1. A method of partitioning management of a plurality of storage resources in a computing storage environment across a plurality of users by a processor device, wherein the plurality of users includes an existing administrator and an existing non-administrator, the method comprising: assigning the existing non-administrator a default user resource scope that is more limited than a user resource scope assigned to the existing administrator; associating existing storage resources with a default resource group; creating resource group objects for each new resource group; setting attributes in the resource group objects to define policies for storage resources to be associated with a corresponding new resource group; reassigning the existing non-administrator from the default user resource scope to a new user resource scope; reassigning the existing storage resources from the default resource group to the new resource group; and applying the policies and access scopes allowing the existing non-administrator to create new storage resources within a scope of the corresponding new user resource scope.
