You can skip hosts while applying an ESXi update to the management domain or a VI workload domain. The skipped hosts are not updated.

Procedure

  1. Using SSH, log in to the SDDC Manager VM with the user name vcf and password you specified in the deployment parameter sheet.
  2. Type su to switch to the root account.
  3. Retrieve the host IDs for the hosts you want to skip. 
    curl 'https://SDDC_MANAGER_IP/v1/hosts' -i -u 'username:password' -X GET -H 'Accept: application/json' |json_pp
    Replace the SDDC Manager IP address, user name, and password with the information for your environment.
  4. Copy the ids for the hosts you want to skip from the output. For example:

    In this case, the id for esxi-2.vrack.vsphere.local is b318fe37-f9a8-48b6-8815-43aae5131b94.
  5. Open the /opt/vmware/vcf/lcm/lcm-app/conf/application-prod.properties file.
  6. At the end of the file, add the following line:
    esx.upgrade.skip.host.ids= host id1 , host id2
    Replace host id1 and any other host ids with the information from step 4.
  7. Save and close the file.
  8. Restart the LCM server by typing the following command in the console window:
    systemctl restart lcm

Results

The hosts added to the application-prod.properties are not updated when you update the workload domain.
