Usage: vault step-down [options]
Forces the Vault server at the given address to step down from active duty.
While the affected node will have a delay before attempting to acquire the
leader lock again, if no other Vault nodes acquire the lock beforehand, it
is possible for the same node to re-acquire the lock and become active
again.
Force Vault to step down as the leader:
$ vault step-down
For a full list of examples, please see the documentation.
