ESX 3.5 U3 + Netapp 3020HA + iSCSI - Problems with multiple iSCSI targets

[silicoon]

Hi guys

Basically the setup we have is a dual controller 3020 with full HA cabling using iSCSI as backend protocol for VM storage

Now the issue is that we have 3 storage IPs on each controller in different subnets - only one is used for VMware

I have put the VMKernel in the subnet and added the filers IP ( only the one from the VMware subnet ) as the discovery address ( duh )

Now this is all fine and iSCSI storage is working on all hosts in the cluster but for some reason i am getting failed iSCSI session connections to the other 2 IPs for that controller that i dont even want / need to connect to? - This is happening on all ESX hosts

I tried reconfiguring iSCSI on the ESX host but the same thing happens - its seems as though the Netapp is broadcasting its other addresses and ESX is trying to create another session? Has anyone seen this before?

The target that i am actually using is the IP 10.2.20.208 but as you can see below its trying to create 2 more sessions for 10.2.21.208 and 10.2.1.208
