Products

• VMware Cloud Foundation

Issue/Introduction

• Running precheck/upgrade on environments with Zerto VMs failed at entering Maintenance Mode.

Environment

VMware Cloud Foundation 4.x

VMware Cloud Foundation 5.x

Resolution

To Workaround the precheck:

• Disable the dry run precheck by running the below:
  • Take a snapshot of the SDDC manager VM.
  • SSH to SDDC Manager using vcf and elevate to root with su.
  • vi /opt/vmware/vcf/lcm/lcm-app/conf/application-prod.properties
  • Add the following lines to the end of the file

lcm.nsxt.suppress.dry.run.emm.check=true
lcm.esx.suppress.dry.run.emm.check.failures=true

• save and exit the file: wq!
• Restart the lcm service using below command 

systemctl restart lcm

For the upgrade we will need to power off the Zerto VMs. 

• Follow the below Zerto doc to power off the site. (Please validate with Zerto support before executing the steps in the below article)
