Assuming this is not a "Core" installation of 2008 R2, it "should" just run, unless of course it is performing a system check.
What's odd is that there is not a 7.3.6 listed for your system (now that I know which one) ... I wonder if 1) they somehow misplaced the update, or 2) OMSA is somehow wrong in thinking that there should be a newer version, thinking that it should be the same as the adapter/integrated/modular versions, when there may not actually exist a newer version for the embedded H200 on the blades.
Anyone from Dell shed some light on this? Is the update missing or is OMSA confused?
