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.
