After changing HBA it is not visible through Powerpath

Hello,

We have changed an HBA. I have reconfigured the zoning and verified that the HBA is registered right on the storage system and that the HBA connections are listed in the storage group connectivity status.
However powerpath don't see the second hba.
How can I make this hba visible to powerpath? powermt check didn't worked.

thanks in advance.
best regards
Manfred
