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.
