8.8. Storage and Permissions

8.8.1. Managing System Permissions for a Storage Domain

As the SuperUser, the system administrator manages all aspects of the Administration Portal. More specific administrative roles can be assigned to other users. These restricted administrator roles are useful for granting a user administrative privileges that limit them to a specific resource. For example, a DataCenterAdmin role has administrator privileges only for the assigned data center with the exception of the storage for that data center, and a ClusterAdmin has administrator privileges only for the assigned cluster.
A storage administrator is a system administration role for a specific storage domain only. This is useful in data centers with multiple storage domains, where each storage domain requires a system administrator. Use the Configure button in the header bar to assign a storage administrator for all storage domains in the environment.
The storage domain administrator role permits the following actions:
  • Edit the configuration of the storage domain.
  • Move the storage domain into maintenance mode.
  • Remove the storage domain.

Note

You can only assign roles and permissions to existing users.
You can also change the system administrator of a storage domain by removing the existing system administrator and adding the new system administrator.
