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 GUI

A 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.

Any further changes to the system collection do not affect the system group or authorizations, unless updated by one of the following options.

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.

Additional changes to the system group or the collection do not affect the other, unless updated by one of the following options or by using the GUI as described above. Therefore, changes to the collection do not affect authorizations, and changes to the system group do not affect the collection view unless specifically updated.

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

This does not display the systems in the collection. To display the updated contents of the system group, use mxngroup –lm –g <groupname>.

Setting up a periodic task to dynamically update a system group is not recommended. A collection based on system attribute scan be compromised, adversely affecting authorizations in HP Systems Insight Manager (HP SIM), if those attributes are based on a non-secure protocol such as SNMP, or are maintained by a user with no configuration rights. Additionally the collection itself can be modified by a user with no configuration rights, again adversely affecting authorizations.

When deleting authorizations, a system group that is no longer used in any authorizations is deleted.
