Running Controller Diagnostics

Related Topics

Use the Controller >> Run Diagnostics option to verify that a controller is functioning properly.

Procedure

1

From the Subsystem Management Window, select the desired controller, then select the Controller >> Run Diagnostics pull-down menu option from the Controller main menu, or select Run Diagnostics from the right-mouse pop-up menu on the desired controller.

Result: The Diagnostics dialog box appears.

2

Select the checkboxes for all diagnostics you want to run.

3

If you don't want to run the data loopback test on all channels, select a single channel from the list.

4

Select a data pattern file for the data loopback test. Select Use default data pattern to use the default data pattern or Use custom data pattern file to specify another file.

Note: A custom data pattern file called diagnosticsDataPattern.dpf is provided on the root directory of the installation CD. This file may be modified, but the file must have the following properties to work correctly for the test:

  • The file values must be entered in hexadecimal format (00 to FF) with one space ONLY between the values.
  • The file must be no larger than 64 bytes in size. (Smaller files will work but larger files will cause an error.)

5

Select the Start button.

Result: A confirmation dialog box is displayed, containing a text area for describing potential hazards with running the diagnostics, and a text field for you to type in "yes."

6

Type "yes" in the text box, then select OK.

Result: The diagnostic tests begin. When the tests are complete, the status area of the original Diagnostics dialog box will be updated with test results. The test results will contain a generic, overall status message, and a set of specific test results. Each test result will contain the following information:

  • Test (Read/Write/Data Loopback)
  • Port (Read/Write)
  • Level (Internal/External)
  • Status (Pass/Fail)

Note: The results of the Controller Diagnostics also may be written to the Major Event Log, depending on the outcome of the tests. To view the Major Event Log from the Subsystem Management Window, select Storage Subsystem >> View Event Log.
