Jobs Failing with Error: "Task 'Reconfigure virtual machine' failed" -
Description
When backing a VMware system agentlessly or updating a virtual standby, the job fails with error message:
Replay.Common.Implementation.Virtualization.VSphereApi.EsxRemoteException: Task 'Reconfigure virtual machine' failed... For more details open events on ESXi host/vCenter.
The error is complemented with additional information such as the following:- Task 'Reconfigure virtual machine' failed: Another task is already in progress.
- Task 'Reconfigure virtual machine' failed: Operation timed out.
- Task 'Reconfigure virtual machine' failed: A general system error occurred: Error deleting disk. Device or resource busy.
-
Cause
Issue is caused by VMware either not accepting or denying the API request to perform necessary actions required by the core to perform its functions. This is most often due to a virtual center is does not meet recommended specs by VMware (recommended not minimum) or by virtual centers and/or ESXi hosts that are out of date on VMware patches. -
Resolution
To resolve the issue, please update the virtual center and ESXi hosts to updated builds of the installed VMware version. Also verify the recommended technical specifications for your virtual center (specifically the amount of memory). Keep in mind that the minimum RAM requirement is for running the virtual center and does not take into account third-party integration with VMware, which is what agentless backup jobs and virtual export utilize.
A reboot of the ESXi host/s could also correct the problem. After the systems are restarted and fully functional, reboot the Core server to force the system to re-authenticate with the virtual environment.
