Terms Used to Describe System Hardware Components

The terms used to describe system hardware components vary. These terms include:

•

•

Device

System resource or object

Device

A device can be a physical device or a logical device. A physical device is a physical component of a computer system that is used to communicate with the outside world or to acquire or store data. A logical device is a process used to conduct input or output with a physical device.

System Resource or Object

The term “system resource” is used in OSM documentation to refer to server components that OSM software displays, monitors, and often controls. The term “object” is often used when referring to a specific resource, such as “the Disk object.” All system resources are displayed in hierarchical form in the tree pane of the OSM Service Connection; many are also displayed in Physical or Inventory views of the view pane. The effect of selecting an object in either pane is the same: for example, you can view attributes for the selected system resource in the Attributes tab, view alarms for that resource (if any exist) in the Alarms tab, or right-click on the resource object and select Actions, to display the Actions dialog box (from which you can select and perform actions on the selected system resource). Besides physical hardware components, such as IOAM enclosures, power supplies, ServerNet adapters, and disk and tape drives, system resources also include logical entities that OSM supports, such as logical processors, ServerNet fabrics, and LIFs (logical interfaces).

Recording Your System Configuration

As a system operator, you need to understand how your system is configured so you can confirm that the hardware and system software are operating normally. If problems do occur, knowing your configuration allows you to pinpoint problems more easily. If your system configuration is corrupted, documentation about your configuration is essential for recovery. You should be familiar with the system organization, system configuration, and naming conventions.

Several methods are available for researching and recording your system configuration:

•

•

Maintaining records in hard-copy format

Using the OSM Service Connection to inventory your system

In the OSM Service Connection tree pane, select the System object. From the View pane drop-down menu, select Inventory to display a list of the system’s hardware resources. Click Save to save this list to a Microsoft Excel file.
