MSA2040FC - IO traffic only on controller A
Hello,
I have strange problem with MSA2040FC on customer site. To this array are connected directly two linux hosts. Array has two storage pools, on each pool is configured one volume. Multipathing is configured correctly, on both volume I can see IO on volume statistics but I see IO traffic only on A1 and A2 ports, not B1 and B2.
Pool configuration below. Volume configuration, IO statistics and multipath in attchement files.

Do you have any idea why I dont observe IO on B-ports?
