VMware High Availability fails with the error: Misconfiguration in the host Network setup (2003774)

Symptoms

  • Cannot enable or reconfigure VMware High Availability (HA)
  • Enabling or reconfiguring HA fails
  • You see the error:

    Misconfiguration in the host Network setup

  • In the /var/log/vmware/aam/aam_config_util_monitornodes.log file, you see entries similar to:


    07/20/11 12:53:49 [issue_cli_cmd       ] command is '/opt/vmware/aam/bin/ftcli -domain vmware -port 8042 -timeout 5 -cmd listnodes'
    07/20/11 12:53:49 [issue_cli_cmd       ] Trying to talk to self ('<<hostname>>'), yet there is no sites file.
    07/20/11 12:53:49 [myexit              ] Failure location:
    07/20/11 12:53:49 [myexit              ]        function main::myexit called from line 247
    07/20/11 12:53:49 [myexit              ] VMwareresult=failure

  • The /etc/opt/vmware/aam folder contains an invalid configBackup file of 0 bytes

    For example:

    /etc/opt/vmware/aam # ls -lh
    -rw-r--r-T    1 root     root            0 Apr 13  2010 configBackup.tar.gz

Resolution

To resolve this issue:
  1. Review the network configuration in the cluster to ensure that the HA heartbeat interfaces match between hosts.

    • For ESX, HA will heartbeat over all Service Consoles.
    • For ESXi: HA will heartbeat over all VMkernels with the Management Traffic option enabled.

  2. Ensure that there are no extra or missing HA heartbeat interfaces on any hosts.
  3. Ensure that all hosts have the same network configuration on HA heartbeat networks. For ESX, it is the service console network and for ESXi, it is the VMkernel network (With Management Traffic).
  4. Try to reconfigure for VMware HA on the affected host again.
Note: When HA is configuring on a host, it checks that the host network configuration matches any other host in the cluster by comparing HA heartbeat interfaces. ESX and ESXi can be mixed in the same cluster. For more information, see Cannot configure HA for a new ESXi host added to a cluster of ESX hosts (2000907).
