6.7. Hosts and Permissions

6.7.1. Managing System Permissions for a Host

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 host administrator is a system administration role for a specific host only. This is useful in clusters with multiple hosts, where each host requires a system administrator. You can use the Configure button in the header bar to assign a host administrator for all hosts in the environment.
The host administrator role permits the following actions:
  • Edit the configuration of the host.
  • Set up the logical networks.
  • Remove the host.
You can also change the system administrator of a host by removing the existing system administrator and adding the new system administrator.
