To rediscover Oracle VM Servers:
Click the Servers and VMs tab.
Select the server pool in which the Oracle VM Servers reside in the navigation tree.
Select Servers from the Perspective drop-down list. Select one or more Oracle VM Servers in the management pane, and click Rediscover Server
in the perspective toolbar.
The configuration and storage information about the Oracle VM Servers is updated in Oracle VM Manager.
