I'm trying to backup several VMs and all the attemtps finish by the same general error 156. 

Looking to the 2 attached log files does not help me to locate the problem

I actually ran into this recently at a customer, the issue is with the Permissions of the vmware account you are accessing vsphere with.

Please ensure you have DataCenter down permissions as documented in this article.

I find it much much easier to just create a user and add it to the Administrator group.

Best of Luck,

Thanks Doug.

I use built-in account "root" with "Administrator" role for connection NBU to ESX server and he has got all the permissions. I re-apply permissions to whole Inventory tree - no change.

does it ever woked , or its a new configureation?

are you able to Browse and select Virtual machiens in the policy?

did you make sure that you have entered valid  Vcenter or ESX username and passwd in Netbackup?'s picture

Thanks Nagalla.

It is new installation vmware backup has never worked here.

Yes, I'm able to browse and select VM. I tested manually and by query too.

I hope my username and password are correct, my credentials were accepted by creating "Virtual Machine Servers" in NBU Credentials. I use the same u,p for vSphere Client to ESXi connection.

Are you able to create manual snapshot? Does it work? If it doesn't there is no way NBU will.

Your logs are showing exactly same error message as per this TN

Your log errors:

I agree with Douglas, please check your permission again and try the manual snapshot.

Error code 6 in VIX API represents VIX_E_NOT_SUPPORTED(The operation is not supported).

fault.RestrictedVersion.summary is also logged in bpfis log.

15:12:14.793 [3320.3476] <2> onlfi_vfms_logf: INF - vmwareLogger: SOAP 1.1 fault: "":ServerFaultCode [no subcode]

Which edition of vSphere are you using? Does it really support VADP?
