Public bug reported:
I have recently been playing with the multipath-tools on an Ubuntu 7.10
AMD64 system. The Ubuntu server is connected to an IBM DS3400 fibre
channel array for the purposes of testing. I have created the
/etc/multipath.conf file which I will attach to this bug report. When I
attempt to run the kpartx -a /dev/mapper/<multipath_name> I get the
following.

I have attempted to reboot the system and checked my libraries it all
seems to be in order. Here is a few bits of out of my system which may
assist.

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 7.10
Release: 7.10
Codename: gutsy
I find it rather odd as all three multipath devices are configured the
same way, however only the R1-1 device actually works and can be
mounted.
I will attach the configuration files for multipath in a moment.

James
