At the last 2 weeks we stood rebalancing our ScaleIO environment (280 TB raw) for SDS device migration between nodes.
We're removing the SDS devices from one server, waited for rebalance, inserted in another node, configured it using perccli, delivered to Linux (/dev/sd*) then added again in SIO.
Is there a cleverer way to do that? Like just remapping the drives in ScaleIO (maybe after a perc foreign import at destination node). I didn't try to remove it "in hot state" from source and inserted in destination node, but since ScaleIO is smart with "actual path" inside the same node, may it can handle that.
