Changing Dual-Board Hot-Plug Memory Mirroring To Hot-Add Without Removing The Memory Board - HP ML570 - ProLiant - G2 Manual

If a DIMM configuration error is detected, the insertion is aborted and the LED(s)
next to the invalid DIMM(s) blink amber. You can then remove the board, fix the
DIMM configuration issue, and re-insert the board.
When a successful Hot-Add board insertion is complete, the Memory Status LED
turns solid green and all populated DIMM LEDs turn green. Unlike on a Hot-Mirror
board insertion, the Mirroring Status LED and the Board Removable LED remain
off.
Changing Dual-Board Hot-Plug Memory Mirroring to Hot-Add
Without Removing the Memory Board
In general, a system must be in Advanced ECC mode with only one memory board
installed in order to do a Hot-Add board insertion.
However, if you have a system configured for Dual-Board Hot-Plug Memory
Mirroring mode, you may decide not to use mirroring protection, and instead use
additional memory to improve performance. Without Hot-Add support, you would
have to power-cycle the system, run RBSU, select the Advanced Memory Protection
Mode as Advanced ECC, and boot back into the OS.
With Hot-Add support, you can perform the conversion from Dual-Board Memory
Mirroring mode to Advanced ECC mode with the OS making full use of the installed
memory without requiring any downtime.
To convert from Dual-Board Memory Mirroring Mode to Advanced ECC mode:
NOTE: It is not necessary to physically remove the board between steps 2 and 3. Simply
unlock and then lock the memory board. No unlatching or removal is required.
1. Run the Hot-Plug Memory Configuration Utility and select the board insertion
mode as Hot-Add. (The mode would have previously been Hot-Mirror since the
system is in Dual-Board Hot-Plug Memory Mirroring mode.)
2. Unlock memory board 2 (refer to Figure 6) and wait for the board to power
down. This usually takes no more than a second to complete. The Memory Status
LED will blink green until the board is without power. Once complete, the
Memory Status LED will be off.
