SMART Support
SMART is a technology that monitors hard disk drives for signs of future disk failure and
generates an alert if such signs are detected. The firmware polls each physical disk in
the volume at regular intervals. If the firmware detects a SMART ASC/ASCQ code on a
physical disk in the IS volume, it processes the SMART data and stores it in nonvolatile
memory. The IS volume does not support SMART directly, since it is just a logical
representation of the physical disks in the volume.
Disk Write Caching
Disk write caching is enabled by default on all IS volumes.
5-5 Fusion-MPT Support
The BIOS uses the LSI Fusion-MPT interface to communicate to the SAS controller and
firmware to enable IS. This includes reading the Fusion-MPT configuration to gain
access to the parameters that are used to define behavior between the SAS controller
and the devices connected to it. The Fusion-MPT drivers for all supported operating
systems implement the Fusion-MPT interface to communicate with the controller and
firmware.
5-6 IS Configuration Overview
The SAS2 BIOS Configuration Utility is a menu-driven utility program that enables you
to easily configure and manage Integrated RAID volumes. You can use the SAS2 BIOS
Configuration Utility to create one or two Integrated Striping volumes on each SAS2
controller. Each volume can have from two-to-ten drives. All disks in an Integrated
Striping volume must be connected to the same SAS2 controller.
Although you can use disks of different size in Integrated Striping volumes, the smallest
disk in the volume determines the logical size of all disks in the volume. In other words,
the firmware does not use the excess space of the larger member disk(s). For example,
if you create an Integrated Striping volume with two 100-GB disks and two 120-GB
disks, the firmware uses only 100 GB on each of the larger disks for the volume. The
supported stripe size is 64 kilobytes.
5-7 Creating IS Volumes
The SAS2 BIOS Configuration Utility is part of the Fusion-MPT BIOS. When the BIOS
loads during boot and you see the message about the Configuration Utility, press
Ctrl-C
to start it. After you do this, the message changes to:
Please wait, invoking SAS Configuration Utility...
After a brief pause, the main menu of the SAS2 BIOS CU appears. On some systems,
however, the following message appears next:
LSI Configuration Utility will load following initialization!
