  title: Microsoft Azure Event Hubs Configure Geo-Disaster Recovery Pairing
  summary: Create a Geo-DR alias pairing a primary namespace to a secondary, then poll the configuration until replication provisioning succeeds.
  description: >-
    Establishes Geo-disaster recovery for an Event Hubs namespace. The flow
    creates a Disaster Recovery alias on the primary namespace pointing at a
    secondary partner namespace, then polls the configuration until its
    provisioning state reaches Succeeded so replication is confirmed active. Each
    step inlines its ARM {properties:{...}} request and provisioning-state polling
    so the pairing can be executed and monitored directly.
