I checked the views and they give only what I can see in OEM. Unfortunately I don't have the create diskgroup statements because I stamped and added them to the diskgroup via asmtoolg, a gui-like tool that does all the work for you (another reason to do things yourself). I'm still researching this, I'll let you know what I find. I've seen others that lament this difficulty too, so I guess it's a known problem. Received on Wed Jul 01 2009 - 12:16:51 CDT
