Hi, thanks for the advice. The upgrade is already scheduled, but I would like to fix this issue before proceeding with a big upgrade (unless an upgrade will fixes the problem). The problem is on all hypervisors. We have 2 cluster (both connected to the same storage system): - the old one with FC - the new one with FCoE With dmesg -T and looking at /var/log/messages we found several problems like these: 1) [Wed May 3 10:40:11 2017] sd 12:0:0:3: Parameters changed [Wed May 3 10:40:11 2017] sd 12:0:1:3: Parameters changed [Wed May 3 10:40:11 2017] sd 12:0:1:1: Parameters changed [Wed May 3 10:40:12 2017] sd 13:0:0:1: Parameters changed [Wed May 3 10:40:12 2017] sd 13:0:0:3: Parameters changed [Wed May 3 10:40:12 2017] sd 13:0:1:3: Parameters changed [Wed May 3 12:39:32 2017] device-mapper: multipath: Failing path 65:144.

Looking at host logs, I found also these locking errors:

I'm using Fibre Channel or FCoE connectivity; storage array technical support has analyzed it (also switch and OS configurations), but nothing has been found.
Is this on a specific hosts, or multiple hosts? Is that FC or FCoE? Anything on the host's /var/log/messages?
Any advice?
Thanks
