Disabling VCHA causing vCenter services to be in stopped status

Products

• VMware vCenter Server
• VMware vCenter Server 7.0
• VMware vCenter Server 8.0

Issue/Introduction

Upon disabling VCHA, vCenter services stops and fails to start with the message "Successfully started profile: HAcore"

Environment

VMware vCenter Server 7.0.x

VMware vCenter Server 8.0.x

Cause

Since the VCHA is broken, the default start profile left for vMon is HAcore and hence it is starting only services related to HAcore profile.

Resolution

Please find the steps below to update the defaultStartProfile

1. Check file
   # cat /storage/vmware-vmon/defaultStartProfile
   
   
2. Output of the file will be similar to
   # cat /storage/vmware-vmon/defaultStartProfile
HACore
   
   
3. Replace HAcore with ALL, using vi editor. The output should be:
   # cat /storage/vmware-vmon/defaultStartProfile
ALL
   
   
4. Restart vCenter services.
   # service-control --stop --all && service-control --start --all
