Hi , i've got a problem. (i'm french sorry for mistakes ...)  My configuration is 3 ESXi 4.1, 1 CX4-120 FLARE 30 with Unisphere  CX4-120 iSCSI SPA0 : 10.241.1.160 255.255.0.0 iSCSI SPA1 : 10.242.1.160 255.255.0.0  iSCSI SPB0 : 10.241.2.160 255.255.0.0 iSCSI SPB1 : 10.242.2.160 255.255.0.0  You note that is not the same subnet.  ESXi (example for one esxi) :  vSwitch0 : 1 NIC : 10.241.5.160 vSwitch1 : 1 NIC : 10.242.5.160  My esx is correctly register, i see in Unisphere 4 paths and in ESX-client 4 paths too. I active the ALUA (Failover mode 4). I was install Powerpath in one ESXi and in other one i just use the default NMP with round robin.  The problem is the same, i've got the HAVT Issues Error in Unisphere.  Thank you for your help.
