HA issue

[kopper27]

hi

I have 1 cluster with 3 hosts and I have another empty cluster

I am adding a new host no shared storage configured yet.

My issue is when I add the new host to the cluster with existing hosts HA cannot be configured

error:

Cannot complete the configuration of the HA agent on the host. See the task details for additional information. Misconfigura-

tion in the host network setup.

but when I add my new host to the empty cluster I got no errors and hosts is properly configured

what is the problem?

thanks a lot

HA does a preconfiguration check to determine if the management networks of all hosts in the cluster are on the same subnet. Looks like the new host you are adding is on a different subnet. HA can work across subnets as long as they are reachable from each other. To override this check, set the das.bypassNetCompatCheck HA advanced option to true and re-configure the host.

well they are in the same VLAN 104 or I have to change that?

That should be fine. Can you go the details section of the failed task and see if there are any related events or other details?

after adding on /etc/hosts

the other hosts IP / DNS Names it working

is that OK?

Ah, ok so it wasn't a subnet issue, just old DNS. Yeah, that's fine
