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 the NAS operating system, run the following
command on the command line: bindprocessor -q

Enable/Disable Memory Repeat Gard
Memory repeat gard will automatically deconfigure a quad of memory during a system boot if a
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 287.
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 taken offline.
The default is disabled.
