We had experience this situation on server with the dual paths showing the unlicensed mode. We had to execute the following to fix the errors.
Note: symptoms are after you upgrade the power path / the license key might have been removed / license wouldn't have taken into effect if its already added , then we need to try the below. if you add the license key and reboot the server should pick its optimal policy automatically, if doesn't we need to try the below.
1. powermt check_registration
2. powermt set policy=so dev=all (eg so is for symmetric device , co is for clarion for other storage system its ad .)
3. powermt display dev=all
4. powermt save (Save configuration.)
