You can run a Report from the Task bar on the left side of the Navisphere UI.   Just follow the Wizard - select the report you want to run or run all reports to get an idea of what information is available - select the "Available Storage Report" for unused Raid Group capacity.  Or you can click on Tasks/Reporting/Generate Report from the top of the UI. These reports are only available from the Navisphere UI.  A step wise process : To determine the total capacity of the array. 1.select the reporting tab  2.run the generate report  3.then select the array  4.under system profile  5.select the physical disk details  6. A report will be generated containing the raw capacity and usable capacity   
I have a Clariion CX4-240.  I am logged into Navisphere 6 and i need to figure out how much total storage i have compared to how much free space.  I am new to Navisphere so any help in the right direction would be great.  Thanks.
