Identifying HBAs
After an HBA is installed on a host, you can check whether the HBA exists on Device Manager. If the HBA exists, the physical connection of the HBA is correct. Then check whether there is a question mark (?) or exclamation mark (!) on the HBA name. If there is no such a mark, the HBA driver is normal.
