I think it's most likely to be either an ACL on the NetApp box (with a 
misleading "Invalid TargetName" error message meaning "Invalid Target for this 
Initiator"), or possibly NetApp is sulking because the usual (but technically 
optional) ":xxxxxxxx" trailing portion of the iSCSI IQN is missing.

When you find out what causes it, please feel free to update 
http://ipxe.org/2c0d603b with some helpful NetApp-specific hints.  :)
