Measures reported by EqlControllerTest

The Dell EqualLogic PS Series supports dual controllers, which are redundant and hot-swappable. The controller module features dual-core 64-bit processors with a HyperTransport™ I/O bus and twin 64-bit double data rate (DDR) channels. Each control module is equipped with 1GB of battery-backed DRAM.

To ensure that the controllers are functioning properly, the temperature of their processors and the strength of their battery backups should be periodically checked so that, abnormalities can be quickly detected and fixed.

This test auto-discovers the available controllers in the PS Series array, and reports the above for each controller. In addition, this test also reveals which of the controllers is the primary controller in the redundant setup, and which is the secondary.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Battery_status Indicates the status of the battery present in this controller.   This measure reports the state of the battery present in this controller as follows:
  • Ok
  • Failed
  • Good Battery
  • Low Voltage
  • Low Voltage Charging
  • Missing Battery

The numeric values that correspond to the above-mentioned states are as follows:

State Numeric Value
Ok 1
Failed 2
Good Battery 3
Low Voltage 4
Low Voltage Charging 5
Missing Battery 6

Note:

By default, this measure reports the above-mentioned states while indicating the state of the battery present in this controller. However, the graph of this measure will be represented using the corresponding numeric equivalents of the states as mentioned in the table above.
Total_uptime Indicates the time that elapsed since the controller was last booted. Secs By carefully observing the changes in the measure, you can promptly detect unexpected breaks in the availability of the controller.
Processor_temperature Indicates the current temperature of the processor supported by this controller. Celcius Ideally, this value should be low.
Chipset_temperature Indicates the current temperature of the chipset supported by this controller. Celcius A low value is desired for this measure.
Controller_status Indicates whether the controller is the primary controller or the secondary.   This measure reports the value Primary or Secondary depending upon whether the controller is the primary controller or the secondary controller in the redundant setup.

The numeric values that correspond to the above-mentioned states are as follows:

State Numeric Value
Primary 1
Secondary 2

Note:

By default, this measure reports the above-mentioned States while indicating the status of the controller. However, the graph of this measure will be represent states using the corresponding numeric equivalents - 1 or 2 only.
