Symptoms

The frad daemon reports "Ignoring CRC error" or "TH Segment CRC is wrong on DIMM" errors into error log file in /var/opt/SUNWSMS/SMS1.2/adm/platform.

Every four hours, a record of powered-on components is written to the SEEPROM.
You may see hourly errors describing "Ignoring CRC error on DIMM with known bad CRC on DIMM" or "TH Segment CRC is wrong on DIMM".

If you have one of the older DIMMS (for example, part number 501-5401-01 DIMM) that has the older CRCs in the SEEPROM, you may see platform error messages similar to those shown below (in file /var/opt/SUNWSMS/SMS1.2/adm/platform):
