Disneyland and Knott's Berry Farm both had to shut down rides while they checked them for saftey. Most rides were back up and running by late afternoon.
I don't know about the backstage or infrustuctre at DL.
Most of the OC faired well enough that I don't suspect much damage at the parks that couldn't be easily repared, though I did hear that the Abe Linclon in storage was decapitated.
