On single-processor systems, the show /System/memory command issued from the Oracle Integrated Lights Out Manager (ILOM) command-line interface (CLI) will incorrectly return max DIMMs = 16, when the maximum number of supported DIMMs on a single-processor system is 8.
Additionally, if a DIMM is mistakenly installed in a socket associated with the processor 1 (P1) socket, the following Oracle ILOM CLI commands will identify the misconfiguration by showing the DIMM associated with P1, even though P1 is not actually present in the system. Note, however, that the DIMM will not be usable by the system.
-> show /System/Memory/DIMMs
-> show /System/Memory/DIMMs/DIMM_n, where n can be any number from 8 through 15
-> show /SP/powermgmt/powerconf/memory
-> show /SP/powermgmt/powerconf/memory/MB_P1_D0
For the Oracle ILOM web interface, the System Information > Summary screen and the System Information > Memory screen incorrectly show the maximum number of supported DIMMs as 16, when the maximum number of supported DIMMs on a single-processor system is 8.
Affected hardware and software:
Single-processor Sun Server X3-2L systems
