On SLES, the symlinks are created by the udev system.  The symlinks are
created by a rule in the /etc/udev/udev.rules file similar to the
following:

KERNEL="dm-[0-9]*", PROGRAM="/sbin/devmap_name %M %m", NAME="%k"
SYMLINK="disk/by-name/%c"

You will probably want to make sure that you have udev installed and
running, and maybe test out that /sbin/devmap_name command to make sure
it works (%M it the major number for the dm device and %m is the minor
number)

Note that there should also be devices in the /dev/mapper directory
with the FC WWN name, iSCSI equivalent, or whatever you have specified
for the alias parameter in multipath.conf.
