usage is the specification for when automatic failover is used.

Valid values:

never
Automatic failover will not occur. Manual failover is still available.
always_primary
For agents configured as Primary agents only. This agent should always be Primary. If another Primary agent is active when this agent starts, that agent will become a Secondary agent. If this agent cannot be a Primary agent, it will shut down.
primary_secondary
For agents configured as Primary agents only. This agent will try to start as a Primary agent. If another Primary agent is already active, this agent will become a Secondary agent. It becomes first in the ranking to become Primary during failover.
secondary_primary[n]
For agents configured as Secondary agents only: This agent will start as a Secondary agent. When the Primary agent ends, this agent is eligible to become the Primary agent.
- An optional integer [n] controls the ranking of multiple Secondary agents during failover. A lower number means a higher priority in the failover ranking.
- When multiple agents have the same ranking, the agent that started earliest will be considered to have a higher ranking.
- Default for [n] is 1. The range is 1-32.

Default is never.
