Safely Decommissioning SCP from an HCI Cluster (Without Getting Locked Out of vCenter)

Had a case recently where a customer had integrated Sangfor Cloud Platform (SCP) with an HCI 6.11.1 R1 cluster, then later decided they didn't need SCP anymore. The problem: they removed the SCP association from the HCI Manager side first, before releasing the resource pool on the SCP side. That order matters more than you'd think.
  
End result: HCI Manager was stuck showing "managed by Sangfor Technologies Cloud Platform" and blocking every vCenter operation, while SCP still showed the resource pool sitting in Error status. Neither side agreed the divorce was final.
  
How we cleared it:
  

  • In SCP, delete all tenant users first, then the tenants themselves.

  • Go to Resource Center → Resource Pools, and delete the resource pool (Super Admin password required to confirm).

  • Go to Resource Center → Nodes, find the HCI cluster entry, and delete it there too.

  • Back in HCI Manager, confirm the "managed by SCP" banner is gone and vCenter actions are usable again.




  
One gotcha: if the resource pool delete keeps failing, check the cluster connection credentials SCP is using to talk to HCI — if they're stale, update them to the current HCI admin login and retry. That was the missing piece in our case.
  
Takeaway: always release the resource pool on the SCP side before pulling the association on HCI Manager. Doing it the other way round is what causes the lock.
