Agent information 27
• Mirroring—This system is configured for Mirrored Memory Protection. All memory banks are duplicated in
Mirrored Memory, as opposed to only one for Online Spare Memory. If enough ECC errors occur, the
spare memory is activated and the memory experiencing the errors is disabled.
• RAID-XOR—This system is configured for Advanced Memory Protection using the XOR engine.
• Advanced ECC—This system is configured for Advanced Memory Protection using the AdvancedEcc engine.
• LockStep—This system is configured for Advanced Memory Protection using the LockStep engine.
Memory Summary
This section displays the information about the memory board or riser detail information.
• Condition—Displays the current condition of the Advanced Memory Protection subsystem. The following states
are supported:
• Other—The system does not support fault tolerant memory or the Management Agent cannot determine the
state.
• Ok—This system is operating normally.
• Degraded—The Advanced Memory Protection sub-system has been engaged. Schedule server down time to
replace the deactivated memory.
• Location—The Slot/CPU number in which the memory board or cartridge or riser is installed.
• System Board—There is no separate memory board slot, all DIMMs are installed on system board itself.
• Board Number—There is memory board slot available, all DIMMs are installed on the memory board.
• CPU Number—This displays the CPU number to which the memory DIMMs are installed.
• Riser Number—This displays the riser number to which the memory DIMMs are installed.
• Status—This provides the current status of the Advanced Memory Protection memory board or cartridge or riser.
The following status values are supported:
• Unknown—The value is unsupported or could not be determined.
• OK—The board or cartridge is configured and operating correctly.
• Correctable Memory Error—The board or cartridge has at least one DIMM ECC error.
• Unlock Error—The board or cartridge is unlocked when it should not be. Be sure that the board of cartridge
is locked.
• Configuration Error—The board or cartridge has a bad memory configuration. Be sure that all memory
modules are of the correct type, speed, latency, etc.
• Bus Error—The board or cartridge has a memory bus error. Please insure all memory modules are of the
correct type, speed, latency, etc. Be sure that the cartridge is inserted properly.
• Power Error—The board or cartridge has power error. Please insure all memory modules are of the correct
type, speed, latency, etc. Also insure the cartridge is inserted properly.
• Advanced ECC—The board or cartridge is configured for advanced ECC mode.
• Online Spare—The board or cartridge is configured for Online Spare mode.
• Mirrored—The board or cartridge is configured for mirrored mode.
• Uncorrectable Memory Error—The board or cartridge has a mirrored/RAID DIMM error.
• Memory RAID—The board or cartridge is configured for memory RAID mode
• LockStep—The board or cartridge is configured for LockStep mode.
• Uncorrectable LockStep Memory Error—The board or cartridge has a LockStep DIMM error.
• Present—This value specifies existence of the board or cartridge or riser in the Slot/CPU number.
• Locked—This value specifies whether the board or cartridge or riser is locked or not.
• Hot Plug—This value specifies whether the board or cartridge or riser is hot pluggable or not.
• Total Memory—This value specifies the size of memory for this board or cartridge or riser, including
memory seen by the OS and the memory used for spare, mirrored, RAID-XOR, or LockStep configurations.
• In Use by OS—This value specifies the size of memory for this board or cartridge or riser as seen by the
OS.
Memory Details
• Condition—Displays the condition of the memory module.
• Socket—Displays the socket number of memory module.
• Status—Displays the status of memory module whether in use or not.
• Type—Displays the type of memory installed.
