A system group is a group of systems used solely for authorizations. System groups can be managed directly from the command line interface (CLI) using the mxngroup command, or they can be managed indirectly through the GUI.
Managing System Groups from the GUIA system group is created when an authorization is created using a system collection. This system group is named after the collection with three digits appended, usually 001. For example, All Racks 001. The system group contains the systems that were displayed during system selection, and is saved when the authorization is created. The contents of the system group is updated with the current contents of the collection when:
Another authorization is created using the collection
An authorization using the system group is updated
Using mxngroup from the CLI
In the first two cases, the current contents of the collection are displayed for verification. When deleting authorizations, a system group that is no longer used in any authorization is deleted.
Managing System Groups from the CLI Using Mxngroup
System groups can be created directly using the mxngroup command. When system groups are created in this manner, a top-level collection is created and named after the system collection with three digits appended, usually 001. The collection contains the systems in the system group only when the system group is first added, later modifications will not be reflected in the collection.
The contents of the system group can be updated with the current contents of the collection by using the -u parameter for mxngroup:
mxngroup –m –g <groupname> -u
When deleting authorizations, a system group that is no longer used in any authorizations is deleted.
