vSphere 4 and ESXi 4 HA errors

I am having trouble enabling HA on the new ESXi 4 and vSphere 4 environment on my IBM BaldeCenter S environment. Everything was working perfect untill i activated DPM on aggressive mode. DPM powered down all hosts except one ruuning all the VM's. Now since then the HA agent is not configuring properly.

I receive the following errors when i try to enable HA on the cluster.


HA agent has an error : cmd addnode failed for
secondary node: Internal AAM Error - agent could
not start. : Unknown HA error
error

Administrator

HA agent has an error : Cannot complete the HA
configuration
error
5/27/2009 1:59:51 PM
Administrator


I have tried everything from disabling and re-enabling HA, Creating a new cluste and DataCenter, entering hosts in maintainance mode and then exiting, disconecting the hosts and removing then re-adding, installing frest ESXi and vCenter servers, changing network parameters, reconfiguring for HA.


I have manually edited the host file and entered the entries for all esx hosts. All esx hosts and vCenter can ping each other through IP, FQDN and short names.


Any help would be highly appretiated. I am totally out of options.


Best regards,


Adeel Akram

Have you fixed also /etc/opt/vmware/aam/FT_HOSTS?

Have you reinstalled the HA agent (using VIC)?

Hi Andre,

Thanks for the quick response.

if i give the command "vi /etc/opt/vmware/aam/FT_HOSTS" on one of my 4 x ESXi 4.0 hosts, i receive an empty file with text input. Do i need to enter text in this file as well as i did for "/etc/hosts" file?

How do you reffer i install the HA agent through VIC. If you are refering to right clicking the host and clicking reconfigure for HA and un-checking and checking HA and DRS in the cluster settings. Then yes, i did bot that.

Best regards,

Adeel Akram

Sorry, I forgot that you have ESXi.

Try:
/opt/vmware/aam/VMware-aam-ha-uninstall.sh

Then reinstall the HA agent.

Issue resolved.

In my case the problem was that i had manually entered the host file entries for all ESXi servers but i did not make an entry for the vCenter.

As soon as i made an entry for the vCenter on the host file of each ESXi server. Disconnected the hosts from the cluster and re-added with HA and DRS enabled. The issue was resolved.

All blades except for one? hmmmm, that's not a good thing in terms of High Availability. Are you sure?

Have your tried to reinstall the HA agent?
The inventory in VC cluster is fine? Or there was also some old host names?

Well in my case this initially solved my problem. But this time i had
all entries in my host file correct and still could not resolve the
issue. So enabling HA and DRS one by one solved the issue for me.


Wierd things happen with HA in ESX. :-)

solution: hi, had the same error on ESXi 4 but don´t want to use the "unsupported" mode for changing the /etc/hosts file. in my case the FQDN in the "search domains" was not the full one. after changing this and restart everything works fine. Also i had to check all dns entries (hosts, vcenter and so on).
