Collecting data for general Linux on IBM Z and IBM LinuxONE problems

Edit online
Collect diagnostic data when a problem occurs. Then submit the diagnostic data to IBM® Support. Whatever the problem, start with this general collection of data as soon as the error occurs, preferably before a reboot of the system.

About this task

The diagnostic data that you collect, and the sources from which you collect that data, are dependent on the type of problem that you are investigating. A base set of information is typically always required. For specific symptoms, you might need to collect additional problem-specific data.

When you submit a problem to IBM Support, you must provide a base set of information.

Procedure

To collect general diagnostic data:

  1. Collect the base set of diagnostic information by using dbginfo.sh.
  2. Depending on your distribution, also collect distribution-specific information:
    • On Red Hat Enterprise Linux, run sosreport.
    • On SUSE Linux Enterprise Server, run supportconfig.
    • On Ubuntu Server, run sosreport.
  3. If the Linux® system runs as a KVM guest operating system, collect the diagnostic data from the KVM host and the KVM guest.
