Starting the System Exerciser

When the System Exerciser is selected from the FUNCTION SELECTION menu, another
menu displays all devices to be tested. Pressing the Enter key starts tests for all of the
devices.
The time required to test all of the devices depends on the number of devices to be tested
and can range from several minutes to approximately one hour for a fully loaded system.
Because some devices require less time to test than others, the number of times a device is
tested under the System Exercise may be one or more.
Note: If the system contains tape devices, CD–ROM, or diskette drives, you will be asked
whether you want to use media in the devices when you are testing.

Display Screens

If the console is a graphics display, normal test patterns are displayed during the tests. After
the graphics adapter test is finished, the standby screen is displayed.
If the console is an async terminal, the standby screen will be displayed during testing. The
time–of–day will be displayed at the top of the screen and is updated approximately every
minute.
After all devices have been tested at least once, a results screen will be displayed until
either the Enter key is pressed to restart the System Exerciser or the Exerciser is stopped.
If no errors were detected, the results screen displays the No trouble found message; if
errors have been detected, the results screen displays a list of devices with corresponding
errors.

Stopping the System Exerciser

Although the System Exerciser can be stopped at any time, it is best to stop it while the
results screen is displayed. Stopping the Exerciser at other times can cause the loss of test
information.
When the System Exerciser is stopped, the screen displays all tested devices with errors
flagged. Selecting a device that has an error flag provides details such as SRN, location
code, number of times the device was tested, and the number of times an error was
detected.

Using the System Exerciser to Check Out Repairs and Intermittent Problems

The System Exerciser can be used to check out the system following repairs and to identify
intermittent problems.
When the System Exerciser is running, most built–in error recovery procedures are turned
off. This can cause occasional errors to be reported that normally have no effect on system
operation. Parts should only be replaced when the following occurs:
A high number of errors are reported in relation to the number of times the device was
tested.
Errors reported by the System Exerciser are in the same area as that reported by the
customer.
