I googled up `hpsa` and got a screenful of "Health Professional Shortage Area."  I'm pretty sure `hpsa` isn't that.  It could be "HP Service Activator," or it could be "HP Smart Array," or it could be "Hippo Party Sunday Afternoon," although that last one seems unlikely.  ;)

It's possible that you might need a more descriptive tag, like `hp-smart-array` or `hp-service-activator` (or the thing that the tag really refers to that I guessed wrong).  That would be more useful, and also less likely to be deleted by HopelessN00b.
