Known Issues

The following are known issues in Neverfail vAppHA V6.1.

  1. Environment
    • Clusters containing a mix of ESX 4.0, ESX 3.x
      • Untested at EAR, vAppHA should not be deployed in a live production environment if the Cluster contains ESX 3.x
  2. Installation Issues
    • Application Plug-ins can be installed post install but this is only possible from a local management client running on the VM
  3. Configuration Issues
    • If ESX 4i Lock Down is used
      • This should not include the user account used by VMAdaptor
  4. Operational Issues
    • Repeated VM Restarts
      • vAppHA will not trigger VMRestarts within 30 mins of a previous VM Restart Action. vCenter time is used to determine whether another restart should occur.
      • If the VM time is more than 30 mins behind the time on vCenter then the server may restart again if a rule fails.
    • VMotion Rule action does not result in a VMotion to a new ESX Host
      • If the specified Resource Pool contains the ESX Host that vAppHA is currently running on then DRS will not request a VMotion.
      • VMadaptor does not warn the user if they configure vAppHA in this way.
    • VMotionAndRestartApplications
      • The message logged does not mention the application restart ‘Finished in t ms with status Migrate VM task’
    • VMotion Rule action fails with an unspecified target error
      • If the Target Host and Resource Pool are left empty
    • Clusters must not contain multiple VMs with the same windows host name
      • Even if the duplicates are in the powered off state
    • Alert events
      • Alerts will state the server host name twice and the role as Active.
    • Time trial license expiry
      • If the license expires, when the application is in the stopped state, then this will cause vAppHA to the remove service protection when upon restart.
      • Ensure that the application is in the started state before restarting vAppHA.
    • The System Tray Icon references Primary and Active server
      • The following states appear next to the tray icon P/- or P/A
  5. Management
    • The vAppHA Management Client Online Help
      • Includes pre screen shots from the Beta version
    • Alerts Panel contains alerts relevant to the Neverfail Heartbeat product
      • Alerts for Switch Over, Fail Over, Full System Check etc are not relevant for vAppHA deployments
