Active Memory
Active Memory is an IBM feature that improves the reliability of memory through
hot-swap memory, memory mirroring, memory scrubbing, and the Memory
ProteXion feature.
Memory scrubbing and Memory ProteXion
Memory scrubbing tests the memory at regular intervals to detect and report
recoverable memory ECC errors before they can cause server outages.
If the recoverable ECC error rate exceeds the system-defined threshold, the
Memory ProteXion feature replaces the failing bit positions, maintaining reliable
operation. If the recoverable ECC error rate exceeds the threshold again, light path
diagnostics LEDs are lit to indicate the failing DIMM.
You do not have to enable memory mirroring to use memory scrubbing and the
Memory ProteXion feature.
Memory mirroring
Memory mirroring stores data in memory port 1 and memory port 2 simultaneously.
To support memory mirroring, you must install identical dual inline memory modules
(DIMMs) in memory port 1 and memory port 2. For more information, see the
section about installing memory modules in the Option Installation Guide on the IBM
xSeries Documentation CD.
To enable memory mirroring through the Configuration/Setup Utility program, select
Advanced Setup from the main menu, and select Memory Configuration. For
more information about using the Configuration/Setup Utility program, see
Chapter 2, “Configuring the server,” on page 11.
Hot-swap memory
You can replace a failed DIMM while the server is turned on, provided that you
have enabled memory mirroring and that you have installed all DIMMs in the
sequence to support memory mirroring.
If a problem with a DIMM is detected, light path diagnostics LEDs are lit to indicate
the failing DIMM. When this occurs, identify the defective DIMM, and then remove
and replace the DIMM. For more information, see the information about installing
memory modules in the Option Installation Guide on the IBM xSeries
Documentation CD.

Setting up the Remote Supervisor Adapter
This section describes the Remote Supervisor Adapter features and its
prerequisites. It also explains how to cable and configure the adapter for use on an
Advanced System Management (ASM) network so that you can manage the server
from a remote location. For more detailed information, see the Remote Supervisor
Adapter User’s Guide on the IBM xSeries Documentation CD.
Attention: After you install your operating systems and fully configure your server,
be sure to make a backup copy of the nonvolatile EFI variables stored in NVRAM
on the Remote Supervisor Adapter. In the unlikely event that you need to remove or
replace the Remote Supervisor Adapter or clear NVRAM, you can use the backup
copy to restore the variables. See “Backing up and restoring the nonvolatile
variables” in the Option Installation Guide on the IBM xSeries Documentation CD
for more information.
