Failure Scenarios

The UCS firmware upgrade process may fail for multiple reasons. The following are some of the most common reasons:

  1. Hardware Issues - Faulty components, power, and cabling issues. It most often requires Return Merchandise Authorization (RMA), component re-seating or visual inspection of the hardware.

  2. Software Failure - This happens when certain components fail to apply the new software version. These components will skip the upgrade process and fall back to the previous or backup version.

  3. Unsupported Hardware - The upgrade fails, if the new firmware does not support some of the components.

  4. Software Misconfiguration - If the inappropriate firmware package is used or an attempt to upgrade to an incorrect or unsupported firmware version, the upgrade process fails.

  5. Timeout - If the upgrade takes more than 2 hours to complete, the sync process time outs and fails.

Note

The CIMC performs a list of prerequisites before proceeding with the firmware installation. When all the prerequisites are successful, the CIMC proceeds with the upgrade. There is no dry-run option available for the firmware upgrade.
