Cfg for specified reboot of H3C core switch

Use the boot boot-loader primary command to specify the software image for the next reboot, then execute a controlled reboot from system view.Steps to Configure a Specified Reboot
  1. Access the CLI and Enter System View Log in to the switch and enter system view using: system-view This allows you to configure system-wide settings, including boot parameters.
  2. Specify the Bootstrap Program Use the boot boot-loader primary command to set the desired application file for the next reboot. For example:
    • For the active SRPU: boot boot-loader primary flash:/S9500-CMW310-r1262.app
    • For a standby SRPU in slot 1: boot boot-loader primary slot1#flash:/S9500-CMW310-r1262.app Ensure the file exists in the CF card or root directory of the Flash memory; otherwise, the configuration will fail .
  3. Verify the Boot Configuration Use the display boot-loader command to confirm the primary and backup applications set for the next reboot: display boot-loader This will show the current primary and backup APP files for each board .
  4. Perform a Controlled Reboot To safely reboot the device without risking file system damage, use the following steps:
    • Navigate to the maintenance menu in the Web interface: Device > Maintenance > Reboot
    • Click Reboot Device and confirm by clicking Apply Avoid using a force reboot unless the system is unresponsive, as it bypasses software checks and may damage the file system .
  5. Post-Reboot Verification After the switch reboots, re-access the CLI or Web interface to ensure the device has booted the specified image and is functioning correctly.
Notes and Best Practices
  • Always ensure the specified APP file is compatible with your switch model and stored in the correct location.
  • For switches with dual SRPUs, configure both active and standby SRPUs if needed.
  • Avoid force reboot unless necessary; a controlled reboot preserves system integrity.
  • Backup the current configuration before performing a reboot to prevent data loss. By following these steps, you can safely configure an H3C core switch to reboot using a specified software image, ensuring controlled startup and system stability .
