Running RAID Controller Module Diagnostics

Select a RAID controller module, and select Advanced >> Troubleshooting >> Run Diagnostics >> RAID Controller Module.

Select the check boxes for the diagnostic tests to be run. Choose from the following:

• Read Test
• Write Test
• Data Loopback Test

For a detailed description of each test, see Learn About RAID Controller Module Diagnostics.

Important: The Data Loopback Test does not run on RAID controller modules that have SCSI connections between the RAID controller modules and physical disks. The Data Loopback Test will only run on RAID controller modules that have  connections between the RAID controller module and the physical disks.

3

To run the Data Loopback Test on a single channel, select a channel from the channel drop down list.

4

Select a data pattern file for the Data Loopback Test. Select Use Default Data Pattern to use the default data pattern or select 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 might 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 only one space between the values.
• The file must be no larger than 64 bytes in size. Smaller files work but larger files cause an error.

5

Click Run.

6

Type yes in the text box, and click OK.

The selected diagnostic tests begin. When the tests are complete, the Status field is updated with test results. The test results contain a generic, overall status message, and a set of specific test results. Each test result contains the following information:

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

Note: Events are written to the  when diagnostics are started and when testing is completed. These events help you to evaluate whether diagnostics testing was successful or failed and the reason for the failure. To view the Event Log, select View >> Event Log.

Click Close.

Important: When diagnostics are completed, the RAID controller module should automatically allow data to be transferred to it. However, if there is a situation where data transfer is not re-enabled, select the RAID controller module, and select Data Transfer >> Enable.
