The messages displayed constantly %PLATFORM_THERMAL-6-FRU_FAN_RECOVERY: Switch 1: System fan # recovered to normal status %PLATFORM_THERMAL-1-FRU_FAN_FAILURE: Switch 1: System fan # failed show environment fan Switch FAN Speed State --------------------------------------------------- 1 1 5160 OK 1 2 0 NOT PRESENT or FAULTY * Physically the FAN # works although it displayed the error messages * The temperature of the device is in normal parameters
* Must be running a fixed version for CSCvy10601 * FAN # reports a failure * FAN # shows a message that it recovered * Reload doesn't help, message comes back after a while
- Reload (Fix the issue temporarily) If reload does not clear condition then power cycle. The workaround is temporary.
