  title: WebSphere Cluster Controlled Restart
  summary: Find a cluster, stop all its members, and start them again.
  description: >-
    A WebSphere Network Deployment cluster operation. The workflow lists the
    clusters in the cell to confirm the target exists, reads the cluster to
    capture its members and current status, stops all members of the cluster, and
    then starts them again so configuration or maintenance changes take effect
    across the whole cluster. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
