AIX raw device offset

A coworker of mine needs to move a datafile that was accidentally created on a local JFS volume to a shared raw device. He's planning on using dd. Can anyone tell me what the correct offset is for the start of the datafile on an AIX raw device? It's my understanding that AIX writes its own info to the first x bytes of the device, so the Oracle file header needs to start after that.

Sorry, I don't know what version of AIX this is offhand. If that matters, let me know and I'll try to find out.
