Now i have the failover deactivated on one open-e server (no1) and only the volumes on the iscsi target configured.

Open-e Server:
bond0 with IP 192.168.2.220
failover-target1 + vol00(LUN0) + vol01(LUN1) + vol02(LUN2)

on exsi (with vmkernel network 192.168.2.200) i see all LUNs (0,1,2)

Only in failover with virtual IP are the LUNs not working/not to see.
