Legato NetWorker diagnostic tools
A variety of diagnostic tools are available as operating system services and as part of the Legato NetWorker product. This post describes some diagnostic tools that are useful to diagnose issues with Legato NetWorker.
To verify that communications sessions can be established, test with
rpcinfo, which are tools provided with the operating system software.
As Legao NetWorker relies heavily on mapping of ports, use
rpcinfo to test the operation of the portmapper. Using
ping tests the connection up to the network layer in the OSI model;
rpcinfo checks for communication up to the session layer.
Legato NetWorker includes a script called
nsr_support that generates an exhaustive diagnostic report. Typically, you run
nsr_support only at the request of Legato Technical Support. Redirect the output of the script to a file and then e-mail the file for analysis. To run the script and redirect the output, become root on the system and enter the
nsr_support command at the shell prompt:
# nsr_support > /tmp/filename
For further information about the nsr_support command, refer to the nsr_support man page.
- The support gathering script (
nsr_support) is missing from 7.4 base install and from 7.4sp1/7.4sp2 product patches - This is currently under investigation.
- As a workaround I recommended you copy over the
nsr_supportfiles from an older release into the nsr directory on to your EBS/NW 7.4 system. Use the following table to download the corresponding files/README for the desired platform.
Notes: The windows binary (nsrsup.exe) has only been copied from NetWorker 7.3 media and not tested. (dependancies on other binaries/libraries may exist)
