Not reading device on system management (I2C) bus [arg1]. Fan module [arg2] communication is offline.
The Chassis Management Module (CMM) is not able to communicate with the specified fan module. If there is an error in a fan logic module, the CMM cannot monitor the associated fan modules or detect their presence, and the fan modules on that side of the chassis will speed up. Solve fan logic module issues before you address fan-module issues.
