HA agent has incompatible networks

[AllBlack]

Hello,

I am seeing this error on node 3:

HA agent on <host> in <cluster> has an error incompatible networks:

Cluster has networks missing: 130.185.120.230: 10.75.120.230

On node 1 and 2 I have no such problem.

I can verify that DNS is correct. Time is synced too.

For some reason the networking setup has disappeared from vCenter.

It is still all there in console

esxcfg-vswitch -l

On the other node it is the same

esxcfg-vswitch -l

I am able to vmkping the network it is reporting missing. We upgraded to vCenter 2.5 U4 recently

Could you try to remove and re- add the host to the cluster

I think you will get this message when all the portgroups on a vSwitch (or maybe all vSwitches) don't match between hosts. This happened to me in my test lab, one of the hosts has a lot of extra VLANS (portgroups) on one of the vSwitches. I added the das.allowNetwork0 option to the HA advanced settings and that fixes this problem.

Check out this KB article:

Hi,

One of the host had two additional vswitches so I removed them. Also added das.AllowNetwork0.

It is not working and now I get the following error

-Unable to contact primary HA agent

-HA agent on node 1 has error

-HA agent on node 1 has error No valid networks were found for HA on this node. Check to see if anu of 0 are available on this node

This happens on all 3 nodes. When I remove das.AllowNetwork I get the original error on just one node.

I haven't had the chance to remove and re-add node

remove the node from the cluster, or even better remove it from vcenter. but first make sure it's absolutely the same(network) as the other hosts.
