Well this is Linux (Suse)and not AIX
We have the 2 vio servers

But I already have found (after 2 weeks searching on the internet) the solution (on the redhat site the solution for SuSe, RH is the best  ).

You must mount by device=id and not by-name. Furthermore you have to put dm-multipath at the INITRD_MODULES in the /etc/sysconfig/kernel file.
Run mkinitrd and maybe run lilo (don't forget to change the root name in device-id instead og by-name)

Well why can't this be standard on linux on Power (maybe it is for RH)

I have a VIO client with SuSe SLES10 SP2 running (standard installation)
I started multipath (/etc/init.d/boot.multipath and /etc/init.d/multipathd

But it seems that i does not work as i expect it to be (see the follwing commands with output)
Can someone tell me wat i am missing/forgetting?
