Recovering a Failed Secondary HA Host
You can recover a failed secondary high-availability (HA) JSA host if the build version of the secondary HA host must be the same as the JSA build version installed on the primary HA host.
Ensure that the following requirements are met:
The required hardware is installed.
You need the cluster virtual IP address and the secondary HA host IP address. You can identify the IP address in the System and License Management window. For more information, see Viewing HA Cluster IP Addresses.
A keyboard and monitor are connected by using the VGA connection.
- Type root at the login prompt to start the installation wizard.
- Accept the End User License Agreement.
- Select the appliance type: High Availability Appliance.
- In the Type of Setup window, select HA Recovery Setup.

- Configure the JSA network settings.
In the Cluster Virtual IP Address Setup window, enter the cluster virtual IP address.
In the Network Information Setup window, enter the IP address of the secondary HA host.
