Hello, all.
From what I understood after reading many documents/blog posts on this subject, One given ESX server will think it is isolated when:
1. It can't receive the heartbeats from the other ESX servers
2. It can't ping the default gateway of the service console network.
I decided to add a second service console network, on the vmotion vmnic, to get rid of the "no redundancy" message.
I read on many places that I will need to set a gateway, or a pingable device on this second network. Is this true? I currently don't have a gateway for this network, because there is no need to route the vmotion traffic to anywhere else.
Won't the servers find themselves isolated only AFTER not seeing eatchother on both SC networks and after not pinging the default gateway on the first service console network?
If I really need to set up an Isolation address on network2, should I set das.usedefaultgateway to off and das.isolationaddress (or is it das.isolationaddress1?) to the gateway of the first SC network and das.isolationaddress2 to a pingable network device on SC network2?
Thanks in advance.

if its just to get rid of the no redundacy message you can add this to the advanced options of HA
das.ignoreRedundantNetWarning True
yes you will need to add a isolation address. just set an additional "das.isolationaddress", the default isolation address(gateway) can still be used and doesn't need to be disable, on the secondary service console network.
Then do a "reconfigure" for HA on every host.
But of course you can also add a 2nd NIC to your service console.

if all you want is to get rid of the redundancy messages, why not just add a second vmnic to the current service console instead of creating another one?
Thank you for your replies.
I wanted to get rid of the message, but also wanted to grant that the SC was redundant.
I configured the second SC network without a gateway, then I asked the network people to create a pingable IP in this network and added this IP to das.isolationaddress.
