Nutanix recommends that you use the Prism Life Cycle Manager to perform firmware updates. However, firmware must be updated manually if:

• The component is located in a single-node cluster, OR

• The component is located in a multi-node cluster, but the hypervisor the cluster is running does not support LCM firmware updates.

• Shutting Down a Node in a Single-Node Cluster

• Shutting Down a Node in a Multinode Cluster

• Manually Updating M.2 RAID Hypervisor Boot Drive Firmware
  Manually update the firmware on HW RAID M.2 boot drives on -G7 or newer platforms in cases when LCM cannot be used.

• Manually Updating Data Drive Firmware
  Manually update the firmware for a SAS or SATA data drive or update the hypervisor boot drive firmware on any -G6 platform M.2 drive (non-RAID).

• Manually Updating SATA DOM Firmware
  Update firmware for a SATA DOM.

• Manually Updating the BMC and BIOS
  Manually update BMC and BIOS versions.

• Manually Updating HBA Controller Firmware
  Update the firmware for an HBA card.

• Manually Updating NIC Firmware
  Manual update for network cards.

• Starting a Single-node Cluster

• Starting a Multinode Cluster

Shutting Down a Node in a Single-Node Cluster

Before updating firmware in a single-node cluster, shut down the node, following the method for your hypervisor.Note: Single-node clusters do not support Hyper-V.

These topics cover single-node cluster shutdown:

• Node Shutdown Prechecks: Node Shutdown Prechecks

• Preparation: Preparing a Single Node for Shutdown

• vSphere Web Client: Shutting Down a Single Node (vSphere Web Client)

• AHV: Shutting Down a Single Node (AHV)

• Node Shutdown Prechecks
  Check to make sure that there are no issues that might prevent the node from being shut down safely. (Even if the node does not need to be shutdown these checks are helpful.)

• Preparing a Single Node for Shutdown
  Prepare the node for shutting down.

• Shutting Down a Single Node (vSphere Web Client)

• Shutting Down a Single Node (AHV)

Node Shutdown Prechecks

Check to make sure that there are no issues that might prevent the node from being shut down safely. (Even if the node does not need to be shutdown these checks are helpful.)

About this task

Estimated time to complete: 5 minutes

Procedure

1. In Prism, go to the Home page and make sure Data Resiliency Status displays a green OK.

2. In Prism, go to the Health page and select Actions > Run NCC Checks.

3. In the dialog box that appears, select All Checks and click Run.
   Alternatively, issue the following command from the CVM:
   nutanix@cvm$ ncc health_checks run_all

4. If any checks fail, see the related KB article provided in the output and the Nutanix Cluster Check Guide: NCC Reference for information on resolving the issue.

5. If you have any unresolvable failed checks, contact Nutanix Support before shutting down the node.

6. Gather component details by running the NCCshow_hardware_info command.
   nutanix@cvm$ ncc hardware_info show_hardware_info
