I2C bus Errors
The following sections cover troubleshooting i2C bus errors.
Possible Causes
i2C bus errors indicate defective hardware, and the specific item is listed in the
error message. Refer to the HP StorageWorks Diagnostic and System Error
Message Version 3.1.x/4.1.x Reference Guide for information specific to the error
that was received. Specifically, some CPT and Environmental Monitor (EM)
messages contain i2C-related information.
Troubleshooting the Hardware
If the i2C message does not indicate the specific hardware that may be failing,
begin debugging the hardware, as this is the most likely cause.
Check Fan Components

2. Enter fanshow at the command line.
3. Check the Fan status and speed output.
If any of the fan speeds display abnormal RPMs, replace the fan FRU.
Check the Switch Temperature
