Finding PowerVault info in OME

I can't find much info about disk enclosures such as MD1420s in OME4. In OME 2.5 it was all there under the servers they were attached to. There's nothing there when I click on an enclosure in OME4 other than the backplane and emm version. In particular, it would be nice to have the enclosures service tags somewhere. Is it that I'm not discovering devices properly, or is that just how the software is?
