Splunk Add-on for EMC VNX: Why am I getting an "OSError: [Errno 2] No such file or directory" in data_loader.log?

Thanks in advance for any answers.

It's looking for something that it can't find -- this add-on needs a number of EMC specific steps to be completed on the forwarder before it will work properly, I suspect one of those either didn't complete properly or ended up in a location that is not findable in $PATH / not readable due to permissions.

We have completed all the steps before configuring addon and the above Error still exists. But we are able to see Vnx_file but not vnx_block. Is this issue resolved for anyone.
