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 a NonStop S-Series Server
Many operations and troubleshooting tasks are performed using the TACL command
interpreter or one of the OSM or TSM 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.
You use the OSM or TSM applications to perform such functions as starting the
NonStop S-series server, identifying system components, and monitoring the status of
system components and resources.
OSM is required to manage NonStop S-series systems with IOAM enclosures and
related components and Fibre Channel disk drive enclosures.
OSM is the required system management tool for servers that use 6780 switches in
ServerNet clusters, but OSM also provides system management for earlier versions of
ServerNet clusters.
For more details on the functions of the TACL command interpreter and the OSM and
TSM applications, see Appendix B, Tools and Utilities for Operations.
This subsection provides basic information about accessing the TACL command
interpreter and the OSM and TSM applications.
