RHEL and Fedora support this via the standard mkinitrd script, but only if you set the multipathing up at install time (start installer with "linux mpath"). For other distros, ymmv, but you'll need to get the multipath commands included in the initramfs image and add script to activate all the maps that are needed for the root file system. Regards, Bryn.
