After this feature has been enabled, you can continue with the configuration. **Procedure ** 1. Log in to the System Manager. 2. Go to **Maintenance > HA Configuration** to open the **HA Configuration** window. 3. Modify one or more of the fields, as necessary. Refer to [HA Configuration window](docId:6GK-9Sf3X6KLeS6KLVtCb) table for details. 4. Click **Save **> **Apply **> **OK.** ## HA Configuration window The following table summarizes fields and descriptions in the **HA Configuration **window: Table: HA Configuration window Fields | Fields | Description | | -------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | High Availability | This feature provides the ability to **Enable** or **Disable** HA. The default is **Disable**. The **Enable** radio button needs to be selected followed by **Save and Apply** in order to enable HA. Enabling and Disabling HA starts (enable) or stops the scheduling process. | | Mode | This feature indicate the initial role this server will have in the HA configuration. The two options are:
- **Primary **– This is the Ivanti EPMM where all traffic and work will go to during normal operation.
- **Secondary** – This is the redundant Ivanti EPMM server, which frequently checks the status of the Primary (heartbeat) and periodically replicates from it. The replication process is initiated and controlled by the Secondary server. This ensures the Secondary is up-to-date and ready to take over in case of a Primary failure. | | Manage Trusted Hosts | This feature allows for the setup and configuration of the SSH keys between Ivanti EPMM servers. The exchange of SSH keys is used to establish the trust relationship between servers by using public-key cryptography and challenge-response authentication. This step is fundamental for HA Ivanti EPMMs to communicate with each other. | | HA Status
(Primary mode only) | This section provides details on the last recorded HA activity and only displays when **Primary** is selected for Mode. It provides the status of its pair system, its hostname/IP address, and the last time the **Secondary** has synchronized with it. | | Node Status
(Secondary mode only) | This option only displays when **Secondary** is selected for **Mode**.
This feature indicates the current server status in relationship to the Ivanti EPMM HA configuration. The default value of **Standby** indicates the server is a Standby server and is allowed to sync with its Primary server. The state of **Active** indicates the system was originally set up as **Standby**, but has been promoted to **Active**. This occurs when the Secondary server is not able to communicate with the Primary server and a failover event occurs OR when the **Active** button is manually selected. In either case, a Standby server in **Active** state does not sync with its Primary server. Only a Standby/passive server syncs with its Primary server. |
