Add a backup
- Right-click the High Availability icon.
- Select Add High Availability Backup.
The high availability feature involves the
use of a second Load Balancer machine. The first Load Balancer machine performs load balancing for
all client traffic as it would in a single Load Balancer configuration. The second Load Balancer
machine monitors the health of the first and takes over the task of load balancing if it
detects that the first Load Balancer machine failed.
Note: Do not add a backup Load Balancer machine that is running Load Balancer for
IPv4 and IPv6. Ensure that both Load Balancer machines are running the same version.
- In the dialog box, type the port number for the heartbeat messages.
- Select a role:
- Primary: sends connection data to the backup machine on an ongoing basis.
- Backup: machine is in a standby state, continually updated and ready to take over.
- Both: Each machine is the primary load balancer for a subnet of the clusters, and
the partner machine will assume the active role for all clusters if the other machine fails.
- Select an Auto or Manual recovery strategy.
- Enter an address on this machine that will be used to communicate with the
partner. This is the non-forwarding address (NFA), unless you are adding multiple heartbeats.
- Enter an address on the partner machine to communicate with
this machine. This is the NFA address of the partner, unless you are adding multiple
heartbeats.
- Click OK.
