Using the DRS Tab
The DRS tab is available when you select a DRS cluster object from the inventory panel in the vSphere Client.
This tab displays information about the DRS recommendations made for the cluster, faults that have occurred in applying such recommendations, and the history of DRS actions. You can access three pages from this tab. These pages are named Recommendations, Faults, and History.
