Issue/Introduction
The ddpconnchk tool can be used to test the transfer/connection speed from Greenplum to the Data Domain. The ddpconnchk script can not be running in parallel and can only test the connectivity and backup speed for each segment server sequentially. Once you have the result for each segment server you can compare it in order to find any differences in the transfer speed to help identify any issues with the server interface.
Note: Please use it when you experience the slow backups.
Environment
Resolution
Refer to Dell Support KB NetWorker: How to use the DDPCONNCHK tool to test DD ddboost connectivity from NetWorker Hosts
Additional Information
The ddpconnchk tool is not designed to run on all segment servers at the same time. To verify the network saturation issue, please create NFS export on Data Domain and use scp to create a stream for every segment server.
