Abstract This guide provides reference information for Hot-Add Memory functionality for the HP ProLiant DL580 Generation 2 and HP ProLiant ML570 Generation 2 servers. Audience Assumptions This guide is for the person who installs, administers, and troubleshoots servers. HP assumes you are qualified in the servicing of server equipment and trained in recognizing hazards in products with hazardous energy levels. -
Page 5: Hot-Add Memory Installation On Hp Proliant Dl580 Generation 2 And Ml570 Generation 2 Servers
Hot-Add Memory Installation on HP ProLiant DL580 Generation 2 and ML570 Generation 2 Servers Overview Hot-Add functionality allows you to upgrade the amount of memory in the server without powering down or rebooting the server. This functionality eliminates server downtime and service interruption when performing a memory upgrade. Hot-Add functionality is a feature developed for the HP ProLiant DL580 Generation 2 and HP ProLiant ML570 Generation 2 servers. -
Page 6: Description
Description Hot-Add Functionality Hot-Add functionality is made possible by a combination of a Hot-Add aware OS (currently Windows Server 2003 Enterprise Edition), system BIOS, and the Hot-Add memory driver (the Advanced System Management Controller Driver provides this function on these platforms). In addition, the hardware platform needs to support hot-pluggable memory modules or cards. -
Page 7: Requirements For A Hot-Add Functionality Upgrade
When the board insertion is complete, the OS registers the additional memory and it is then available for use by the OS and applications. The server can support up to 32 GB of memory, and a Hot-Add board insertion can upgrade to the total memory capacity, assuming all DIMM configuration requirements are met. -
Page 8: Dimm Configuration Requirements For Hot-Add
Hot-Add is NOT supported in the following modes: • Advanced ECC when both memory boards are installed. In this case, no empty memory board slots are available for additional memory to be inserted. • Online Spare Mode • Single-Board Mirroring Mode IMPORTANT: If you attempt a Hot-Add board insertion while in Online Spare mode or Single- Board Mirroring Mode, all LEDs on the memory board flash amber and the system internal speaker emits a warning tone as soon as the board is latched, before closing the locking... -
Page 9: Configuring The Servers For Hot-Add Functionality
Configuring the Servers for Hot-Add Functionality Hot-Add memory functionality can be configured using either the Hot-Plug Memory Configuration Utility or RBSU. Hot-Plug Memory Configuration Utility The Hot-Plug Memory Configuration Utility is a Windows Server 2003 Enterprise Edition application that allows you to select Hot-Add or Hot-Mirror. This allows the server to be configured for the desired board insertion mode at runtime without rebooting the server. -

RBSU Options The board insertion mode is also configurable in RBSU. The menu for selecting the board insertion mode in RBSU (refer to Figures 2 through 5) can be accessed by selecting the System Options menu, then the Hot-Plug Board Insertion Mode menu. - Page 11 Figure 3: Changing RBSU Hot-Plug Board Insertion Mode Figure 4: RBSU Hot-Add warning (when in Dual-Board Hot-Plug Mirrored Memory mode) HP ProLiant DL580 Generation 2 and HP ProLiant ML570 Generation 2 Server Hot-Add Memory...

Page 12: Typical Hot-Add Board Insertion With An Empty Memory Slot
Figure 5: RBSU Dual-Board Hot-Plug Mirrored Memory warning (when in Hot-Add mode) Typical Hot-Add Board Insertion with an Empty Memory Slot A typical Hot-Add board insertion is very similar to a board insertion when performing a hot-plug event in Dual-Board Hot-Plug Memory Mirroring mode. The memory board is inserted and latched (refer to the documentation that shipped with the server). -
Page 13: Changing Dual-Board Hot-Plug Memory Mirroring To Hot-Add Without Removing The Memory Board
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. -

3. Lock the memory board. The Hot-Add board insertion starts. When complete, the OS will have use of all the memory previously reserved for mirroring functionality. Figure 6: Locking and unlocking the memory board (locked position shown) Additional Considerations When Upgrading to Hot-Add Functionality Test for Faulty DIMMs Before a Hot-Add Board Insertion HP strongly recommends that the DIMMs be validated before attempting a... - Page 15 If an application is already running, it may have already allocated and requested its memory. In this situation, the application would need to be restarted (or some other action taken) for it to begin taking advantage of the expanded memory. Other applications that continuously request additional memory usually can take advantage of the new memory without any user intervention.
