-IQ systems and if configured in an auto failover configuration, the BIG-IQ DCD Quorum as well.
