Article ID: 8082
Reviewed: 28/08/2020

Product Version:
AhsayOBM : 8.3.4.0 or above
OS: Windows

Problem Description

When performing a VMware guest VM backup in VDDK mode on VMware vCenter/ESXi v5.0 and v5.1. The following error message is received in the backup report:

No. Type Timestamp Log
* info ... ...
* erro YYYY/MM/DD hh:mm:ss Fail to connect VM disk by VDDK library" error: "VDDK Mode Error Virtual Machine = "VM/Hard disk" Reason = "Fail to connect VM disk by VDDK library. Error=Unknown
* ... ... ...

Cause

The VMware VDDK 7 API used in AhsayOBM v8.3.4.0 or above no longer supports backup in VDDK mode for VMware vCenter/ESXi v5.0 and v5.1

Resolution

To workaround this issue replace the current VDDK 7 API with VDDK 6 API. Download the VDDK v6 API files from here

  1. Stop the AhsayOBM services.

  2. Stop the AhsayOBM NFS service.

  3. Make a copy of the current folder %OBM_INSTALL%\bin\x64.

  4. Using Windows Explorer open folder %OBM_INSTALL%\bin\x64.

  5. Delete the following 13 .dll files from the %OBM_INSTALL%\bin\x64 folder.
    • diskLibPlugin.dll
    • libexpat.dll
    • lookup-types.dll
    • msvcp120.dll
    • msvcr120.dll
    • pcre.dll
    • sqlite3.dll
    • ssoclient.dll
    • vddkVimAccess.dll
    • vim-types.dll
    • vmacore.dll
    • vmomi.dll
    • zlib1.dll
  6. Unzip the downloaded vddk.zip file and copy the contents %OBM_INSTALL%\bin\x64 folder.

  7. Start the AhsayOBM services.

  8. Start the AhsayOBM NFS service.

After the VDDK 7 API files are replaced with VDDK 6 API files. AhsayOBM v8.3.4.0 or above installation will no longer support backup of VMware vCenter/ESXi v7 backup sets.
