Failover relationships will initially appear as Empty and must be activated by adding a scope to the relationship from the IPAM page. You can either create a new scope or select an existing one. If the failover relationship was previously empty, it will be created on the Microsoft DHCP server.

Microsoft DHCP scopes participating in failover relationships are grouped and labeled as such in the Authority column on the IPAM page. The Failover relationship column displays the name of the failover relationship to which the scope belongs.

Adding scopes to failover relationships

There are three ways to add scopes to a failover relationship, either in the Web Application or through the API.

To add scopes to the relationship:

  1. On the IPAM page, locate and select the scope in the data grid.
  2. Use either the Action or Row … menu to select Add scope to failover.
  3. In the dropdown, select a failover relationship to add the scope to.

  4. Select Confirm.

  • Use the API command AdsdDHCPScopesFromDHCPFailoverRelationship, which adds scopes to failover relationships. Specify a reference to the DHCP scope and the failover relationship name.

If the failover relationship was empty before the scope was added to it, the status will change from Empty to Normal.
