FixIT: IBM Power Error Code B150F22A

At CentricsIT, we are your IT experts. When any IT maintenance issue arises in your data center we are here to help. If there is an error code you can’t fix, let us assist you in our monthly FixIT column. This month, we’re discussing the IBM error: B150F22A.

Encountering this error is probable when connecting and powering on a 16-way, two-drawer, IBM 9116-561 server.

B150F22A There was not enough functional nodes found in the system to continue IPLing.
FixIT:

Check the error log through Advanced System Maintenance Interface (A.S.M.I)

  • First, choose the “System Service Aids “ option from the main menu by clicking the “+” sign.
  • Next, select the “Error/Event Logs” option from the drop down menu

Two associated error codes commonly logged are:

  1. 508FF44B—CEC Hardware Subsystem, Unrecoverable Error, SRC = B150F22A
  2. 508FF402—CEC Hardware Subsystem, Unrecoverable Error, SRC = B150F22A

Result:

Priority: Mandatory, replace all with this type as a unit

Procedure Number: FSPSP01

The service processor needs to be replaced. Start by verifying that either drawer has really be disconfigured.

  1. Select “System Configuration” from the left main menu options.
  2. Select the “Hardware Deconficguration” option.
  3. Select the “Processor Deconfiguration” option from the drop down.Processor Deconfig
  4. Selecting each processing unit will identify any deconfigured processors.

Despite the error code clearly pointing toward the service processor, both drawers appear to have all 16 processors set as configured. The description citing “not enough functional nodes” suggests the flex cables could be a potential cause.

Since the error relates to the service processor, focus on the rear flex cable feature code 1857. This feature comes in a variety of part numbers but the CCIN should always be 185D.

Always check all the pin connections to verify that none are bent. Bent pins are a definite issue, but swapping the cable has the same outcome in this scenario.

A basic reseating of the processor books and re-IPL of the system shows that all nodes appear as configured. The error code was a “ghost” and disappeared when the hardware phase of the configuration was reset. By reseating the CEC cage components, all 16 processors will appear as configured on the HMC screen for manageability.

If you wish to determine whether the SRC requires a service action or if it is mainly for tracking purposes, refer to (B1xx) Service processor firmware reference codes for instructions.
