Overview
NTT Software Innovation Center (SIC) is undertaking promotion of open innovation centering on the development of open source platforms, collaborative service development with NTT operating companies, and other R&D. NTT SIC is playing an active part in various open source projects including OpenStack, Hadoop, PostgreSQL and Linux kernel.
As the technology thought leader, NTT SIC required a flexible network that allowed rapid innovation and was simple to operate while controlling their TCO.
Challenges
The team at NTT SIC was experiencing growing layer 2 complexities like network loop, rogue DHCP servers, mis-configuration of IP addresses, and wanted to adopt a network architecture that addressed these challenges. The ability to build and rapidly deploy custom applications was of paramount importance. The solution had to be able to easily integrate with their existing software stack and leverage custom applications like GoBGP
As multiple operational teams depend on NTT SIC, the R&D team was working on tight SLAs and could not spend cycles provisioning and managing their network. They needed a reliable yet simple network infrastructure that allowed collaboration and rapid innovation.
Introduction:
NetWorker is a back-end solution which works predominantly on a computer network. Data from a production server will be backed up to NetWorker server over the network.Any problem with the network may break the backup, cloning or recovery job. The NetWorker Troubleshooting Tool (NTT Tool) has been developed to help NetWorker users identify any potential network problem which may affect NetWorker functionality. This KB Article explains the NTT components and provides a brief overview of it.
NetWorker Troubleshooting Tool, the GUI overview:
Description:
This version of NTT support NetWorker 8.2.x, 9.x, and 2018.x releases. Network Troubleshooting Tool (NTT) is a simple and easy to use the tool (GUI driven) and it is expected to greatly help our customers and partners in reducing the time taken to install and configure NetWorker server.
Supported OS platforms:
- Windows 64bit (Windows 7 / 8.1 / 10, server platform 2008R2, 2012, 2016)
- Linux 64bit (RHEL7, CentOS ver.7)
- The NTT do not support NetWorker NVE since this is under SLES and no GUI. (Workaround: to run NTT on a NW storage node or client)
- NOTE: the next version of NTT 1.0.7+ will have support for SLES Linux distribution.
NetWorker Troubleshooting Tool installer incorporates 3 tools into one GUI interface. Following sections explain these tools in detail

Network Validation Tool (NVT) for NetWorker - (Testing network connectivity of a NetWorker Datazone).
NSRPCHK - NetWorker Proactive check tool - (Provides configuration resource overview, it report most common NetWorker problems and warnings from logs).
NSRGET - (Provides log gathering and reporting for issues. Also include a device probe utility for tape).
NVT for NetWorker
Network Validation Tool for NetWorker (NVT) initiates series of tests on the network to check connectivity among various computer systems where NetWorker is going to be installed or where NetWorker is already running. User need to input details of the hosts to be validated. In an existing NetWorker environment tool can read NetWorker installed hosts information from NetWorker DB and populate in tool s UI. If the user wanted to test environment before installing NetWorker, hosts details need to enter on Tool s UI manually. DNS and NTP server details also need to be entered into the tool. After entering input details a user can initiate validation. At the end of validation, a summary table will be displayed with success or failure message against each test ran by the tool. From the validation summary, the user can identify any existing network related issues which will affect NetWorker backup. The user can take action to rectify network problems.The NVT validations are:

- Host availability on the network
- DNS resolution (forward and reverse lookup)
- Network Time Protocol (NTP) access
- The 'nsrrpcinfo' test to all nodes in the data zone
NSRPCHK
NetWorker server proactive check tool version 1.3 is command-line diagnostic binary made by EMC Field support resources for EMC support resources or partners with the main objective:
Report very brief NetWorker configuration information (the NSRDB)
Search for most common NetWorker server problems in Media DB, Client file index, daemon log area.
To automate the time-intensive review of EMC Networker logs.
Report possible Operating System tuning configuration based on NetWorker best practice guide.
