why friendlyName is empty in get-disk or get-physicalDisk command

I made a storage driver with storport, I am confident that the correct data is returned in the scsi command, but there is no friendlyName in get-Disk(disk type is sas), and get-physicalDisk command also show incorect friendlyName(friendlyName is ‘Generic Physicall Disk’)

by contrast, 'disk driver' in "device manager" showed coreect disk name

I can't figure out what problem is, and how to fix it.
