SFCFSHA 6.2 : DG in unknown status

Hi all, On a 2 nodes system I did a fresh installation of SFCFSHA 6.2.
There's an IBM array with shared Luns. There's only one path.

Linux are 6.7 64bit built identically.
After installation, llt failed to start.

So I installed also the MR and patch : sfha-rhel6_x86_64-MR-6.2.1 sfha-rhel6.7_x86_64-Patch-6.2.1.100
Then llt is starting, the cluster is up and I finished to configure it with disk fencing.
Good.
But as soon as I add a DG and the FS (only one on this dg) resources in VCS, the DG appears with a question mark and the "unknown status".
And I see this error message coming repeatedly :
2016/02/18 15:29:22 VCS ERROR V-16-2-13040 (mynode1) Resource(cvmvoldg1): Program(/opt/VRTSvcs/bin/CVMVolDg/monitor) was abnormally terminated with the exit code(0x8b).

Following a post about this error I verified the files in /etc/VRTSvcs/conf/types.cf and /etc/VRTSvcs/conf/config/types.cf and copied the most recent one on the other (stopping cluster, copying files, starting cluster).
No positive results.

Trying to start the resource group lead to a message saying the group cannot be starting since it had probes pending on both nodes. I also tried with one node with no more success.

Any advices ?

Here's some informations :
# vxdg list
