Dear

this time I do not have question but good news:-)
Storewize v3700 and proxmox cluster work out-of-the-box !

the only thing that has to be done is installing multipath-tools and map 
storage to  appropriate SAS adapters on the hosts and that's it !
Failover works as expected  ... VM is running and in the same time 
controller firmwares are being upgraded

There is even no nned for the multipath.conf file because debian has it 
allready "hardcoded" for this type of storage (among the others )

BR

Tonci
