Use the clustered system diagnostic and service-aid commands to diagnose and find system problems.
The system enables you to perform service activity, such as problem determination and repair activities, with a limited set of command-line tools. When you are logged in under the administrator role, all command-line activities are permitted. When you are logged in under the service role, only those commands that are required for service are enabled. The system diagnostic and service-aid commands apply under the service role.
