Ok, I can now DEFINATLY say this is an MS iSCSI Initiator issue.
I tested with open-iscsi and now the connection re-instatement works both
ways, tested like 10 failovers and no disconnect! :-)

Used same pacemaker config like before.

Still weird why MS initiator only works one way. Guess I have to ditch MS
in my setup.

Kind regards,
Caspar
