Running the Controller’s Diagnostic Test
During start up, the controller automatically tests its device ports, host
port, cache module, and value-added functions. If you’re experiencing
intermittent problems with one of these components, you can run the
controller’s diagnostic test in a continuous loop, rather than restarting
the controller over and over again.
Use the following steps to run the controller’s diagnostic test:
1. Connect a terminal to the controller’s maintenance port.
2. Start the self test with one of the following commands:
SELFTEST THIS CONTROLLER
SELFTEST OTHER_CONTROLLER
Note The self test runs until it detects an error or until you press the
controller’s reset button.
If the self test detects an error, it saves information about the error and
produces an OCP LED code for a “daemon hard error.” Restart the
controller to write the error information to the host’s error log, then
check the log for a “built-in self-test failure” event report. This report
will contain an instance code, located at offset 32 through 35, that you
can use to determine the cause of the error. See “Translating Event
Codes,” page 4–18 for help on translating instance codes.
