## Starting physical drive self-test verification tests

Use this action to perform the following physical drive self-test verification tests:

- Short test. This test completes in two minutes or less.
- Extended test. This test lasts for the duration of a complete physical drive verification test.

These self tests validate whether a physical drive is functional. If a drive is marked defunct, this action might provide additional information that IBM service representatives can use to diagnose the problem.

If a physical drive supports self-test verification tests, the Information panel for the selected physical drive (that is, the right panel) displays the row Last self-test result.

1. Click a physical drive , a SCSI channel , a logical drive , or a controller from the Main Tree.
2. Click Actions --> Physical drive self tests --> Start short self test to perform a short test.
   or
   Click Actions --> Physical drive self tests --> Start extended self test to perform an extended test.

   The self test starts and the Information panel displays a progress indicator labeled Self-test percent completed. When the self test completes, the progress indicator disappears and Last self-test result is updated. Last self-test result is not updated until the self test completes or you choose to stop the self test.
   Note: If you use this action on a SCSI channel, logical drive, or controller, the ServeRAID Manager starts tests on all the physical drives that support self-test verification tests and belong to the selected SCSI channel, logical drive, or controller.

During the self test, the ServeRAID Manager receives events. When a physical drive fails a self test, the Manager receives an event for each drive that failed. When all tests are complete, the Manager receives the event "The drive self tests are complete."

You can stop a self test before it completes by clicking Actions --> Stop self test.

Results of the previous 20 self tests are stored in the disk drive log for each physical drive tested. To save these results:

1. Click the controller from the Main Tree.
2. Click Actions --> Save printable configuration and event logs. The ServeRAID Manager saves the self-test results for all the physical drives that support the self test in the file RAIDN.LOG.
