Set the active Management Server

If the currently active Management Server is unreachable, set a different Management Server to active. If is also recommended to set a different Management Server active before you change the platform of the Management Server that is currently active.

Note: Changing the active Management Server is primarily meant for disaster recovery. We do not recommend changing the active Management Server unless it is necessary.

CAUTION:

If the currently active Management Server is unreachable when you change the active Management Server, but might possibly recover, disconnect the active Management Server from the network. Disconnecting the currently active Management Server prevents having two active Management Servers online at the same time.

When a Management Server is the active Management Server, it has full control of all administrative Domains. Setting a Management Server to standby releases full control of all administrative Domains. Another Management Server can take full control of all administrative Domains and become the new active Management Server.

The engines continue to operate normally even when no Management Server is reachable, so there is no interruption to any network services.

Set the previous active Management Server to standby, then manually synchronize the databases to return to normal operation.

SMC HA Administration dialog box

Use this dialog box to control how the Management Servers function in an HA environment and how the database is replicated between the active Management Server and the standby Management Servers. You can also use it to see the status of Log Servers, and run diagnostics about the communication status between all SMC servers.

Note: If the replication status of a standby Management Servers shows that there are issues with the database replication, make sure that you are connected to the active Management Server to see the current status of all the components in the SMC.
