Hello.

I was wondering if there is a command that will let me make a erasure of disks in a SC4020? 

Creating volumes and deleting them doesn't do it, yes, there is a lot of deleted info on the disks, but there are still readable data (Thinking GDPR).

When i'm on the commandline and i write disk and hit enter to get subcommands that i can use for disk, it's not clear to me that there is a command that will let me erase disks / sanitize them.
