I have a 4 host cluster all running 3.5 update2 110181 and VC 2.5 build 104215
HA and DRS was working fine before the upgrade to update 2 and vc2.5
3 of the 4 are running HA fine but the 4th tries to start the agent and then after 30 sec it says HA agent disabled.
I have checked the aam log vmware_vm5.log it shows no errors but can see the heartbeat from all the other hosts.
I can ping each host with ip and fqdn.
I have removed the host from the cluster and put it back , rebooted the host and recreated the entire cluster, to no avail.
I ran the upgrade to build 110268 ( the version that does not expire on Aug 12), no change.
I can not find any log that gives me any clue to why it is being disabled.
Any other suggestions would be greatly appreciated.
I performed an update this past weekend and ran into the same problem on one of my host, though I had an incompatible network error showing up under the task/events on that particular host. I ended up using the das.allownetwork advanced option to work out my issues.
