Description of problem:

Customer would like a command/script to manually remove a disk, and include in official documentation a manual procedure to set individual disk to zero-weight and pull. It is understood there is a way to do this already, what is desired is simple UX via a single command.

Too much understanding needed on part of user to pull a disk out of the cluster. this should be "something a person paid $7 an hour can do", without knowing what's happening underneath says $CUSTOMER.
