DIMM Configuration Errors (System Console)

When the system boots, system firmware checks the memory configuration against the rules described in DIMM Population Rules (Except 1536-Gbyte Configurations). If any violations of these rules are detected, the following general error message is displayed.

Please refer to the service documentation for supported memory configurations.

In some cases, the server boots in a degraded state, and a message such as the following is displayed:

NOTICE:  /SYS/PM0/CMP1/CORE0/P0 is degraded

In other cases, the configuration error is fatal, and the following message is displayed:

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. The following table identifies and explains the various DIMM configuration error messages.


Note - The messages described in this table apply to SPARC T4-4 servers. The DIMM configuration requirements for other servers in the SPARC T4 series are different in some details, so some of their configuration error messages are also different.


DIMM Configuration Error Messages
Notes
Fatal configuration error - forcing power-down.
Ensure that DIMMs are installed in a supported configuration.

See DIMM Population Rules (Except 1536-Gbyte Configurations).

Ensure that DIMMs associated with each CMP are identical (identical capacity, identical DIMM classification).

See DIMM Rank Classification

See Increase Memory With Additional DIMMs.

See Increase Memory With Additional DIMMs (16-Gbyte Configurations).

Not all MCUs enabled.

 Unsupported Config.

Ensure that DIMMs are installed in a supported configuration.

See DIMM Population Rules (Except 1536-Gbyte Configurations).

Ensure that all processor modules and all DIMMs are installed and seated correctly.

See Install a Processor Module.

See Install a DIMM.

Invalid DIMM population.

    No DIMM is present in MCUn/BOBn

Install a DIMM with the appropriate characteristics in the slot specified in the message.

See Understanding DIMM Configurations.

Not all DIMMs have the same SDRAM capacity.
All DIMM components must have the same capacity — all 4 Gbyte, all 8 Gbyte, all 16 Gbyte, or all 32 Gbyte.1

Replace any DIMMs that do not match the desired capacity.

See Understanding DIMM Configurations.

Not all DIMMs have the same device width.
All DIMM components must have the same device width.

Replace any DIMMs that do not match the desired width.

See DIMM Rank Classification.

Not all DIMMs have the same number of ranks.
All DIMM components must have the same number of ranks.1 The supported rank arrangements are:
  • 2 ranks—4-Gbyte, 8-Gbyte, 16-Gbyte DIMMs

  • 4 ranks—16-Gbyte and 32-Gbyte DIMMs

Replace any DIMMs that do not match the desired rank number.

See DIMM Rank Classification.

Invalid DIMM population. DIMMs in the same position must be all present or absent.
Memory configurations must be populated in sets of 8 or 16 DIMMs for each CMP.

See Understanding DIMM Configurations.

Either add DIMM components to fill a partially populated set or remove DIMM components to empty a partial set.


Note - The DIMM slots labeled sets 1 and 2 in the figure must always be fully populated.


Invalid DIMM population. T4-4 only supports 1/2 or full memory configs.
Add or remove DIMM components to achieve one of the supported memory configurations.

See Understanding DIMM Configurations.

DIMM population across nodes is different.
If the processor modules in a server have different DIMM populations, add or remove DIMM components until they are equal.

See Understanding DIMM Configurations.

DRAM capacity of DIMMs is different across nodes.
If the processor modules in a server have different DRAM capacities, replace some DIMM components until all DRAM capacities are the same.

See Understanding DIMM Configurations

Device width of DIMM is different across nodes.
If the CMPs in a server have DIMMs with different device widths, replace some DIMM components until all DIMMs have the same device width.

See DIMM Rank Classification.

Number of ranks of DIMM is different across nodes.
If the CMPs in a server have DIMMs with different rank arrangements, replace some DIMM components until all rank numbers are the same.

See DIMM Rank Classification.

1Restriction does not apply to 1536-Gbyte configurations.
