You could catch the 'tileerror' event on the layer.
I think that tileerror is relatively new, but I may be mistaken.
It would go something like this:
layer = new OL.WMS(...);
layer.events.register('tileerror', null, function () {
this.setVisibility(false);
alert('oops!');
});

I'm using shaded relief from The National Map as a base layer, but
today it seems that The National Map isn't serving those data, so I'm
getting the infamous pink tiles. I can turn them off manually using a
call to layer.setVisibility(false). But I'd prefer that the users not
have to do this themselves. Is there any way I could write a test in
my Javascript code that would determine whether or not this layer is
really available, and simply make the layer invisible if it isn't?
