Environment

VMware vCenter Server 8.0.x

VMware vCenter Server 7.0.x
VMware vCenter Server 6.7.x

Cause

• This is caused if in the source vCenter the update manager service is stopped when the upgrade was performed

 

Resolution

• Check the status of update manager service

# service-control --status --all command

If it is not running try to start the service and troubleshoot in case of any errors

Update manager service may go in stopped state even if started with service-control --start vmware-updatemgr command

Investigate /storage/log partition using below kb article:

vCenter log disk exhaustion or /storage/log full

Additional Information

• vCenter upgrade will fail at stage 2 pre-upgrade check
