Failure Scenarios
The UCS firmware upgrade process may fail for multiple reasons. The following are some of the most common reasons:
-
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.
-
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.
-
Unsupported Hardware - The upgrade fails, if the new firmware does not support some of the components.
-
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.
-
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. |
