7.4.1.1. Capturing Diagnostic Data from Switches

You can initiate a full system capture using the Switch capture all command to collect the following data:

  • journalctl logs

  • ASIC statedump

  • Currently running firmware

  • Additional system data

The system will poll until completion and package all data into a single compressed *.tar.xz archive for easy transport. Capture files are stored under /tmp/dumps/.

Note

If you want the capture output printed directly to the console, use:

capture all --stdout

To generate and transfer the capture file:

  1. Run the following command

    capture all

    Once complete, the system will output an entry ID (for example, 1).

  2. Using the entry ID from the previous step, copy the capture to your target destination:

    capture copy system <ID> <user@host:/path/to/destination>

    Note

    Alternatively, you can use scp to copy the files. For example:

    scp <BMC_IP>:/tmp/dumps/1/<hostname>_dump_<ID>_.tar.xz .

For additional details on the capture command, refer to capture.

7.4.1.2. Identifying Issues from LEDs

LEDs offer quick visual diagnostics, using color and flashing patterns to indicate power, network, drive activity, and hardware errors, enabling rapid troubleshooting and reducing downtime.

Refer to the following sections for the location and meaning of each product/component LED.
