Messages displayed on the VIPRION chassis LCD display always reference the blade number of the Primary blade in the chassis at the time that the message was issued. The slot number where the blade-specific condition is not included in message in the LCD display. In the case of CPU status alerts, where the CPU temperature is too high or the CPU fan speed is too low, the identification of the blade is not included in the console output or log messages produced by the system_check utility.


It may not be possible to accurately determine which blade has actually experienced a blade-specific condition reported on the chassis LCD display.


Affects: VIPRION B4100 (PB100), B4200 (PB200) and B4300-series blades in VIPRION C4400, C4480 and C4800 chassis. VIPRION B2100, B2150 and B2250 blades in VIPRION C2400 and C2200 chassis with external LCD displays attached.


Use one of the following commands to examine the CPU measurements to determine which CPU on which blade is experiencing excessive temperature and/or slow fan speed: 1. tmsh show sys hardware 2. tmctl cpu_status_stat

Fix Information

The system_check utility now logs the blade number as part of CPU status alerts to the system console and log messages. Such detail is not made available on the LCD display.
