Hot-Upgrading Memory

For the hot-upgrade feature to work on the ProLiant DL760 G2 server, the operating
system must have driver support. Refer to "Installing HP Drivers and Utilities," in
Chapter 8 for details on installing HP software. HP recommends having all DIMMs
that will replace existing DIMMs available before beginning this upgrade procedure.
An upgrade is replacing smaller size DIMMs with larger size DIMMs.
CAUTION: A redundant memory configuration is required when performing Hot Plug
RAID Memory functions.

IMPORTANT: You cannot perform a hot-upgrade of memory if only four memory cartridges
are installed. The system must have a redundant memory configuration (five cartridges online
and error free) before the hot-upgrade feature will function.
5-20
If all five memory cartridges are online and error free, any memory cartridge can
be removed.
If one of the five memory cartridges requires attention, only that memory
cartridge can be removed.
If two or more memory cartridges require attention and are online (cartridge
power LED is illuminated), no cartridge can be removed while the system is
online. An audible alarm will sound if any cartridge is unlocked.
