5.6 Interpreting User Environmental Test Package (UETP) OpenVMS Failures
If the cause of an error is not readily apparent, use the following methods to
diagnose the error:
•
OpenVMS Error Log Utility
—Run the Error Log Utility to obtain a
detailed report of hardware and system errors. Error log reports provide
information about the state of the hardware device and I/O request at the
time of each error. For information about running the Error Log Utility,
refer to the
OpenVMS Error Log Utility Manual
and Section 5.2 of this
manual.
•
Diagnostic facilities
—Use the diagnostic facilities to test exhaustively a
device or medium to isolate the source of the error.
5.6.1 Interpreting UETP Output
You can monitor the progress of UETP tests at the terminal from which they
were started. This terminal always displays status information, such as
messages that announce the beginning and end of each phase and messages
that signal an error.
The tests send other types of output to various log files, depending on how you
started the tests. The log files contain output generated by the test procedures.
Even if UETP completes successfully, with no errors displayed at the terminal,
it is good practice to check these log files for errors. Furthermore, when errors
are displayed at the terminal, check the log files for more information about
their origin and nature.
5.6.1.1 UETP Log Files
UETP stores all information generated by all UETP tests and phases from
its current run in one or more UETP.LOG files, and it stores the information
from the previous run in one or more OLDUETP.LOG files. If a run of UETP
involves multiple passes, there will be one UETP.LOG or one OLDUETP.LOG
file for each pass.
At the beginning of a run, UETP deletes all OLDUETP.LOG files, and
renames any UETP.LOG files to OLDUETP.LOG. Then UETP creates a
new UETP.LOG file and stores the information from the current pass in
the new file. Subsequent passes of UETP create higher versions of UETP.LOG.
Thus, at the end of a run of UETP that involves multiple passes, there is
one UETP.LOG file for each pass. In producing the files UETP.LOG and
OLDUETP.LOG, UETP provides the output from the two most recent runs.
If the run involves multiple passes, UETP.LOG contains information from all
the passes. However, only information from the latest run is stored in this file.
Information from the previous run is stored in a file named OLDUETP.LOG.
