You can initiate a failover manually with the request command. A manual failover bumps up the priority of the redundancy group for that member to 255.

For background information, read: |
After a manual failover, the new primary continues in that role until there is a failback. If there is a failback, the manual failover is lost and state election is made based on priority and preempt settings. A failback in manual failover mode can occur if the primary node fails or if the threshold of a redundancy group 0 reaches 0.
 |
Caution: Be cautious and judicious in your use of redundancy group 0 manual failovers. A redundancy group 0 failover implies a Routing Engine (RE) failover, in which case all processes running on the primary node are killed and then spawned on the new primary RE. This failover could result in loss of state, such as routing state, and degrade performance by introducing system churn. |
