DIMM Configuration Errors
When the server boots, system firmware checks the memory configuration against the rules
described in “Memory Riser and DIMM Configuration” on page 89 . Any violations of
these rules produce a general error message:
Please refer to the service documentation for supported memory
configurations.
In some cases, the server boots a degraded state:
WARNING: Running with a nonstandard DIMM configuration. Refer to service document for
details.
In other cases, the configuration error is fatal:
Fatal configuration error - forcing power-down
In addition to these general memory configuration errors, one or more rule-specific messages is
displayed, indicating the type of configuration error detected. To identify the DIMMs affected,
use the
fmadm faulty
command as described in “Checking for Faults” on page 27 .
