Maintaining a System
2-6 Fault Tolerant System Administration (R1004H) HP-UX version 11.00.03
Tracking and Fixing System Problems
An important function of a system administrator is to identify and fix problems
that occur in the hardware, software, or network while the system is in normal use.
Continuum systems are designed specifically for continuous availability, so you
should experience fewer system problems than with other systems running the
HP-UX operating system. Nevertheless, there are a variety of potential problems
in any system, such as the following:
■ Users cannot log in.
■ Users cannot access applications or data.
■ File systems cannot be mounted.
■ Disks or file systems become full.
■ Data is lost.
■ File systems become corrupted.
■ Users cannot access network services.
■ Users cannot access printers.
■ System performance decreases.
■ System becomes unresponsive.
By regularly monitoring system performance and use, maintaining good
administrative records, and following the guidelines in this chapter, you can limit
the scope and severity of problems.
