How to find VMware API version used?

[MortenSeeberg]

We are discussing a matter with VMware support, and they want to verify which VMware VDDK is being used by NetBackup (backup hosts Unix and Windows performing VMware backups), is there a matrix documenting this or a way to verify the version used on the backup hosts?

I would like a universal solution, so I know this for future reference as well...

hi 

it looks like you are looking for this, it explines the supported version for VDDK with netbackup

http://www.symantec.com/business/support/index?page=content&id=TECH145168

Problem

As vStorage/vADP backups environments come in many versions, it is always a good idea to verify that the version of Virtual Center and/or ESX is supported by VMware for vStorage backups.

Solution

NetBackup uses VMware Virtual Disk Development Kit(VDDK) to backups Virtual Machines using vStorage.  As VDDK  versions increase, NetBackup may eventually follow.  To identify if your environment is support please review the VDDK  Release Notes.

Here is the release notes for version 1.1.1:
http://www.vmware.com/support/developer/vddk/VDDK-1.1.1-Relnotes.html

NetBackup versions and VDDK  versions:

NetBackup 7.0 - VDDK 1.1.1

NetBackup 7.0.1 - VDDK  1.1.1

Here is the release notes for VDDK  1.2 which is included in NetBackup 7.1 to 7.1.0.2:
http://www.vmware.com/support/developer/vddk/VDDK-1.2-Relnotes.html

Here is the release notes for VDDK 5.0 which is included in NetBackup 7.1.0.3 to 7.5.0.4:
http://www.vmware.com/support/developer/vddk/VDDK-500-ReleaseNotes.html

Here is the release notes for VDDK 5.0 Update 1 which is included in NetBackup 7.5.0.5 to 7.6:
http://www.vmware.com/support/developer/vddk/VDDK-501-ReleaseNotes.html

To determine the version of VDDK that NetBackup is using, please check the version information of the following file:
C:\Program Files\Common Files\VERITAS\VxMS\Shared\VDDK\plugins\disklibplugin.dll

This information can also be found towards the beginning of the VxMS log

I wonder how Google missed that tech note when I was searching this morning :) Thank you Nagalla.

I would also like to know how to verify this on Linux, will try and see if I can find anything on this.

OK, found the plugin on SLES/Appliance:
/usr/openv/lib/shared/vddk/plugins64/libdiskLibPlugin.so

# strings libdiskLibPlugin.so  | grep release

---cut--

*_release_bora_614080

which is the same build number as Windows Library has, so I think that confirms the build number.
