Q
To perform a loopback or a read-write buffer test, fill in the following options in the
Diagnostics tabbed page:
n Data Pattern. This option sets the test pattern. You can select a predefined
eight-byte data pattern, specify your own eight-byte custom pattern, or select
Random Data Pattern. To select your own test data, select Customized from
the drop-down list and enter the data in hex format (0x00–0xFF) into the boxes.
When you select Random Data Pattern, a new random eight-byte pattern is
sent to the devices and/or the HBA, depending on which test is selected
(loopback or read/write buffer).
n Test Increment(s). This option sets the total number of tests to run. You can
enter a test number between 1 and 10,000 in the Test Increment(s) box, or
select the Test continuously check box. If you select Test Continuously, the
number of tests that are run repeatedly is set to 125. If you select Test
continuously but want to stop the test when an error is encountered, select the
Stop on error check box. If you select Test Continuously, a dialog box with a
Stop button is displayed when the test is running. To stop testing, press Stop.
NOTE: The stop action may be delayed if the value entered in the Test
Increment(s) box is large and/or there are a large number of targets
attached to the SAN.
n Test Results. This section displays the results after the test is run. The first
column shows whether the test passes or fails. The remaining columns display
the error counters.
For a loopback test, the test result section has the following information:
q Test Status
q CRC Error
q Disparity Error
q Frame Length Error
For a Read/Write Buffer Test, the test result section shows the following
information:
q Loop ID/Status
q Data Miscompare
q Link Failure
q Sync Loss
q Signal Loss
q Invalid CRC
After making your selections, press one of the following buttons at the bottom of
the Diagnostics tabbed page:
n Click Loopback Test to perform a loopback test.
n Click Read/Write Buffer Test to perform a read/write buffer test.
