Affected Product:  See more info
BIG-IQ Platform(all modules)

Opened: Jul 26, 2019
Severity: 4-Minor

Symptoms

If you select "Use Management Address for HA Peer Communication" when configuring BIG-IQ in an auto-failover high availability configuration, BIG-IQ returns an error: 400 Bad Request.

Impact

"Use Management Address for HA Peer Communication" fails to use the management address and returns an error.

Conditions

This happens when configuring auto-failover HA since that configuration needs a DCD configured as the Quorum device. This can also happen during Manual failover when a DCD is discovered on the BIG IQ.

Workaround

1. You must use the setup wizard (https://<ip>/ui/setup) when setting up the HA communication for a BIG-IQ in an auto-failover high availability. 2. The DCD discovery address is used for communication between each BIG-IQ and the Quorum DCD and must be on the same network as the HA communication. 3. If you're using a floating IP address, you must set the management network, regardless of the HA communication network (that can be on either management or a self IP address). 4. Before changing the default self IP address, you must first delete/un-manage all devices that you have established communication with: <DCD's IP address>.
