Troubleshooting

If one or multiple servers fail to upgrade the firmware, you must follow these steps to isolate and identify the origin or root cause of the issue:

  1. Verify the output of the sync process. It contains the high-level details of the root cause and exact step where of the firmware upgrade failed.

  2. You can also use the CLI for the status of the last firmware for a node or multiple nodes in a cluster.

  3. Based on the error, the root cause may have caused by either of the following reasons:

    1. An incorrect UCS CIMC password was provided

    2. An incorrect ISO was provided or the ISO was corrupt

    3. The CIMC failed to download the ISO image. A firewall, security-group, or Cluster-Manager (based on the deployment) may have caused this issue

    4. The CIMC failed to trigger, run, or validate the firmware upgrade

  4. Access the CIMC server and verify the server console, SEL and alerts or issues for more details (if required).

  5. Based on the sync logs and the CIMC data, identify the problem and its resolution. If required, perform a CIMC reboot

  6. If you can identify the error and resolve the issue, re-run the upgrade either automatically (through sync process) or manually. You must have the ISO image to perform this operation

  7. Open a TAC case and involve an UCS expert, if you are unable to find the root cause or resolve the issue.
