8. Repeat Steps 4 and 5 to check the logical drive and physical drive status.
After resetting the controller, if there is a false bad drive, the array automatically starts
rebuilding the failed logical drive.
If the array does not automatically start rebuilding the logical drive, check the status
under “view and edit Logical drives.”
■
If the status is “FAILED DRV,” manually rebuild the logical drive. Refer to the
SANnet II Family RAID Firmware User’s Guide for more information.
■
If the status is still “FATAL FAIL,” you might have lost all data on the logical drive,
and it might be necessary to re-create the logical drive. Proceed with the following
procedures:
a. Replace the failed drive. Refer to the SANnet II Family FRU Installation Guide for
more information.
b. Delete the logical drive. Refer to the SANnet II Family RAID Firmware User’s
Guide for more information.
c. Create a new logical drive. Refer to the SANnet II Family RAID Firmware User’s
Guide for more information.
Note –
As physical drives fail and are replaced, the rebuild process regenerates the
data and parity information that was on the failed drive. However, the NVRAM
configuration file that was present on the drive is not recreated. For details on restoring
the NVRAM configuration file to the drive, refer to the
SANscape CLI User’s Guide .
Rebuilding the logical drive restores the RAID integrity to a self-consistent state. This
does not guarantee that the data has not been corrupted. All possible application checks
should be performed to ensure that the data is not corrupted before it is used for
business or production purposes.
For additional troubleshooting tips, refer to the SANnet II 200 SCSI Array Release
Notes .
7.6 Using the Reset Button
To test that the LEDs work, using a paperclip, press and hold the Reset button for 5
seconds. All the LEDs should change from green to amber when you perform this test.
Any LED that fails to light indicates a problem with the LED. When you release the
Reset button, the LEDs return to their initial state. See Chapter 5 for more information.
To silence audible alarms that are caused by component failures, use a paperclip to
push the Reset button. See “Silencing Audible Alarms” on page 6-4 for more
information about silencing audible alarms.
