Wear an anti-static wrist strap attached to an unpainted metal surface on the rack or chassis when handling parts.
Only trained customer personnel should perform this procedure.
  1. If necessary, log on to https://access.teradata.com and initiate an incident.
  2. Obtain a replacement part as described in Obtaining a Replacement Part.
  3. Contact the system administrator if you do not know the host name or IP address of the designated host CMIC (SMWeb 12.06 and later) or SOV-enabled CMIC (SMWeb 12.05 and earlier).
    In SMWeb 12.05 and earlier, you must access the home page of a CMIC that is SOV-enabled. If the CMIC is not SOV-enabled, most web applications and pages are unavailable. If this occurs, you must navigate to the SMWeb home page of an SOV-enabled CMIC. For more information about the SMWeb home page, see SMWeb online help or the Teradata Server Management Web Services User Guide (B035-5350) available at http://www.info.teradata.com.
  4. Remove the new part from its packaging and place it on a static-free surface.
  5. Record the serial number and/or part number of the new part in the site equipment log.
  6. Using a browser, connect to the Server Management Web Services home page by typing the following in the Address field of the browser:
    CMIC Version Home Page Address
    SMWeb 12.06 and later: http://<hostname or IP address of CMIC or Teradata ServiceConnect connection>:9981/CWA/home.asp
    SMWeb 12.05 and earlier: http://<hostname or IP address of SOV-enabled CMIC>:9980/CWA/home.asp
  7. On the Server Management Web Services home page, click Server Management Client.
  8. If prompted, log on to Server Management Client as a Service User. The Server Management Client software opens.
  9. Identify the node containing the failed storage drive:
    1. In the Server Management Client window, click the Summary Alerts tab.
    2. In the Summary Alerts tab, open the alert summary folder containing the failed drive.

      In the Synopsis field, the following alert indicates a failed drive:

      A Node Drive Failure has been detected in SMP.x.x.x.x.x.x
      SMP.x.x.x.x.x.x identifies the failed storage drive. The first x is the system ID, the second x is the collective ID, the third x is the cabinet ID, the fourth x is the chassis ID, the fifth x is the backplane ID, and the sixth x is the drive ID.
      Chassis ID numbers are shown in the cabinet build illustrations.
  10. If you have a multi-system configuration, in the Server Management Client Tree View, in the System pull-down menu, select All.


  11. Above the System pull-down menu, click Hide normal chassis status. The node with the failed storage drive appears in the Server Management Client Tree View.
  12. Verify that the node in the Tree View matches the node in the summary alert:
    1. In the Tree View, expand the node with the failed drive. indicates the failed drive.
    2. Expand the Disk Backplane.

    5. In the Properties window, in the Alias row, find and record the system ID, collective ID, cabinet ID, chassis ID, backplane ID, and drive ID.
      The system ID, collective ID, cabinet ID, chassis ID, backplane ID, and drive ID also appear along the top of the Properties window.
    6. Click Close.
  13. Open a Maintenance Window. This prevents alerts from being forwarded to Teradata Services at sites that are TVI-connected.
    1. In the Server Management Client window, click the node containing the failed drive.
    2. In the Server Management Client window, select Functions > Maintenance Window. A Maintenance Window dialog box appears.

    3. In the Maintenance Duration field, set the Start Time and the End Time. Start Time is the date and time the Maintenance Window opens, and End Time is the date and time the Maintenance Window closes; the default is four hours.
    4. At Name, enter a name for the Maintenance Window.
    5. Click Activate.
    6. In the Information dialog box that appears, click OK to acknowledge the Maintenance Window has been saved. If more time is needed to complete the procedure, extend the duration of the open Maintenance Window: change the number of hours in the Maintenance Duration field and click Activate.
  14. Click the node to highlight it.
  15. Click Functions > Locator LED. The Locator LED Enabled window appears. In the cabinet, the LED of the affected node illuminates.
  16. At the front of the cabinet, locate the drive with a solid amber or blinking amber LED.
    Drives 0 and 1 are OS drives and are not customer replaceable. If the blinking LED appears on either of these drives, contact Teradata customer services.
    If the node has more than one drive with a solid or blinking amber LED, notify Teradata customer services. Use a contact method that is in accordance with your service contract.
