Powervault Manager allows you to view the physical layout of the hard disks in a graphical layout as seen below. However, the RAID levels and hot spare assignments are not found on this main screen.
In the Dell Powervault Manager user interface, navigate to the Storage Setup page and you will find the list of pools created along with their associated sizes and RAID levels. You can also see the list of spares assigned in the system. Below is a sample screenshot of this page.
