Actually multipath will report to OS two or more LUNs, OS will explain them to
independent disks, if you doesn't config any mpxioxxx driver. So we can add
each disks into lvm md modules, and put them together to be an one disk
(/dev/md/xx). Because they are from same LUNs, so we can't build them to
be RAID, mirror or stripe/concated, but we can implement a md modules named
multipath, it is very similar concated, but size. I will try to survey that.
But I am not very familiar to the source of stripe/concated, if you can provide
any document for stripe.c and stripe_ioctl.c. Like structure information.
