HA setup issue

[mshaffer]

2 out of the 3 ESX 3.5 servers in one of my clusters fail when I try to enable HA. All 3 servers have the same mem/CPU config and the network config is also the same for all 3. In the summary tab for the cluster the message simply states "Insufficient resources to satisfy HA failover level". The summary tab of the 2 servers that keep failing simply states "HA agent has an error". I have no issues enabling DRS. Thank you.

The first thing that comes to my head is DNS. I would verify that all host in the HA cluster can resolve each other by FQDN and shortname.

Have you checked the logs?

do a "tail -f /var/log/vmkernel" and/or "tail -f /var/log/vmware/vpx/vpxa.log" then Reconfigure HA on the VC. This shoud, at the very least, give you an idea of what's going on.

It was name resolution. I added the FQDN and short names to /etc/hosts on all 3 servers and HA enabled with no problem. Thanks for the help.
