Task 4: Prevent Future Problems
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
