Resolving The Problem

Source

RETAIN tip:H194933

Symptom

Intelligent Platform Management Interface (IPMI) commands return condition code 0xC0 (NODE BUSY).

Affected configurations

The system may be any of the following IBM servers:

  • BladeCenter HS22, Type 7870, any model
  • System x3550 M2, Type 7946, any model
  • System x3550 M3, Type 4254, any model
  • System x3550 M3, Type 7944, any model
  • System x3650 M2, Type 7947, any model
  • System x3650 M3, Type 4255, any model
  • System x3650 M3, Type 7945, any model
  • iDataPlex dx360 M2 Server, Type 6380, any model
  • iDataPlex dx360 M2 Server, Type 7321, any model
  • iDataPlex dx360 M2 Server, Type 7323, any model

This tip is not option specific.

The system has the symptom described above.

Workaround

A script or IPMI application that receives completion code 0xC0 (Node Busy) should add a small delay and retry the command until it returns successful.

Additional Information

IPMI completion code 0xC0 (NODE BUSY) is returned because the Integrated Management Module (IMM) IPMI stack is either busy at the time the command was received or the IMM's IPMI stack is still in it's initialization phase and is not ready to handle commands yet.

Adding delays and retries to the scripts or applications that issue IPMI commands will allow the IMMs IPMI stack the opportunity to handle the commands and return successful completion codes.

There is no IMM firmware change planned to address this issue.
