USB error handling 5 If the firmware download fails in a director or enterprise-class platform, the CPs may end up with different versions of firmware and are unable to achieve HA synchronization. In such cases, issue the firmwareDownload -s command on the standby CP; the single mode (-s) option allows you to upgrade the firmware on the standby CP to match the firmware version running on the active CP. Then reissue the firmwareDownload command to download the desired firmware version to both CPs. For example, if CP0 is running v7.0.0 on the primary and secondary partitions, and CP1 is running v7.1.0 on the primary and secondary partitions, then synchronize them by issuing the firmwareDownload command. NOTE Some of the messages include error codes (as shown in the following example). These error codes are for internal use only and you can disregard them. Port configuration with EX ports enabled along with trunking for port(s) 63, use the portCfgEXPort, portCfgVEXPort, and portCfgTrunkPort commands to remedy this. Verify blade is ENABLED. (error 3) Gathering additional information You should follow these best practices for firmware download before you start the procedure: • Keep all session logs. • Enter the supportSave or the supportShow command before and after entering the firmwareDownload command. • If a problem persists, package together all of the information (the Telnet session logs and serial console logs, output from the supportSave command) for your switch support provider. Make sure you identify what information was gathered before and after issuing the firmwareDownload command.
