Failure Impact
The impact of the firmware upgrade failure falls into the following three categories:
-
Non-Service Impacting - The server continues to work. This is the most common behavior. The reason for the failure are software misconfiguration, software failure or a failed prerequisites verification. In such a scenario, it’s recommended to troubleshoot the failure, fix the problem and upgrade firmware again either automatically (using the same sync process) or manually. A restart of the CIMC may also reset and unblock the issue.
-
Partially Service Impacting – The server continues to work with some performance, connectivity or stability issues. An unsupported hardware, incorrect firmware version, or an issue introduced with the new firmware may have caused this. In such a scenario, it’s recommended to perform a BUG scrub or validation to ensure that the OS version, drivers, firmware and hardware combination is officially supported by Cisco. You can perform the validation here:
-
Service Impacting – The server fails to boot or becomes inaccessible. If the firmware upgrade failure affects the CIMC access, then the server either must be sent for a RMA or physical access may be required. A hardware issue or a fatal error (needs further investigation by TAC team) might have caused this.
Note | When you are unable to identify the root cause, it is recommended to open a TAC
case and involve a UCS expert to help further troubleshoot the issue. |
