When an internal hardware sensor alert is received indicating a 'Bad' power supply status, no detail is included which indicates which characteristic of the power supply's state is resulting in a 'Bad' overall status for the power supply. In this scenario, the message logged at default logging level contains information similar to the following: ... crit chmand[...]: 012a0013:2: Blade 0 hardware sensor critical alarm: Power Supply 2 GPIO status(SPAFFIV03G): Bad
Unable to diagnose cause of 'Bad' power supply status at default logging level to determine whether the probable cause is due to a power supply hardware fault or a possible external power source issue.
BIG-IP 2000-/4000-/5000-/7000-/10000-series appliances or VIPRION B2100-/B2200-series blades, in which one or more installed power supplies triggers an internal hardware sensor alert indicating a 'Bad' power supply status.
If power supply errors continue to be logged: 1. Set the libhal logging level to 'Debug': tmsh mod sys db log.libhal.level { value "Debug" } 2. Let the system run in this configuration for at least a few minutes to collect a number of chmand error logs, such as: ... debug chmand[...]: 012a0007:7: Power Supply 1 alert objid:0x16f local:1 status:0x3 pin:0x2 action:0xd ... debug chmand[...]: 012a0007:7: Received Sensor Alert: sensor id 0x16f slot 0xff ... debug chmand[...]: 012a0007:7: Power Supply 1 alert objid:0x16f local:1 status:0x1 pin:0x2 action:0x3. 3. Set the libhal logging level back to 'Notice': tmsh mod sys db log.libhal.level { value "Notice" } 4. Take a qkview or an archive of /var/log/ltm, and engage F5 Professional Services for further analysis.
When an internal hardware sensor alert is received indicating a 'Bad' power supply status, additional detail is now logged to help identify the cause of the 'Bad' overall status for the power supply.
