IBM System x3650 Type 7979 Problem Determination And Service Manual page 49

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 7979 and 1914 server," on page 79 to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.
Error code Description
178x Fixed disk error.
Note: x is the drive that has the error
1800 Unavailable PCI hardware interrupt.
1801 An adapter has requested memory
resources that are not available
Note: The server can allocate only 128 KB
of option load space (option ROM space);
error code 1801 occurs if the load space
required by an option ROM when loading
exceeds the available (remaining) load
space. Changing the option load order can
cause an option ROM that requires more
load space to load sooner, when more load
space is available; the other option ROMs
might still fit in the remaining load space.
With some options, some or all of the load
space used is released after the ROM code
loads and initializes the option.
Action
1. Run the hard disk drive diagnostics tests on drive
x.
2. Reseat the following components:
a. Hard disk drive
b. Cable from the system board to the backplane
3. Replace the following components one at a time,
in the order shown, restarting the server each
time:
a. Hard disk drive
b. Cable from the system board to the backplane
c. Hard disk drive backplane
d. (Trained service technician only) System
board
1. Run the Configuration/Setup Utility program and
adjust the adapter settings.
2. Remove each adapter one at a time, restarting
the server each time, until the problem is isolated.
1. If possible, rearrange the order of the adapters in
the PCI slots, to change the load order of the
option ROM code.
2. Run the Configuration/Setup Utility program,
select Startup Options, and change the boot
sequence, to change the load order of the option
ROM code.
3. Run the Configuration/Setup Utility program and
disable some other resources, if their functions
are not being used, to make more space
available.
v Select Startup Options then Planar Ethernet
(PXE/DHCP) to disable the onboard Ethernet
controller option ROM.
v Select Advanced Functions, then PCI Bus
Control, then PCI ROM Control Execution to
disable the option ROM of adapters in the PCI
slots.
v Select Devices and I/O Ports to disable any of
the onboard devices.
4. If the problem remains, replace the following
components one at a time, in the order shown,
restarting the server each time:
a. Each adapter
b. (Trained service technician only) System
board
