Procedure

  1. If the host with the faulty component does not belong to a workload domain, retrieve the password of the host.
    1. In a command line window, SSH to the VM on the rack.
    2. Navigate to /home/vrack/bin.
    3. Type the following command:

      lookup-password

    4. Note the ESXi and IPMI passwords of the host that is to be decommissioned.
  2. Decommission the dead host.
    1. If you are decommissioning a qualified host (i.e. if you did not purchase a fully integrated system from a partner), note the BMC password for the host by navigating to the /home/vrack/bin/directory in the SDDC Manager Controller VM and running the lookup-password command.
    2. On the Dashboard page, click VIEW DETAILS for Workload Domain and click the affected domain.
    3. In the PHYSICAL RACKS column, click the physical rack that contains the affected server.
    4. Scroll down to the Hosts section.
    5. In the HOST column, click the host name that shows a critical status (for example, N1 in the example below).
      rack
    6. In the HOST column, click the host name that shows a critical status (for example, N1 in the example below).

      The Host Details page displays the details for this host.

    7. In the HOST column, click the host name that shows a critical status (for example, N1 in the example below).
    8. Note the IP addresses displayed in the NETWORK TWO and MANAGEMENT IP ADDRESS fields.
    9. Click Decommission.

    10. Click CONFIRM.
    11. Monitor the progress of the decommissioning task.
      1. On the SDDC Manager Dashboard, click STATUS in the left navigation pane.

      2. In the Workflow Tasks section, click View Details.

      3. Look for the VI Resource Pool - Decommission of hosts task.

      4. After about 10 minutes, refresh this page and wait till the task status changes to Successful.

    12. For qualified servers, change the password on the host to the common password for ESXi hosts. Log in to the BMC console using the password noted in step a and change the OOB password to D3c0mm1ss10n3d!.

      This step is automated for hosts in an integrated system.

  3. Turn on the chassis-identification LED on the host.
    1. In a web browser, navigate to the OOB IP address that you noted earlier.

    2. Login with your BMC user name and password.

    3. Following the documentation from your vendor, turn on the chassis-identification LED.

    The chassis-identification LED on the host starts to beacon (flashing on and off).

  4. Power off the decommissioned host and remove it from the physical rack. Note the ports on the management and ToR switches it was connected to.

What to do next

Replace the failed component on the host as appropriate and add it back to the rack. See #GUID-47B2C555-3184-40B5-BCA9-86033A717786. For adding a new host, see Add a New Host to a Physical Rack.
