Installation, Removal, And Replacement Procedures - HP ML570 - ProLiant - G2 Installation Manual

Installation, Removal, and Replacement Procedures

DIMM and memory board installation, removal, and replacement procedures can be
either hot-plug or non-hot-plug procedures, depending on how the server is
configured.
•
You cannot perform hot-plug procedures when the system is configured for:
— Advanced ECC memory
— Online spare memory
— Single-board mirrored memory
•
While you cannot currently hot-add DIMMs, hot-add capabilities will be
available in a future software release, enabling you to dynamically increase
system memory capacity while the system is running. For more information
about hot-add functionality, refer to the Advanced Memory Protection white
paper on the website:
www.compaq.com/products/servers/technology/memoryprotection.html
•
You cannot perform hot-add or hot-replace procedures when the system is
configured for advanced ECC (standard) memory.
•
You can perform a hot-replacement procedure when the server is configured for
hot-plug mirrored memory, enabling you to remove a memory board, remove a
failed or degraded DIMM, replace it with a new DIMM, and reinstall the memory
board, all without powering down the server or experiencing server downtime.
The replacement procedures in this section apply to both hot-plug and non-hot-plug
memory procedures, except as noted.
NOTE: Hot-add memory allows ranges of memory to be added to the server and made
available to the operating system and applications as part of the normal memory pool without
requiring a reboot of the server. This feature will only operate on servers that have the hot plug
mirroring capability enabled while using the Windows.NET and certain Unix server family
operating systems. When utilizing this capability, an equal amount of memory needs to be
added to maintain parity between the two memory boards while in mirrored memory mode.
