Setting up Mirroring in a Unified Environment
The search appliance supports mirroring for a node participating in a unification configuration. For
example, suppose your unification configuration contains a primary node A and a secondary node C.
You want to add node B as a mirror of node A and node D as a mirror of node C. To accomplish this:
•
On node A, add node B as a replica
•
On node B, add node A as a primary
•
On node C, add node D as a replica
•
On node D, add node C as a primary
There is no automatic failover, so if a node goes down, you have to adjust the topology manually. For
example, if node A goes down, you would have to direct the serve traffic to node B while also adding
node C as the unification secondary of node B. Similarly, if node C goes down, you would have to add
node D as unification secondary of node A.
