Disabling LRO on the Host breaks the HA Agent?

[bragazzi]

Following these directions from Cisco to disable LRO on the ESXi host appears to prevent the HA agent from enabling on that host.  When these changes are undone, the HA agent successfully enables as expected.  Obviously, this is not a desired state.

Is LRO on the host required for HA?

Are these directions faulty?

More Information:

Cluster has four hosts, all licensed with Enterprise Plus.  HA and DRS are enabled on the cluster.

When adding the fourth host to the cluster, HA was immediately enabled.  I put it in maintenance mode, made the Cisco-suggested changes and rebooted.

Initially after rebooting and exiting maintenance mode, HA was enabled.  I reconfigured the host for HA and now it presents the "Cannot complete the HA configuration; Other HA configuration error".

Ah-ha!

Disabling HA on the cluster and re-enabling it was successful in enabling the HA agent on all four hosts.  After this, reconfiguring any host for HA was successful.

Had to disable and re-enable HA on the cluster.
