I want to apply iscsi65sp6 to a 2-node NW cluster with shared storage on
a NW65 server over iscsi. All servers are patched to SP6 and I have
applied the latest winsock patch (wsock6m).

Does the iscsi patch need to be installed on all the servers, or just
the shared storage server? I seem to recall that iscsi was installed
only on the shared storage server originally (Oct 2005).
