Thank you very much.  Where do I run this command from ?  Thanks !
I asked this question last week, but need to dive a little deeper.  I asked about zeroing out the data on the disks of a VNXe3300. I was pointed to a document containing commands to destroy the data and prepare the VNXe for decommission.  However, I need to get down to the byte level on the disks and overwrite the data on the disks themselves.   Is there an EMC tool that will do this?  Thanks !
