Can anyone tell me what that means, or where I can look for an answer? I put this server in to Maint. Mode, and I get this error when I exit Maint. Mode and tried to reactive HA on the host.
I have verified that all servers, and VC, can see each other by short name and FQDN.
Have you tried to disable and re-enable HA for the Cluster?
Also, see this post. It might better explain. Was it the Primary you placed into Maintenance Mode?

I did disabled, and then re-enable, HA at the cluster level. It did not fix my problem, unfortunately.
The host was the most recent one added to the cluster, so I am fairly certain that it is not the primary.
Edit:
New message on failure: Error \[10001]: Instance Already Exists

Ever have one of those moments where you just want to slap your self?
I was playing with disk volumes, and had an extra SAN LUN presented to my server. I think that was why it was failing. The other hosts could not see this LUN, so my storage was not visible to all hosts. As soon as I unrepresented the LUN, HA started working again.
I got this message after a vswif problem, subnet misconfiguration, I logged onto the console dropped and recreated both vswifs (redundant vswif), ran the reconfigure for HA and all came good.
I'm running into the same issue, but it's not a vswif issue. I'm just gonna try to rebuild the server.
When you create an HA cluster the first server you insert is the primary. If anything happens to this server HA gets confused
THe fix is a bit messy.
1:Remove all hosts from HA cluster
2: remove clusterring (has to be done to clear out old entries in DB of VC)
3: delete the HA cluster again has to be done to clear out older entries in DB
4: recreate HA and finally add hosts
this should resolve the problem you have
When you say "Remove Clustering" you mean disable HA or something? Or move the hosts out of the cluster?
I'm going to just try a few things but what a PITA. The ESX server that was apparently "primary" (which doesn't make sense, because it was the second machine added) is offline and can't be takin online for now - and the 3rd (and new) box I've installed specifically for redundancy via HA won't enable the HA agent because of this issue.
It's 2008, let's try to build software that doesn't get "confused" eh?
when you are setting HA and DRS the first server you add to it becomes the primary... no idea why the second server became primary...I do not mean remove the cluster I mean remove the server from it and readd them ...
You are basically trying to clear out stuff from the database. Hence the remove and readd bit
This fixed it for me. Kudos! For once, the forums came through!
I'm now getting this on one of the 2 esx servers in our test cluster since I ran update manager on it this morning to pick up the latest updates. I can't migrate anything on to the server either, so I think I'm going to have to rebuild the server. Did anyone else have any problems with the latest set of ESX updates??
This worked for me also - Thanks.
I had this problem as well. While I checked and tried everything mentioned here, I found that the problem with my "rogue" node was actually the hosts file in /etc. The IP for a one of the other nodes was incorrect. I made sure they were all correct and matched up on each node in the cluster. That seemed to take care of it for me.
Thanks for all your posts...all helped point me in the direction to narrow things down.
Well it looks like it's almost a year later.. However, I just ran into the same problem and found this post.
We happen to be talking about this now.. Here's what I have found for this error.
From reading above..
With respect to Primary's the first 5 hosts are all primaries when configured in a cluster. (ESX3.5, VCenter 2.5)
These start with the first host added to the cluster.
If you have 6 hosts and one fails one of the remaining hosts will promote the remaining (6th) host to a primary member.
To view the current primary's for your systems
cat /var/log/vmware/aam/aam_config_util_listprimaries.log
What resolved this problem "No Active Primaries Found" for me was to
open SSH to the host having the problem.
type "hostname" and press return to view the current host name.. (mine was incorrect (not matching the DNS record).
If the host name needs to change you can change this is the VI Client under host configuration, DNS Settings, Host Name
The other way was to open SSH
nano /etc/hosts (Edit/verify the hostname FQDN and shortname) nano /etc/sysconfig/network (edit verify the name) hostname newhostname
Again I had to reboot to fully resolve this so HA would enable.
Hopefully this helps others..

Mark
