They do, however, show a single controller in evaperf which is what I would have expected. How do you have the preferred path set in Command View? Follow, to receive updates on this topic.

Also, what are you running in evaperf to figure out which controller s your hosts are using? When I run evaperf hc, even my windows hosts are connected to one controller but not both. I have another XEN Pool running v5.

There are two instances of each LUN. Granted, this is an EVA I have so it could very well be different.
But are the LUNs distributed between the assigned controllers? They do, ega, show a single controller in evaperf which is what I would have expected.
Mark this reply as best answer, if it answered your question. When running multipath -ll, I can see the two controllers and all 8 paths but on all the LUNs only one controller is doing all the work: You will be able to leave a comment after signing in. I checked two different resource pools and both are using a single controller.
A LUN will connect to just a single controller in a properly-working multipath configuration, but if you have multiple LUNs and two active controllers, they should be distributed between them. Upvote if you also have this question or find it interesting.

Posted August 13, We are working on a fix. Posted August 15, Yes, I believe we have the correct multipath configuration file.
The multipath -ll from this pool is very different, but to me looks like each path is given equal priority. Apologies for the inconvenience.

For a windows server we can see both controllers being used for the LUN presented to that server using EVA monitoring tools. Sign In feature is currently unavailable and you will not be able to post new content. Follow, to receive updates on this eba.
My physical Windows servers are showing as using both controllers even though the path preferences are set to prefer a path.
