Hi List! I  have searched the Net and i couldnīt find consistent info about it.. Please help. i have review the compatibility information about  IBM storage DS4500 and Linux multipath drivers and i only saw mentions to MPP RDAC multipath. I would like to know if the DS4500 works fine with Linux Device Mapper Multipath (DMMP) or if exist any known issue between them. I also appreciate the recommended entries for /etc/multipath.conf  for the DS4500. Thanks a Lot
