HA stops at 60%

You may have ran into this issue too. You put your host in maintenance mode and when turning back to join your HA cluster again bam it gets stuck at 60% reconfiguring the HA agent… WTF!

Although there are good articles on Internet, i.e here and especially at VMware.com here and here, none of them could solve my problem but at least they gave a good insight of HA service and troubleshooting methodology.

Well with all the readings I still can’t join my HA cluster huh!

I tried RMDIR /etc/opt/vmware/aam but nos success, I tried to remove the HA package but no luck… Looks like the aam/ folder is corrupt somehow grrr….

Then the light came in (sometimes it happens LOL), and what about putting the host in maintenance mode, then remove it from the VMware cluster, reboot the server, add it back to the cluster!?

And indeed it worked great! aam/ folder got deleted, rebooting cleared out memory and any locks, and adding back the host to the cluster and getting out of the maintenance mode recreated properly the aam/ folder and the HA agent started up successfully.

It’s a wonderful virtual world isn’t it 🙂

    This is like similar to my problem. I took the host out of the cluster, upgrade to vsphere, created a holding area folder, while putting back into the holding area, retreiving vcentre agent, it hung, stuck on In progress and that’s it, even after turning HA off and DRS in Manual, still won’t do anything.
    I will be trying something tomorrow and will post back the outcome. I will join the host to another vcentre after rebooting it, put it in maintenance mode, remove from the vcentre and add to the problamatic vcentre (adding the host in maintenace mode!)
