Alright, got an interesting issue here. I have an environment that I had up and running for over a month in ESX 3.5 U4 with iSCSI connected to several luns on a Netapp 270 running OnTap 7.3.1.1. I have reloaded those same servers with ESX 4. When trying to get iscsi working, I am having absolutely no luck. My problem is similar to this issue, but I don’t even have paths listed out.

For sanity an hour ago, I loaded 3.5 on one of the servers again, and it connected right up to iSCSI storage. Here are some log entries, 10.1.1.40 is my netapp.

I can have them in the same igroup on the filer, but not matter what, the vsphere server will not connect. This happened on both vSphere installs (until I reloaded the one with 3.5 an hour ago, now it’s fine)
Any ideas?
