Hello,
After enabling jumbo frames in one of our dv switches I got a flood of alerts stating something along these lines:
Event details:
Lost uplink redundancy on DVPorts: "642/d0 c8 0c 50 f0 a6 29 da-e7 fd e6 a1 b7 43 6b 4e", "642/d0 c8 0c 50 f0 a6 29 da-e7 fd e6 a1 b7 43 6b 4e", "642/d0 c8 0c 50 f0 a6 29 da-e7 fd e6 a1 b7 43 6b 4e", "642/d0 c8 0c 50 f0 a6 29 da-e7 fd e6 a1 b7 43 6b 4e", "642/d0 c8 0c 50 f0 a6 29 da-e7 fd e6 a1 b7 43 6b 4e". Physical NIC vmnic3 is down.
These alerts rotate between the hosts, uplinks and dvports.
vmnic3 is not actually going down, so something else is happening.
Hosts are Dell M610 blades
Switches are Dell 8024f with jumbo frames enabled.
Storage is Equallogic PS6510 with jumbo frames enabled.
Dvswitch has two 10G uplinks, 7 hosts and 90vms behind it.
At the point that I changed the MTU from 1500 to 9000 the vmkernels on the dvswitch was set on 1500 mtu as well. Changing the MTU back to 1500 didn't change anything, the problem is still there.
Any ideas?
