Thanks for the time you spend here.
Let me explain my activities.
The controller was connected to an IRF stack of H3C switches using two 1g links. They used ports g0/0/0 and g0/0/1 on the controller and showed as PC1
A new stack of switches win TenGig Interfaces was installed, and I created a lacp bundle PC2 using interfaces g0/0/2 and g0/0/3. I created the PC2 trunk wit its switchhports shut, and for migration i Shut the switchports of PC1 and unshut the ones for PC2.
Everything was fine. A few days later the troubles began showing the error messages from above. I have not been onsite last week, So I cannot tell what happened in detail. but the discrepancy in the config of the two trunk members is obvious.
I will run the command you recommended when I am back onsite and report the output.
Cheers
Albert
