Appliance for Hadoop
Hardware Servicing
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 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
  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. For a Hadoop data node, verify that Ambari or Cloudera Manager shows the node in a healthy state:

    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
  8. On the Server Management Web Services home page, click Server Management Client.
  9. If prompted, log on to Server Management Client as a Service User. The Server Management Client software opens.

    2. In the Summary Alerts tab, select the summary alert containing the failed drive.
    3. Select Locate Components. Server Management highlights the targeted node in the Tree View.
  11. Open a maintenance window:
    1. With the targeted node highlighted, select Functions > Maintenance Window.

    2. In the Name field, enter a name for the maintenance window.
    3. For Duration , either accept the default of four hours or set the Start Time and End Time.
    4. Click Save.
    5. In the Information dialog box, click Close.
    If more time is needed to complete the procedure, extend the duration of the open maintenance window by changing the number of hours in the Duration field and clicking Save.
  12. With the targeted node highlighted in the Server Management Client Tree View, select Functions > Replace FRU.
  13. In the Replace FRU window, select Chassis component and click Ok.
  14. If necessary, click the tab with a failed icon.

  15. Select the numbered red icon identifying the failed storage drive. The FRU Replace window appears.

  16. At the Replace FRU window, click Ok to proceed.
  17. Click Ok at the next window to turn on the locator LEDs.
  18. At the front of the cabinet, locate the drive with a solid amber or blinking amber LED.
    If more than one drive in the same node has failed since the initial summary alert, you can now replace all failed drives in that same node.
