> The names in /dev/mpath are now > the WWID the mpath* names are indeed just that, user friendly names, not to be used for creating LVMs. The /dev/dm-* (device mapper names) are the ones that should be used instead. Also in /etc/multipath.conf there is a section where you can specify the WWID and provide an alias. This alias will show up on your multipath -l command. I think you have to start udev service, restart multipathd service and possibly run partprobe for the userfrienly names to show up, although I am not sure of the sequence of the commands. So to recap, 1. add aliases for WWIDs in multipath.conf file 2. use dm-* while pvcreating (pvcreate /dev/dm-12, vgcreate vg_test /dev/dm-12) 3. make sure multipath -l is showing user friendly names hth, -Shashank -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
