6240 running 8.1.3 and we need to 2 of 5 move shelves from one rack to another. Can I fail over the controller then power down the controller and shelves, move them, power them back on and fail back? I have two shleves I need to move.
If you power down the shelves, any data volumes located on those shelves would not be available. So you would need an outage for those volumes, unless you can clear off the aggregates prior to the move. Are you running 7-mode or C-mode?
