v There is a system reference code or message on the
partition's console.
v The customer reports reduced function in the partition.
v There is a partition performance problem.
v There are failing, missing, or inoperable resources.

Table 5. Problem with a guest partition
Note: These are reported from the operating system (other than OS/400
partition or reported from the hosting partition of a guest partition. See the definitions for guest
partition and hosting partition in the Terminology page.
Symptom
Is the problem appearing from a guest operating system?
To determine if the system has guest partitions, see
Determine if the system has guest partitions.
Is the problem appearing in the hosting partition of a
guest partition?
To determine if a partition is a guest partition, see
Determine if the system has guest partitions or ask the
customer if the problem is appearing in the hosting
partition for a guest partition.
Table 6. Time-of-day problem
Symptom
System clock loses or gains more than 1 sec/day when
the system is connected to utility power.
System clock loses or gains more than 1 sec/day when
the system is disconnected from utility power.
Table 7. There is an obvious physical symptom
Symptom
A light or display on the system unit control panel or on a
FC 507x system unit expansion, a FC 508x storage
expansion unit, a FC 506x PCI expansion unit control
panel, or (in Models 820, 830, SB2, and SB3 only, a FC
9251 base I/O tower is not working correctly.
A light or display on the control panel of the FC 504x
system unit expansion is not working correctly.
One or more of the following was reported:
v Noise
v Smoke
v Odor
What you should do:
From the partition's console search the partition's Service
Action Log. Go to "Use the service action log" on page 7.
Note: On most systems with multiple partitions, it is
common to have one or more "Missing or Non-reporting"
system bus resource's under Hardware Service Manager.

See iSeries Service Functions
Go to "TU-PIP6" on page 234.
What you should do:
If there are Service Action Log (SAL) entries in the
Primary partition or the hosting partition, work these
problems first.
To determine the hosting partition for a guest partition see
Determine if the system has guest partitions.
If there are no SAL entries in the Primary partition and no
SAL entries in the Hosting partition, then, contact your
next level of support.
What you should do:
Replace the service processor. See the symbolic FRU
"SVCPROC" on page 464.
Replace the time-of-day battery on the service processor.
For service processor location information, see Locations
and addresses for the model on which you are working.
The associated table will direct you to the remove and
replace procedure.
What you should do:
Perform "SPCN PIP20" on page 222.
Perform SPCN-PIP4 in the SY44-4934-00, FC 504x
Problem Analysis and Repair and Parts information.
Go to System safety inspection.
