OBP hides all memory installed on a system board by setting this environment variable.
# eeprom no-mem-sb-cX=Y
# eeprom no-mem-sb="XY"
# eeprom no-mem-sb="XY-N"
where X is the cabinet number , Y is the slot number within the cabinet and N is logical number in the system board. The syntax is the same as Kernel memory allocation option.
The specified boards must be listed on no-obp-sb-cX property as well. Otherwise, memory nullification doesn't work appropriately.
When a specified system board is attached by DR operation, the following message might appear but there is no harm to the DR operation. You can ignore it and proceed with the operation.
sfdr:sfdr_get_memlist: nodeid (0x0) is not memory node
If the board is configured as a memory less board, memory detach operation always succeeds. You do not need to consider the conditions mentioned in "2.1.3.3 DR Detach".
