As you say lun, I assume you are talking about FC.  Did you increase file system at Linux level too?

If you resize LUN, you need to do steps on Linux too (at least rescan it at minimum - see examples with pvresize, lvresize or whatever fits fs you use). There is plenty of examples you can find using Google.
