I had to edit multipath.rules distributed with Multipath; I removed the colon between the major and minor device numbers provided as arguments to /dev/devmap_names. Oila, /dev/lun[0,1,2] appeared as links. Here are the contents of /etc/udev/rules.d after the edit: # multipath wants the devmaps presented as meaninglful device names # so name them after their devmap name KERNEL="dm-[0-9]*", PROGRAM="/sbin/devmap_name %M %m", NAME="%k", # -----------------------------------------------^ notice, no colon SYMLINK="%c" Vince Virgilio ************************************ This e-mail and any files transmitted with it are proprietary and intended solely for the use of the individual or entity to whom they are addressed.
