Perform Update Precheck

You must perform a precheck before applying an update or upgrade bundle to ensure that your environment is ready for the update.
For an ESXi bundle, the system performs a bundle level precheck in addition to the environment precheck. For VI workload domains using vSphere Lifecycle Manager baselines, the ESXi bundle precheck validates the following.
  • Custom ISO is compatible with your environment.
  • Custom ISO size is smaller than the boot partition size.
  • Third party VIBs are compatible with the environment.
If you silence a vSAN Skyline Health alert in the
vSphere Client
,
SDDC Manager
 skips the related precheck and indicates which precheck it skipped. Click
Restore Precheck
 to include the silenced precheck. For example:
An example of an alert that was silenced in vSAN Skyline Health.
You can also silence failed vSAN prechecks in the
SDDC Manager UI
 by clicking
Silence Precheck
. Silenced prechecks do not trigger warnings or block upgrades.
You should only silence alerts if you know that they are incorrect. Do not silence alerts for real issues that require remediation.
  1. In the navigation pane, click
    Inventory
    Workload Domains
    .
  2. On the Workload Domains page, click the workload domain where you want to run the precheck.
  3. On the domain summary page, click the
    Updates/Patches
     tab. The image below is a sample screenshot and may not reflect the correct product versions.

  6. To see details for a task, click the Expand arrow.
    If a precheck task failed, fix the issue, and click
    Retry Precheck
     to run the task again. You can also click
    Precheck Failed Resources
     to retry all failed tasks.
  7. If ESXi hosts display a driver incompatibility issue when updating a VI workload domain using vSphere Lifecycle Manager baselines, perform the following steps:
    1. Identify the controller with the HCL issue.
    2. For the given controller, identify the supported driver and firmware versions on the source and target ESXi versions.
    3. Upgrade the firmware, if required.
    4. Upgrade the driver manually on the ESXi host and retry the task at which the upgrade failed.
  8. If the workload domain contains a host that includes pinned VMs, the precheck fails at the Enter Maintenance Mode step. If the host can enter maintenance mode through vCenter Server UI, you can suppress this check for NSX-T Data Center and ESXi in VMware Cloud Foundation by following the steps below.
    1. Log in to SDDC Manager by using a Secure Shell (SSH) client with the user name vcf and password you specified in the deployment parameter workbook.
    2. Open the
      /opt/vmware/vcf/lcm/lcm-app/conf/application-prod.properties
       file.
    3. Add the following line to the end of the file:
      lcm.nsxt.suppress.dry.run.emm.check=true
      lcm.esx.suppress.dry.run.emm.check.failures=true
    4. Restart
      Lifecycle Management
       by typing the following command in the console window.
      systemctl restart lcm
    5. After
      Lifecycle Management
       is restarted, run the precheck again.
The precheck result is displayed at the top of the Upgrade Precheck Details window. If you click
Exit Details
, the precheck result is displayed at the top of the Precheck section in the Updates/Patches tab.
Ensure that the precheck results are green before proceeding. A failed precheck may cause the update to fail.
