POWER Hypervisor (PHYP) problems
The POWER Hypervisor (PHYP) provides error diagnostics with associated error codes and fault
isolation procedures for troubleshooting.
When the POWER7 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 33 describes the isolation procedures.
Table 33. POWER Hypervisor isolation procedures
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 8406,” on page 229 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.

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.
