A cluster is a grouping of ArcGIS Server machines participating in an ArcGIS Server site. You can use ArcGIS Server Manager to edit and configure the machines participating in your clusters.
To edit a cluster in Manager, follow these steps:
- Open Manager and log in. If you need help with this step, see Logging in to Manager.
- Click Site > GIS Server > Clusters.
- In the Clusters module, locate the cluster you want to configure and click Edit .
- Add or remove ArcGIS Server machines from the cluster using the controls in the Edit Cluster Machines window.
If an ArcGIS Server machine you want to add to the cluster does not appear in the list, make sure it has been added to your site and is not currently participating in another cluster. For more information, see About adding an ArcGIS Server machine to a site.
If the cluster is currently hosting services and you remove all machines from the cluster, a warning displays indicating that the services will be stopped after applying your changes. If you require the services in the cluster to remain running, you'll need to add another machine to the cluster or edit the services to use another cluster before proceeding. For instructions on how to change the cluster hosting a service, see Editing service properties in Manager.
- Click Apply.
The edits to your cluster are applied and appear in the Clusters module.
