It was just disabled it as we now had another method in the scsi core code to get ALUA info. My plan would be - based on this series - to not attach DH just when using native SCSI multipath for a device. > If it allowed device handlers to get attached, these two > developement efforts (native scsi multipath and refactoring the alua > support) could go on in parallel. > > Or am I missing something here? It just seems to be about this DH stuff is that there is bad history there and no more users are wanted. But now I am getting bogged down in this ALUA support because of that, which I feared would happen. Thanks, John
