Normally when a DIMM exceeds the threshold of correctable errors (CEs), the system maps it out, which disables it until it can be replaced.
Setting the DIMM CE Map Out policy allows you to prevent the system from mapping out DIMMs that exceed the CE threshold. This feature is available with Oracle ILOM 3.2.6 or later.
When DIMM CE Mapout is enabled, DIMMs that exceed the CE threshold are mapped out (disabled). This is the default.
When DIMM CE Mapout is disabled, DIMMs that exceed the CE threshold are not mapped out.
To enable or disable the DIMM CE Mapout policy:
From the Oracle ILOM web interface, navigate to System Management > Policy and use the drop-down list to enable or disable DIMM CE fault DIMM map out.
From the Oracle ILOM command-line interface (CLI), enter:
set /SP/policy DIMM_CE_MAP_OUT=[enabled/disabled]
