Well, finally i got to expose it to conga, and it was easy. Only i had to do is: pvcreate /dev/mapper/mpath0p1 Once the physical volume exists, it appears in conga when creating a new volume group, so you can choose it. Doing the same on the rest of the nodes i finally could create the clustered volume group and the corresponding gfs2 filesystem, and mount it on 3 nodes. > > I personnaly gave up using conga. > > About HP-DM, there is a OS's shipped solution (on which relies HP-DM!) > called device-mapper-multipath, there's no necessity to use the HP > one. > Uhm, I know, but supposedly it give support for my MSA2312fc ... so i don't know if it would run only with device-mapper-multipath.
