Hi,

I think i was able to make it working properly.

What I did was:

1) in xenserver for each host create 4 network dedicated to the storge ex. 172.10.1.1, 172.10.2.1, 172.10.3.1, 172.10.4.1 and for second host 172.10.1.2---172.10.4.2.
2) doing the same for open-e 172.10.1.10---172.10.4.10 and no team bond at all on both xenservers or open-e
3) put xenserver in maintenance mode and activate support for multipath.
4) edited the file /etc/multipath.conf on both xenserver and added the following as per your pdf/video suggestion on page 59

device {
vendor "SCST_FIO|SCST_BIO"
product "*"
path_selector "round-robin 0"
path_grouping_policy multibus
rr_min_io 100 }
5) also it's important to follow the instruction on page 61 and add on both xenserver the iptables rules on file /etc/rc.local
in my case was iptables-I INPUT -s 192.168.0.230 -j DROP (exclude the management interface from multipath) otherwise multipath will try to establish also a connection on the management interface of your open-e.
6) go back to xencenter and add your iscsi storage...

Thanks for your suggestion
