On the FC initiator, when we are doing a scan we try to narrow the scope of the scan as much as possible, for this purpose we try to get the HBA channel and SCSI targets for an HBA. Unfortunately the mechanism we have implemented to detect these two parameters is not universal and will only work on FC targets that implement a single WWN. This is OK, as the code is capable of operating normally without those 2 parameters, it's just that the filtering on the scan is not as precise as it could be. So the issue is that we are logging as an error when we cannot get that information, which is clearly misleading to anybody reading the logs.
