Management Module demand exceeds a single power module - IBM BladeCenter

Troubleshooting


Problem

Management Module power demand exceeds a single power module - IBM BladeCenter

Resolving The Problem

Source

RETAIN tip: H067860

Symptom

When a BladeCenter chassis fully configured with IBM BladeCenter HS20 blades, a power policy setting "Redundant with
performance impact.", and all blades are powered on, the following message appears:

"Demand exceeds a single power module, throttling can occur."

This message will appear in the Management Module Event Log, System Status Summary and main Fuel Gauge Power Domain page.

Affected configurations

The system may be any of the following IBM Systems:

  • BladeCenter, type 8677, any model
  • BladeCenter, type 8843, any model

The 73E Firmware for the BladeCenter Management Module is affected.

Solution

None. The BladeCenter Management Module is working as designed.

Note: These messages are only warnings of what could potentially happen in the unlikely event of an actual power supply failure.

Additional information

This message occurs when the overall demand has exceeded the requirements for a single power supply. Therefore, in a redundant configuration with a performance impact policy, throttling would only occur in the event of a power fault on one of the power supplies.
