Bring back primary and standby nodes after both nodes fail by using the command line

In this scenario, the primary node has failed and the standby node has taken over as the new primary node. Before a new backup can be brought up, the new primary node fails. You need to bring back both nodes. System administrators can use the imaserver HighAvailability commands on the command line.

You can configure appliances for high availability by using the command line or by using the Amlen WebUI. For more information about using the Amlen WebUI to configure appliances for high availability, see Bring back primary and standby nodes after both nodes fail by using the GUI. In this scenario, the content of the store and configuration of Appliance B is preserved.

Ensure that the high availability parameters on Appliance B are correct by using the imaserver show HighAvailability command. You can update settings by using the imaserver update HighAvailability command.
Stop the Eclipse Amlen server for Appliance B by using the following command:
```
imaserver stop
```
Restart Appliance B and Appliance A by using the following command:
```
imaserver start
```

You can view high availability configuration details of the Eclipse Amlen appliance by using the imaserver show HighAvailability command. You can view information about the high availability role of the Eclipse Amlen appliance by using the imaserver status command.
