Reestablishing a BIG-IQ auto failover HA configuration after
- Log into the command line of the BIG-IQ that failed and type the following command:ha_reset -f <discovery IP>.

- In theIP Addressfield, type the discovery address you want to set up as the standby BIG-IQ.This is the same IP address the peers in a high availability configuration use to communicate.IPv6 short form addresses are not supported.
- Type the local administrativeUsernameandPasswordfor the system.
- Type theRoot Passwordfor the system.
- For theFailover setting, selectAuto Failover.For auto failover to work, you must have the following ports open on the active and standby BIG-IQ as well as the quorum DCD.
- TCP port 2224
- UDP port 5404
- UDP port 5405
- Click theSet Up Quorum Devicebutton, select the quorum DCD from the list, and type itsRoot Password.
- If you want BIG-IQ to use a floating IP address when automatically failing over to the standby BIG-IQ, select theEnable Floating IPEnablecheck box and type the address.The floating IP address must be on the same network (this configuration uses Gratuitous ARP packets) as the active and standby BIG-IQ systems’ local management address (interface eth0) and not any of the discovery self IP addresses. This does not restrict HA traffic; HA traffic can be on any of the available interfaces. Floating IP addresses are not supported if your active and standby BIG-IQ systems are in a public cloud environment, such as AWS, Azure, or VMware.If you choose not to use a floating IP address and the active BIG-IQ fails over, you'll have to provide all users access to the newly active BIG-IQ by providing the IP address.
