Diagnosing a machine panic

Last Updated : May 13, 2024 |

About this task

If a machine panic is detected on your system, you must call the Avaya Services (domestic) or remote (international) support personnel. Avaya Services can request that you deliver the following information:

  • Crash dump from /var/crash/hostname/vmcore.n

  • Namelist from /var/crash/hostname/unix.n

  • Output of the rpm -qa command. For details, see the hardware installation document for your platform.

  • Possibly output from the /var/log/messages file.

To gather all the files for Avaya Services, do the following procedures:

Procedure

  1. Log on as root.
    Important:

    You cannot directly log on as root from a remote connection. You must log on using an administered CMS user ID, then use su - root to log on with root privileges.

  2. Enter: cd /var/crash/hostname

    The system changes to the dump directory.

  3. Verify that unix.n and vmcore.n are present and match the date for the crash in question.
  4. Enter: rpm -qa > rpm_list.out

    The system retrieves the output from the rpm -qa command.

  5. Enter: dmesg > dmesg.out

    The system creates a dmesg.out file.

  6. Enter: cp /var/log/messages messages

    The system copies the output from the /var/log/messages file.

  7. Enter the following command on a single line at the command prompt: tar cvf /storage/cms_crashfiles.tar unix.X vmcore.X dmesg.out rpm_list.out messages

    where the letter X represents the number of the crashdump.

    The system displays a list of all of the files.

  8. Log out of the system.
  9. Notify Avaya Services that the file is ready for download.
