Hypervisor Problems - IBM PS703 Service Manual

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 35 describes the isolation procedures.
Table 35. 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 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.

Action
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.
