If you change the management address or discovery address in an HA environment through DHCP or tmsh, the BIG-IQ might stop functioning when you restart.
BIG-IQ won't be able to function because it cannot reach its stored data.
This can happen when you use DHCP without a static IPAM lease or if you change the IP address via tmsh.
Now if the IP address is altered in a standalone configuration, the datastore configuration will be corrected. In an HA configuration, this will still lead to a non-functioning system. It is highly recommend that users use a static IP or an infinite lease through DHCP/IPAM
