Wow, that's a pretty specific requirement.

If this is the case, it is a requirement of NetApp, as it is not required
by Oracle.
iSCSI works fine without ASMLIB. I will supply the caveat that I have done
this on Oracle Linux 5.5, not 6.
Even so, it seems unlikely to be a requirement for anything other than
NetApp.

You probably need to create a Proof of Concept environment, and try it.
