Thanks for the response, Helmut. Because this system is pretty old the customer no longer has the "utility CD". Is there another document that contains this information?
You can search for Centera online help on support.emc.com to find the documentation for the version of the Centera.
for example for 4.2.2: https://support.emc.com/docu44447_Centera_4.2.2_Online_Help.htm?language=en_US
