Task 4: Prevent Future Problems

Solving problems that occur with your system can be exciting because it is active and stimulating. Preventing problems is often less dramatic. But in the end, prevention is more productive than solving problems. The more work you do to prevent problems before they arise, the fewer problems that will arise at potentially critical times.

These questions provide a framework for your problem-prevention efforts:

•Why did this problem occur? What was the root cause? Were there any contributing causes?

•

•

•

•

•

How serious was the problem?

What is the likelihood that it will occur again?

Is it possible to eliminate the causes of this problem?

Is it possible to reduce the likelihood that this problem will occur in the future?

Can automation tools be used to detect and respond to preliminary symptoms of this problem?

•Can anything be done now to minimize the damage that would result from a reoccurrence of this problem?

•Can the problem resolution process be improved in any way?

Logging On to an Integrity NonStop Server

Many operations and troubleshooting tasks are performed by logging on to your Integrity NonStop server from a system console and using the TACL command interpreter or one of the OSM applications. For example, the TACL command interpreter allows you to access SCF, which you use to configure, control, and collect information about objects within subsystems. For examples of OSM tasks and functions, see Overview of OSM Applications on page 1-11.

System Consoles

A system console is a personal computer approved by HP to run maintenance and diagnostic software for Integrity NonStop servers. New system consoles are preconfigured with the required HP and third-party software. When upgrading to the latest RVU, software upgrades can be installed from the HP NonStop System Console Installer CD.

System consoles communicate with Integrity NonStop servers over a dedicated service LAN (local area network). System consoles configured as the primary and backup dial- out points are referred to as the primary and backup system consoles, respectively.

The OSM Low-Level Link and OSM Notification Director applications reside on the system console, along with other required HP and third-party software. OSM Service Connection and OSM Event Viewer software resides on your server, and connectivity
