Multipath with a DELL MD3000i

[gob]

Hi

I am struggling to get multipath working with Proxmox 4 Beta and a DELL MD3000i over iSCSI. I haven't tried with Proxmox 3 but I assume it isn't a beta issue and just me not grasping it.

I think I am getting close to the goal. The first issue I find is the following errors after running multipath -ll

# multipath -ll

Although the multipath seems to see the four paths to the SAN, I am a little worried about the errors at the start of the output.
Here is my multipath.conf:

blacklist {
        
        device {
                vendor DELL
                product "PERC|Universal"
        }
}
devices {
        device {
        user_friendly_names     yes
                vendor                  DELL
                product                 MD3000i
                hardware_handler        "1 rdac"
                path_checker            rdac
                path_grouping_policy    group_by_prio
                prio            rdac
                failback                immediate
        }
}
multipaths {
        mulitpath {
                device {
                        vendor DELL
                        product MD3000i
                }
        }
}

Ignoring those errors I have tried to create a volume mapped to the multipath devices but I get:

# pvcreate /dev/dm-3
  Device /dev/dm-3 not found (or ignored by filtering).

dm-3 amd dm-4 do exist in /dev
Anybody know what I am missing?

thanks
