5-46 Chapter 5: RAID conguration
5.6 LSI Logic MPT Setup Utility
(DSEB-DG/SAS model only)
The LSI Logic MPT Setup Utility is an integrated RAID solution that allows you to
allows you to create the following RAID set(s) from SAS hard disk drives supported
by the LSI1068 PCI-X SAS controller:
• RAID 1 (Integrated Mirroring)
• RAID 1E (Integrated Mirroring Enhanced)
• RAID 0 (Integrated Striping)
5.6.1 Integrated Mirroring
Overview
The Integrated Mirroring (IM) feature supports simultaneous mirrored volumes with
two disks (IM). Integrated Mirroring Enhanced (IME) supports three to eight disks,
or seven mirrored disks plus a hot spare disk.
The IM feature supports hot swap capability, so when a disk in an IM volume
failes, you can easily restore the volume, and the swapped disk is automatically re-
mirrored.
Creating Integrated Mirroring volumes
• You may use disks of different sized in IM and IME volumes; however, the
size of the smallest disk determines the “logical” size of each member disk.
• DO NOT combine Serial ATA and SAS disk drives in one volume.
• The RAID setup screens shown in this section are for reference only and
may not exactly match the items on your screen due to the controller
version difference.
To create an IM volume:
1. Turn on the system after installing all SAS hard disk drives.
2. During POST, press <Ctrl+C> to enter the SAS conguration utility.
