You can modify a SnapCenter role to add or remove users or groups, change the permissions associated with the role, or rename it. It is especially useful to modify roles when you want to change or eliminate the permissions used by an entire role.
If you are using the SnapCenter Plug-in for VMware vSphere to protect VMs, VMDKs, or datastores, you must use the VMware vCenter GUI to modify a SCV role. For information, see the vCenter documentation.
