I setup a SMHV to testing,

I created a datastore and add hosts into it. When I try to backup the dataset manually.

There enough volume space, I can craete snapshot from CLI and snapdrive.

There have error

===============================================================

My question is, What is Snapmgr INtapVSSRequestor Interface? How to fix the issue?

Is it possible to have a work around ? Without have 2008 R2 running ?

Unfortunately not.. SMHV is not supported on non-windows 2008 R2 platforms.

The reason is that SMHV consume special CSV APIs which is not available on platforms prior to windows 2008 R2.

What's the windows os you are testing SMHV on? The base supported OS for SMHV 1.0 is Windows 2008 R2 RTM editions.

All other windows servers[windows 2008/2003 and client OS can be used to install the SMHV management stations.

For backup /restore of VM to work Windows 2008 R2 is the base requirement, and i think that's the reason for the error.

Thanks a lot,

My version is

OS Name Microsoft® Windows Server® 2008 Datacenter
Version 6.0.6002 Service Pack 2 Build 6002

Does it mean INtapVSSRequestor Interface only contains in Win 2008 R2?

Can you share more information about INtapVSSRequestor Interface with me?

[vkarinta]

Yes, that's correct, please retry your operation on Windows 2008 R2 and let us know if you face any issues..

Thanks,
