ESXi: HA errors and troubleshooting 150 150 Roderick Derks

Just now I got this error when trying to enable HA on a cluster with two ESXi4 hosts:"Cannot complete the configuration of the HA agent on the host. Other HA configuration error."

When experiencing HA configuration issues there are a couple of steps I usually take to try to fix the experienced issues:

  • Click “reconfigure for VMware HA” and see if the issue is still there, if so:
    • Is DNS configured and does it actually work? If not, fix and reconfigure for HA.
    • Is the gateway reachable? If not, fix and reconfigure for HA.

This usually solves 75% of the issues. If it hasn’t been fixed the next step I usually take is unloading the agent and restarting the management services. Although it is pretty rigurous it is the fastest way of fixing HA issues.  In my case I am using ESXi and this is what I needed to do to clean up the host:

  • Disable HA on the cluster
  • /opt/vmware/aam/VMware-aam-ha-uninstall.sh
  • /sbin/services.sh restart
  • Enable HA on the cluster

This solved the issue I had with HA,
