Issue/Introduction
The SDDC manager precheck gets stuck at 46% for long or fails with the below error:
A problem has occurred on the server. Please retry or contact the service provider and provide the reference tokenEnvironment
VCF 5.0.x
VCF 5.1.x
Cause
This is a known issue where the vCenter session had expired before the discovery phase of the precheck workflow completed.
Resolution
- Take a snapshot of the VC server.(Do not skip this step). Please refer to "Snapshot Best practices for vCenter Server Virtual Machines" and "VMware vCenter in Enhanced Linked Mode pre-changes snapshot (online or offline) best practice" for more information.
- SSH to the vCenters using root user and enter shell mode if required
shell
3. Edit the vapi endpoint configuration
vim /etc/vmware-vapi/endpoint.properties
4. Find session.maxSessionIdleMilliseconds and increase its value. The default value is 1h, i.e. 3600000 ms. Increase it to 2h i.e. 7200000 ms. (Make sure to remove the # at the beginning so it takes effect.)
session.maxSessionIdleMilliseconds=7200000
5. Restart the vapi-endpoint service by running following command.
service-control --stop vmware-vapi-endpoint && service-control --start vmware-vapi-endpoint
6. Ensure the service has started successfully by navigating to:
https://vc_hostname_or_IP/vapiendpoint/health
After the value is increased, run precheck again.
Additional Information
Please ensure there are no errors/warnings on the workload, if so please resolve those before running the precheck.
