Here's the correct answer: Any old Dell account will do. Ideally, create one dedicated to SCG so there's no chance of a password reset by the user of the account breaking SCG. The problem I've been having is on the back end. Support tech had to generate the key & PIN for me.
Setting up SCG. When I sign in, I get this message: "This page is only accessible to DellEMC business users." I've used the account I use with Dell, and I've used the account of the purchasing agent who purchased the server (via DCN). Both accounts receive the same message. I've contacted our current DCN rep; he's looking into it and does not have an answer yet. What constitutes a "DellEMC business user"?
"DellEMC business users" qualifications
