Thanks for the extra information. When the switches are stacked they act as one logical switch. So then when you connect them together with a LAG you are basically creating a loop and plugging a switch into itself. Unstack the switches and just use the LAG for the switch interconnection, and you should see the LAG go active.
We are using the information provided from the following document: i.dell.com/.../dell-networking-n4000-series-switch-configuration-guide-for-equallogic-sans.pdf We have two N4032F switches that are stacked and have pretty much followed this document word for word.  We are not using DCB.  We are trying to configure a LAG and followed step 2.11 in the document but it appears the LAG is not working.   Switch 1: interface range fortygigabitethernet 1/1/1-2 no spanning-tree portfast channel-group 1 mode active Switch 2: interface range fortygigabitethernet 2/1/1-2 no spanning-tree portfast channel-group 2 mode active  However, when we view after changing these settings it shows them as inactive.
