Managing System Tree Objects

The Server Administrator system tree displays all visible system objects based on the software and 
hardware groups that Server Administrator discovers on the managed system and on the user's access 
privileges. The system components are categorized by component type. When you expand the main 
object known as 

System

, the major categories of system components that may appear are 

Main System 

Chassis

Software

, and 

Storage

.

To expand a branch of the tree, click the plus sign (

) to the left of an object, or double-click the 

object. A minus sign (

) indicates an expanded entry that cannot be expanded further. 

See Figure 6-2 available Server Administrator home page system tree objects.
