When running InfiniGuard version 3.3.x and above, the InfiniGuard services includes the ability for Backup Admins to use the CLI based “iguard_netcli” tool to troubleshoot or validate network services.

This feature allows Backup Admins to troubleshoot, diagnose, or validate InfiniGuard DDE Networking. The tool allows for various scenarios of Networking diagnostics scenarios between InfiniGuard DDEs and the servers used for protecting data to the DDE shares.

Your TA can assist you in obtaining these tools before they are officially available from the Infinidat Support site. Once you have obtained it, it can then be installed (as an RPM) on any AIX 7.1, AIX 7.2, Redhat or Centos Linux server.

Once installed, the script-based tools allow authenticated access to any 3.3.x or above InfiniGuard version to list and sort contents of any or all of the Deduplication Engine NetBoost Shares. The tool requires a read-only account on the InfiniGuard UI (as a minimum).

  1. Install the InfiniGuard_Netcli RPM on the system you wish to use as a cli tool server to validate networking on InfiniGuard Deduplication Engines (DDEs).
  2. Obtain the RPM appropriate for your host operating system (LINUX/AIX) from Infinidat Support or your TA.
  3. Install the RPM using “rpm –ivh INFINIDAT_InfiniGuard_netcli.rpm
  4. Once installed, you can use the tool to run cli-based Networking tools.

If issues are discovered, the customer team can work with their networking staff and/or Infinidat Support to resolve any issues (thru the normal ticket-based support system). Some examples follow,

The iguard_netcli command will use the –H (or - –hostname) and point to the InfiniGuard DNS-hostname or IP address.  User and Password can be saved to avoid having to authenticate each task.

 This requires “http” access to the ibox floating IP (the System Management IP), and at least a read-only user on the iGuard UI.

The Following example shows several use-case examples of using the iguard_netcli tool to validate networking from the DDE’s to the Backup Server.

Review MTU between Source and Target IPs.

[root@io-wt-11 ~]# iguard_netcli --mtu -H ibox1593 -d1 --src --dst

Review Traceroutes between source and target IP’s.

[root@io-wt-11 ~]# iguard_netcli --traceroute -H ibox1593 -d1 --dst
Traceroute to ( 56 data bytes, 30 hops max
  1            0.13 ms

Iperf testing requires you to run iperf in Server mode on the backup server. This allows for a bandwidth test to be run between the InfiniGuard DDE Target IP and the Backup Server Source IP.

Ex. from Backup Server, start iperf in Server mode.

 [root@io-wt-11 ~]# iperf -s
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)

Example in running netcli to test iPerf Bandwidth

 [root@io-wt-11 ~]# iguard_netcli --iperf -H ibox1593 -d1 --iperf_version=1 --src --dst
Client connecting to, TCP port 5001
