IBM @Server pSeries 630 6C4, Service Manual

Page: 398 / 651

The error status of each processor is indicated by AB, where B indicates the number of errors and A
indicates the type of error according to the following:
1. Bring-up failure
2. Run-time non-recoverable failure
3. Run-time recoverable failure
4. Group integrity failure
5. Non-repeat-gardable error. The resource may be reconfigured on the next boot.
A status of 00 indicates that the CPU has not had any errors logged against it by the service processor.
To enable or disable CPU repeat gard, use menu option 77. CPU repeat gard is enabled by default.
If CPU repeat gard is disabled, processors that are in the
″
deconfigured by system
″
state will be
reconfigured. These reconfigured processors are then tested during the boot process, and if they pass,
they remain online. If they fail the boot testing, they are deconfigured even though CPU repeat gard is
disabled.
The failure history of each CPU is retained. If a processor with a history of failures is brought back
online by disabling repeat gard, it remains online if it passes testing during the boot process. However, if
repeat gard is enabled, the processor is taken offline again because of its history of failures.
Notes:
1. The processor numbering scheme used by the service processor is different from the numbering
scheme used by the operating system. Consult the operating system documentation before
configuring or deconfiguring a processor to ensure that the correct processor is selected.
2. To determine the number of processors available to AIX, run the following command on the AIX
command line: bindprocessor -q
3. The number of processor available to Linux can be determined by issuing the following command on
the Linux command line:
cat /proc/cpuinfo | grep POWER
v Memory Configuration/Deconfiguration Menu
Enable/Disable Memory Repeat Gard
Memory repeat gard will automatically deconfigure a quad of memory during a system boot if a
memory DIMM has failed BIST (power-on self-test), caused a machine check or check stop, or
has reached a threshold of recoverable errors. The quad will remain deconfigured until repeat
gard is disabled or the memory is replaced.
The default is enabled.
For more information, see “Configuring and Deconfiguring Processors or Memory” on page 398.
Runtime Recoverable Error Repeat Gard
The runtime recoverable error repeat gard flag controls the deallocation of the memory if a
recoverable error occurs during runtime. If a recoverable memory error occurs, and runtime
recoverable error repeat gard is disabled, the system will continue running with no change in
the memory configuration. If a recoverable memory error occurs, and runtime recoverable error
repeat gard is enabled, the memory quad in which the error occurred will be garded out (taken
offline).
The default is disabled.
