The March 2007 Issue of the IBM Systems Magazine has a workaround that allows you to "dynamically expand rootvg" disks located on mirrored VIO servers. The workaround is needed because the command "chvg -g rootvg" on the client does not pick up the LV size change on the VIO server ("extentlv").
The IBM Systems Magazine is located at http://www.ibmsystemsmag.com/ME2/Default.asp Search for "Dynamically expand rootvg", or the March 2007 issue of the magazine.
Thanks to Steve Pittman for suggesting this tip.
