- You must assign the RBAC user to the host, plug-in, credential, resource groups, and storage system (for clones) that you want to delete.

Prerequisites to remove a host with clones created from clone lifecycle operation
- You must have created clone jobs using clone lifecycle management for SQL databases.
- You must have created an RBAC role with clone read and delete, resource read and delete, resource group read and delete, storage read and delete, provision read and delete, mount, unmount, plug-in installation and uninstallation, host read and delete permissions.
