Hi All

many thanks for your replies.
I will update my scenario to ask about adding some devices for stonith
- Option 1
I will ask for having 2 vmware virtual machine, so i can try fance_vmware
-Option 2
In the project, maybe will need a shared storage. In this case, the shared
storage will be a NAS that a can add to my nodes via iscsi. In this case I
can try fence_scsi

I will write here about news

Many thanks  to all for support
Andrea
