Test Controller
User interface
User interface
The Test Controller provides for the control of offline diagnostic test
execution. It utilizes a set of parameters to control its operation. The
parameters consist of the following:
• Global set that controls the overall operation of the Test Controller
• Test set (one per test) that controls how the tests are executed by the
Test Controller
• CPU parameters (one per processor) that contain status information
about the tests executing on each processor
All these parameters are in NVRAM.
The user interface allows the user to modify parameters that reside in
NVRAM, thereby controlling the operation of the Test Controller. It also
allows the user to select which subtests are executed on each of the
processors and modify the test parameters, as well as any other test
information.
The Test Controller user interface consists of two basic menus. The first
is the main menu that gives the user the following capabilities:
• Modify the POST boot selection
• Control operation of the Test Controller
• Display the current global parameter selections
• Display processor summary
• Switch processors
• Go to the Test Configuration menu
The second menu is the processor Test Control menu that provides the
following capabilities:
• Select classes of subtests to execute
• Select subtests to execute
• Specify pause enables
• Specify whether or not to loop
• Specify the test and/or subtest error counts
