To decommission external PSC:
- Verify all the Management nodes are upgraded to 7.0.
- Power off all nodes in the SSO domain (both external PSCs and the newly embedded PSC/vCenters)
- Take a snapshot on all powered off nodes
- Once all snapshots have been taken, power on all nodes with the exception of the external PSC that is to be decommissioned.
- With the external PSC VM powered off, log in as root to the appliance shell of a converged embedded node.
- To enable the Bash shell, run the shell.set --enabled true command.
- Run the shell command to start the Bash shell and log in.
- Run the cmsso-util unregister command to unregister the stopped Platform Services Controller:
cmsso-util unregister --node-pnid Platform_Services_Controller_System_Name --username administrator@your_domain_name --passwd vCenter_Single_Sign_On_password
Note: You must run this command only on one of the Platform Services Controller replication partners, as the synchronization removes the entries from all other VCSA replication partners.
Note: There is downtime involved in executing cmsso-util unregister command, it will restart the services on the PSC / vCenter Server where you are executing the command.
- Delete the Platform Services Controller appliance that you no longer need from the vSphere inventory.
