Hypervisor problems

The hypervisor provides error diagnostics with associated error codes and fault isolation procedures for troubleshooting.

When the hypervisor error analysis determines a specific fault, the hypervisor logs an error code that identifies a failing component. When the analysis is not definitive, the hypervisor logs one or more isolation procedures for you to run to identify and correct the problem.

Table 1 describes the isolation procedures.

Table 1. Hypervisor isolation procedures
  • Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved.
  • See Parts listing, type 7891 to determine which components are CRUs and which components are FRUs.
  • If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician.
Isolation Procedure Code Symptom Action
LPARCFG Symbolic CRU There is a configuration problem with the system or a logical partition.
  1. Perform the procedure associated with the SRC code that is called out after the LPARCFG call.
  2. Check processor and memory allocations of the system or the partitions.

    Verify that there are enough functioning processor and memory resources in the system for all of the partitions. Processor or memory resources that failed or were Garded during system IPL could cause the IPL problem in the partition.

  3. Check the bus and I/O adapter allocations for the partition.

    Verify that the partition has load source and console I/O resources.

  4. Check the IPL mode of the system or failing partition.

MEMDIMM Symbolic CRU The failing component is one of the memory DIMMs.
  1. Replace the failing CRU:
    DIMM 1 or 17 (Px-C1)
    P1-C1 is memory module 1;
    P2-C1 is memory module 17.
    DIMM 2 or 18 (Px-C2)
    P1-C2 is memory module 2;
    P2-C2 is memory module 18.
    DIMM 3 or 19 (Px-C3)
    P1-C3 is memory module 3;
    P2-C3 is memory module 19.
    DIMM 4 or 20 (Px-C4)
    P1-C4 is memory module 4;
    P2-C4 is memory module 20.

    P2-C8 is memory module 24.
    DIMM 9 or 25 (Px-C9)
    P1-C9 is memory module 9;
    P2-C9 is memory module 25.
  2. See Removing a memory module for location information and the removal procedure.
  3. Install new memory DIMMs, as described in Installing a memory module.

    DIMM 10 or 26 (Px-C10)
    P1-C10 is memory module 10;
    P2-C10 is memory module 26.
    DIMM 11 or 27 (Px-C11)
    P1-C11 is memory module 11;
    P2-C11 is memory module 27.
    DIMM 12 or 28 (Px-C12)

  2. See Removing a memory module for location information and the removal procedure.
  3. Install new memory DIMMs, as described in Installing a memory module.

See Supported DIMMs for more information.

NEXTLVL Symbolic CRU Contact IBM Support.
PIOCARD Symbolic CRU The hardware that controls PCI adapters and PCI card slots detected an error. The direct select address (DSA) portion of the system reference code (SRC) identifies the location code of the failing component.
  1. Collect the error log information.
  2. Get the DSA, which is word 7 of the associated B700xxxx SRC.
  3. Use the hexadecimal value of the DSA to determine the location code of the failing CRU.
  4. Reseat the device that you just installed.
  5. Replace the device that you just installed.
