Diagnostic Tools

A variety of diagnostic tools are available as operating system services and as part of the Backup product. This section describes some diagnostic tools that are useful with Backup.

Diagnostic Report

Backup includes a script called nsr_support that generates an exhaustive diagnostic report. Typically, you run nsr_support only at the request of SunSoft 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 > /temp/filename

For further information about the nsr_support command, refer to the nsr_support man page.

Communications Tests

To verify that communications sessions can be established, test with ping and rpcinfo, which are tools provided with the operating system software.

Because Backup 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. For instructions on using ping and rpcinfo, see "Client-Server Communications ".

Contact SunSoft Technical Support for more tools on testing communications.
