Doesn't look like there's any disk activity.
To create my volume group I first built and initialised my raid, then I went to config. -> volume manager -> Vol. Group, I selected the unit that had shown up and clicked new volume group.
I've not been into the volume group to set up size etc yet.
here's a screenshot
I'm out - I never even noticed such a status there! Maybe the DSS is trying to create a software RAID? Nevertheless, not having major disk activity is definitely a sign of a problem here - have you contacted open-e support yet? If not, you should do so.
