You can manually rediscover a cluster from the Cluster Setup page in order to obtain the latest information about the health, monitoring status, and performance status of the cluster.
You can manually rediscover a cluster when you want to update the cluster—such as by increasing the size of an aggregate when there is insufficient space—and you want Unified Manager to discover the changes that you make.
When Unified Manager is paired with OnCommand Workflow Automation (WFA), the pairing triggers the reacquisition of the data cached by WFA.
In the left navigation pane, click Storage Management > Cluster Setup.
On the Cluster Setup page, click Rediscover.
Unified Manager rediscovers the selected cluster and displays the latest health and performance status.
