So after doing a lot of research. It came out that the latest dsm client has bug and crashes everytime I tried to use the discover utility. So I used this version mentioned in this post  [URL] and I was able to successfully discover both controller and finish setting them up. Everything looks good.  I really appreciate your help.      
Hello There we have aquired a Dell SCV3020 using our company buy back program. The Customer who we bought from told us that they did a factory reset using the dsm client. I am trying to configure the compellent and i am unable to do so. i have a dhcp network, the IDRAC for each controller get an ip np problem. i can access the idrac of both controllers. but i dont get any ip for controllers. i tried the unisphere discovery but no luck. tried to connect the laptop directly to the controller still did not pick up anything. i dont know what wouuld be the next step here. i can access the centos 7 prompt. but the default password works. any idea would be appreciated. and is there a way i can do a hardware factory reset? Thanks in advance
