Set up BIG-IQ in a Manual High Availability Configuration
How do I configure BIG-IQ systems in a high availability
configuration?
Setting up BIG-IQ in a high availability configuration ensures that you
always have access to the BIG-IP devices you are managing. In a BIG-IQ high availability
configuration, the BIG-IQ system replicates configuration changes since the last
synchronization from the primary device to the secondary device every 30 seconds. If it
ever becomes necessary, you can have the secondary peer take over management of the BIG-IP
devices.
You can also set up BIG-IQ in an auto failover configuration. For
more information, refer to

Availability Auto Failover Configuration

.Add a standby BIG-IQ for a high availability configuration
Before you can set
up BIG-IQ in a high availability (HA) configuration, you must have two licensed BIG-IQ
systems and you must have added the primary and secondary SSL certificate to the primary
BIG-IQ system. It's a good idea to have the BIG-IQ systems in a high availability
configuration to be on different platforms for additional insurance that both BIG-IQ
systems won't fail.
Configuring BIG-IQ in a high availability (HA) pair means that you can still manage your
BIG-IP devices even if one BIG-IQ systems fails.
Best practice
is to install the active and standby BIG-IQ systems on separate hardware platforms. With
this practice, if a hardware issue takes the active BIG-IQ offline, it can failover to
the standby BIG-IQ and you can continue managing your BIG-IP devices.
- At the top of the screen, clickSystem.
- On the left, clickBIG-IQ HA.
- Click theAdd Secondarybutton.
- Type the properties for the BIG-IQ system that you are adding.
- Click theAddbutton at the bottom of the screen.
The BIG-IQ system synchronize. Once they are
finished, both appear as ready (green).
Change a BIG-IQ system in a high availability pair to a standalone
system
If the one of your BIG-IQ systems in an HA pair is having any type of system
issue, you might want to make it a standalone system until you can fix the problem
or until you are finished setting up BIG-IQ again.
- At the top of the screen, clickSystem.
- On the left, clickBIG-IQ HA.
- Click theBIG-IQ HA Settingsbutton and then click theReset to Standalonebutton.
This
BIG-IQ system becomes a standalone system from which you can start managing your
devices.
Remove the standby BIG-IQ system from the HA pair
If the F5 BIG-IQ Centralized Management system is
configured in an HA pair, you must remove the standby BIG-IQ system before you upgrade
the active BIG-IQ.
- At the top of the screen, clickSystem.
- On the left, clickBIG-IQ HA.
- ClickRemove Standby.A dialog box opens, prompting you to confirm that you want to remove the standby BIG-IQ from this group.
- ClickRemoveto confirm that you want to take the standby BIG-IQ from the group.The system logs you out of the BIG-IQ while it removes the standby BIG-IQ.
- Log back in to the active BIG-IQ.For a while, both the active and the standby BIG-IQ continue to display. After a few minutes, the screen updates to display a single standalone BIG-IQ.
