Error unregistering UCS domain from UCS Central

[#1]

I cannot remove a UCS domain from a UCS Cental 

Tried un-registering via the GUI in UCSM and inside UCS Central and get this result

Then tried doing it from the CLI on the UCS fabric interconnects (following the Cisco docs) and get this error

The error text is "Error: Update failed: [Create-only and naming props cannot be modified after creation, class=policyPolicyScope, prop=defaultPolicyName"

Can't find out what this means

Any ideas anyone?

Looks like a bug CSCva66540. I will work on publishing external facing release notes.

Please attempt this workaround and confirm it resolves the issue:

Here is the work-around.

1.     Edit the Host Firmware Package Policy. Un-select the Blade Version and Rack Version.
2.     Unregister from UCS Central.

Attempt to set the default and global-default host firmware packages to null for blade or rack bundle and unregister. This will have no impact on existing servers using this policy, however, I would conduct this during a maintenance window to be safe.

Server Tab > Policies > Host Firmware Packages > NAME > Modify Package Version

Very helpful - that worked

Thank you
