Hi Mike
That is correct I have had to turn off Active / Active teaming on all dvSwitch port groups as it is the only way I can "resolve" the problem. It is a major step backwards for the ESXi platform. The config I am now using is:
All vm traffic port groups use vmnic0 active and vmnic1 standby and
All vmkernel (management and vMotion) port groups use vmnic1 active and vmnic0 standby. At least this way both 10Gb NICs are being used however not as efficiently as aggregating 20 Gb and letting NIOC do it's thing.
This is major but I have yet to find a real "fix" for this in the VMware KB.
Will also post links to serious bugs in the console network settings check and dvSwitch health check that have cost me days and days of lost time chasing my tail on problems that don't exist because of buggy code.
Stay tuned and please update me if you make any progress.
