Uploading core dump files

When a core dump file is saved, an event message is generated. If the AutoSupport service is enabled and configured to send messages to Lenovo support, an AutoSupport message is transmitted, and an automated email acknowledgement is sent to you.

Before you begin

  • You must have set up AutoSupport with the following settings:

    • AutoSupport is enabled on the node.

    • AutoSupport is configured to send messages to technical support.

    • AutoSupport is configured to use the HTTPS transport protocol.
      Note
      Beginning in February 2023, Autosupport data transmitted using HTTP will no longer be accepted.

      The SMTP transport protocol is not supported when sending messages that include large files, such as core dump files or sending AutoSupport messages to technical support.

About this task

You can upload the core dump file through the AutoSupport service over HTTPS by using the system node autosupport invoke-core-upload command, if requested by Lenovo support.

  1. View the core dump files for a node by using the system node coredump show command.

    Example

    In the following example, core dump files are displayed for the local node:
    cluster1::> system node coredump show -node local
    Node:Type Core Name Saved Panic Time
    --------- ------------------------------------------- ----- -----------------
    node:kernel
    core.4073000068.2013-09-11.15_05_01.nz true 9/11/2013 15:05:01

  2. Generate an AutoSupport message and upload a core dump file by using the system node autosupport invoke-core-upload command.

    Example

    In the following example, an AutoSupport message is generated and sent to the default location, which is technical support, and the core dump file is also sent to the technical support:

    cluster1::> system node autosupport invoke-core-upload -core-filename
    core.4073000068.2013-09-11.15_05_01.nz -node local

    In the following example, an AutoSupport message is generated and sent to the location specified in the URI, and the core dump file is uploaded to the URI:

    cluster1::> system node autosupport invoke-core-upload -uri https//files.company.com -core-filename
    core.4073000068.2013-09-11.15_05_01.nz -node local
