ATTO Technology SC 5700 operation manual Drive Diagnostics, Read only drive test

6.2 Drive Diagnostics

You may determine the performance of drives attached to the FastStream using various displays and tests in ExpressNAV Storage Manager.

The following instructions assume you have already set up at least one RAID group.

The ATTO FastStream collects various metrics to measure performance for physical drives attached to the FastStream during normal system operation and drive initialization and verification.

New performance data is updated every 60 seconds which impacts performance slightly, even if you minimize the browser window. Exit the ExpressNAV Storage Manager completely whenever you need maximum performance.

Preliminary steps

1If you are not already in the ExpressNAV Storage Manager, type the IP address of your appliance in a standard browser. On the splash screen, click Enter Here. In the box provided, type in your user name and password, and click OK.

2The Health and Status Monitor page appears. Click the Diagnostics button on the left hand menu.

3Select the operation you wish to perform from the next menu presented.

Note

Identify SES Elements is not available for the FastStream SC 5300 model.

Read only drive test

The read only test performs a non-destructive scan over the entire surface of each drive to identify bad areas of the disk drives and determine read performance. It may be run while data is passing through the FastStream.

Running this test may negatively impact performance. Once the Read-only test has completed, system operation returns to normal.

To fix errors on disks, use the Initialize and Verify Drives process as described in Ensure Drive Integrity on page 11.

1Follow the instructions in Preliminary steps above.

2Click the Read-Only Drive Test button.

3Click Next.

4If no drives appear in the information box, click on the System Scan button.

If drives are available, click on the drives you wish to test; the drives are highlighted.

5Click Commit.

6A warning box appears. In the warning box, verify that you want to complete the configuration by clicking on Yes. Clicking on No ends the procedure without making a change.

If you chose to do a read-only test, the Drive Performance and Health page appears showing what tests are running and their results. You may select other tests to run or continue on to other tasks.
