Measures reported by IBMChassFanPckTest
The IBM BladeCenter Chassis comes with four hot-swappable fan modules (fan packs). The fan modules are designed to provide cooling airflow to the chassis and other modules. Each fan module contains two fans. These fan modules ensure that the temperature of the target chassis is within a permissible level. If any of the fan modules are not working properly or become unavailable suddenly, then the temperature of the chassis cannot be automatically regulated. This may cause the internal temperature of the chassis to rise uncontrollably, resulting in considerable damage to the modules in the chassis. This is why, the availability of the fan modules should be verified time and again, and abnormalities (if any) should be escalated to administrators. This is exactly what the Chassis Fanpack test does!
This test auto-discovers the fan modules of the target chassis and reports the availability and current status of each fan module. In addition, the test also checks the number of fans in each fan module and the average speed of the fan modules. This way, it turns the spotlight on those fan modules that are not operating within the permissible range.
Outputs of the test : One set of results for each fan module in the BladeCenter chassis being monitored.
Descriptor of the test : Fan Module
