Balance luns across both controllers

I recently had to replace a controller on my EVA 4400. After I replaced the controller I failed back some of the luns to the new controller using Command View 10.1. When I ran EVAperf one the host ports only on controller shows any I/O activity. How can I balance out the load across both controllers?

Re: Balance luns across both controllers

Make sure the multipathing is set up properly on the servers.

Could very well be that the LUNs you failed over are still set to have the non-owning controller as their primary path.

If the non-owning controller gets more traffic to a vdisk than the owning, the LUN will be moved.
