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:
-
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.
-
You can also use the CLI for the status of the last firmware for a node or multiple nodes in a cluster.
-
Based on the error, the root cause may have caused by either of the following reasons:
-
An incorrect UCS CIMC password was provided
-
An incorrect ISO was provided or the ISO was corrupt
-
The CIMC failed to download the ISO image. A firewall, security-group, or Cluster-Manager (based on the deployment) may have caused this issue
-
The CIMC failed to trigger, run, or validate the firmware upgrade
-
-
Access the CIMC server and verify the server console, SEL and alerts or issues for more details (if required).
-
Based on the sync logs and the CIMC data, identify the problem and its resolution. If required, perform a CIMC reboot
-
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
-
Open a TAC case and involve an UCS expert, if you are unable to find the root cause or resolve the issue.
