Removing clusters


You can remove a cluster from Unified Manager by using the Configuration/Cluster Data Sources page. For example, you can remove a cluster if cluster discovery fails, or when you want to decommission a storage system.

Before you begin

You must have the OnCommand Administrator role or the Storage Administrator role.

About this task

This task removes the selected cluster from Unified Manager. After a cluster is removed, it is no longer monitored. The instance of Unified Manager registered with the removed cluster is also unregistered from the cluster.

Removing a cluster also deletes all its storage objects, historical data, storage services, and all associated events from Unified Manager. These changes are reflected on the inventory pages and the details pages after the next data collection cycle.

  2. On the Configuration/Cluster Data Sources page, select the cluster that you want to remove and click Remove.
