I am trying to configure ISCSI on my environment. I am attempting to 'test' to present a LUN via ISCSI to our ESXi host. I've added the IQN's on both sides (NetApp & ESX) and ESX resolves the IQN from the IP address of the NetApp ISCSI adapter. When I rescan the ESX adapter I still can't see anything presented. Why?? This is getting beyond frustrating!!
I look forward to your response.

Did you test the process via commandline?
If so, there are chances that you might have missed some steps in between.
The correct process as far as I can remember would be:
make sure that LUN is online
create an igroup, add ESXi's iqn to this i group
map the LUN to this igroup
configure vmkernel port for iscsi traffic on ESX
add target portal to vmware iscsi initiator (!IMPORTANT! - DO NOT use ip address od e0M port on your storage system)
You could avoid a lot of configuration mistakes by using the OnCommand Systemmanager GUI to configure volumes and LUNs on yor netApp storage systems. Its free, and easy to use.
There is a Linux version also available, in case if you are not a fan of microsoft. http://mysupport.netapp.com/NOW/cgi-bin/software/?product=OnCommand+System+Manager&platform=Linux

One more thing: if you have a routed network, the 7 mode option ip.fastpath.enable can create a lot of mess with packet's routing. It can be very difficult to troubleshoot too. Let me know if you find any other thing interesting
