Environment

Vmware Cloud Foundation 4.5
VMware Cloud Foundation 5.x

Cause

When VCF upgrade fails at CAP Upgrade stage, it fails to resume on retry due to left over CAP upgrade files from previous failure.

Resolution

To resolve the issue, run CAP cleanup workflow prior to resuming upgrade.

Follow the below mentioned steps to run CAP cleanup:

  • Get an SSH session to the SDDC Manager and switch user to root.
  • Remove vcf-cap-worklfows.json file 
  • rm /var/log/vmware/capengine/vcf-cap-workflows.json
  • Register a user credential with the following shell commands:
  • echo -n <password> | /usr/lib/vmware-capengine/scripts/user_registry.sh add -u apiuser
  • authHeader="Basic $(echo -n "apiuser:<password>" | base64)"
  • echo $authHeader

This will output the encoded credential.

 

Sample output:

  • Start the CAP cleanup workflow:
curl --location --request POST 'http://127.0.0.1:15051/capengine/api/v1/workflow/execute' \
--header 'Content-Type: application/json' \
--header "Authorization: $authHeader" \
--data-raw '{
"workflowName": "cap-update-cleanup",
"operation": "start"
}' | jq

 

Sample Output:

  • Re-trigger upgrade from SDDC UI.
