MAP 0260: System hangs during resource configuration

Purpose of this MAP

This MAP handles problems when the system unit hangs while configuring a resource.

• Step 0260-1

  The last three or four digits of the SRN following the dash (-) match a failing function code number.

  Look at the System parts and find the failing function code that matches the last three or four digits of your SRN, following the dash. Record the FRU part number and description (use the first FRU part listed when multiple FRUs are listed).

  The physical location code, AIX® location code, or device name is displayed on the operator panel.

  Do you have either a physical location code or AIX location code displayed?

  No

  Go to Step 0260-4.

  Yes

  Go to Step 0260-2.

• Step 0260-2
  Are there any FRUs attached to the device described by the physical location code or AIX location code?

  No

  Go to Step 0260-6.

  Yes

  Go to Step 0260-3.

• Step 0260-3

  Remove this kind of FRU attached to the device described in the location code one at a time. Note whether the system still hangs after each device is removed. Repeat this step until you no longer get a hang, or all attached FRUS have been removed from the adapter or device.

  Has the symptom changed?

  No

  Go to Step 0260-4.

  Yes

  Use the location code of the attached device that you removed when the symptom changed, and go to Step 0260-6.

• Step 0260-4
  Does your system unit contain only one of this kind of FRU?

  No

  Go to Step 0260-5.

  Yes

  Go to Step 0260-6.

• Step 0260-5

  One of the FRUs of this kind is defective.

  Remove this kind of FRU one at a time. Test the system unit after each FRU is removed. Stop when the test completes successfully or when you have removed all of the FRUs of this kind.

  Were you able to identify a failing FRU?

  No

  Go to PFW1540: Problem isolation procedures.

  Yes

  Go to Step 0260-6.
