Table 35. Hypervisor isolation procedures (continued)
v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v See Chapter 3, "Parts listing, type 7891," on page 225 to determine which components are CRUs and which
components are FRUs.
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.
Isolation
Symptom
Procedure Code
The failing
MEMDIMM
Symbolic CRU
component is one of
the memory DIMMs.
NEXTLVL
Contact IBM Support.
Symbolic CRU
PIOCARD
The hardware that
Symbolic CRU
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.

Action
1. Replace the failing CRU:
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)
P1-C12 is memory module 12;
P2-C12 is memory module 28.
DIMM 13 or 29 (Px-C13)
P1-C13 is memory module 13;
P2-C13 is memory module 29.
DIMM 14 or 30 (Px-C14)
P1-C14 is memory module 14;
P2-C14 is memory module 30.
DIMM 15 or 31 (Px-C15)
P1-C15 is memory module 15;
P2-C15 is memory module 31.
DIMM 16 or 32 (Px-C16)
P1-C16 is memory module 16;
P2-C16 is memory module 32.
2. See "Removing a memory module" on page 249 for location
information and the removal procedure.
3. Install new memory DIMMs, as described in "Installing a memory
module" on page 251.
See "Supported DIMMs" on page 4 for more information.
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.
v If the value is 05120010, the location code is P1-C19 or P2-C19.
v If the value is xxxx 0100, the location code is P1-C20 or P2-C20.
4. Reseat the device that you just installed.
5. Replace the device that you just installed.
