Troubleshooting VDDK error 16053

Challenge

VMware backup jobs fail after update 3, whereas prior to update they have been working.

  • The jobs are using Network transport mode
  • Source Proxy is Windows 2008SP1/Windows 2008R2

The error message for all jobs in the GUI looks like this one:

Processing VM_Name Error: Failed to open VDDK disk [datastore] VM_Name/VM_Name.vmdk] ( is read-only mode - [true] ) Logon attempt with parameters [VC/ESX: [hosname.local];Port: 443;Login: [administrator@vsphere.local];VMX Spec: [moref=vm-ref];Snapshot mor: [snapshot-ref];Transports: [nbd];Read Only: [true] failed because of the following errors: Failed to open disk for read. Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}.

Solution

This issue is related to some of the dll files in the Windows ZIP file for VDDK 6.5 with incorrect manifests, making them depend on two Visual C++ 9.0 versions, both 9.0.32709.4148 and 9.0.21022.8. This causes a failure to load vixDiskLibVim.dll with error code = 0x36b1, which means side-by-side configuration is incorrect.

Workaround

Edit failing jobs and configure them to use a proxy running Windows 2012/2012R2/2016 proxy.

 


Note: The steps to Verify and Correct this issue below are to be performed on the proxy which was used by the failing job.

Verify issue matches this KB:

  1. On the source proxy navigate to Veeam logs location (default %ProgramData%\Veeam\Backup)
  2. Open the folder that matches the name of the failing Job.
  3. Find the log file matching the nomenclature Agent.Job_Name.Source.VM_Name.vmdk.log.
  4. Open the file with any text editor and search for:
    VDDK error: 16053 (One or more required subsystems failed to initialize)

    Example snippet:
    [DD.MM.YYYY HH:MM:SS] < 12620> cli| ERR |Command 'Open' has failed.
    [DD.MM.YYYY HH:MM:SS] < 12620> cli| >>|VDDK error: 16053 (One or more required subsystems failed to initialize). Value: 0x0000000000003eb5
    [DD.MM.YYYY HH:MM:SS] < 12620> cli| >>|--tr:Failed to open virtual disk [Test_Vol1_LUN3] TEST/TEST.vmdk (flags: 4)
    [DD.MM.YYYY HH:MM:SS] < 12620> cli| >>|An exception was thrown from thread [12620].
  5. To further confirm, open event viewer and in Application logs search, Source: 'SideBySide' Event ID: '35'
    example event:
    eventvwr

How to correct this issue:

  1. Open Programs and Features and verify that Microsoft Visual C++ 2008 Redistributable Package (x64) is not installed.
  2. Download and install Microsoft Visual C++ 2008 Redistributable Package (x64) (https://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=15336)
  3. Ensure that no other jobs are running, and reboot the proxy.
  4. Retry failed jobs.
