5.2.3    Creating Integrated Mirroring Volumes 

This section describes how to create Integrated Mirroring (IM) and Integrated Mirroring Enhanced (IME) 

volumes using the LSI Logic SAS BIOS Configuration Utility (SAS BIOS CU). 

 

You can use the SAS BIOS CU to create one or two IM or IME volumes on each LSI Logic SAS controller, 

with an optional global hot spare disk. All disks in an IM or IME volume must be connected to the same 

LSI Logic SAS controller. 

 

Although you can use disks of different size in IM and IME volumes, the smallest disk determines the 

“logical” size of each disk in the volume. In other words, the excess space of the larger member disk is not 

used. 

 

Refer to Section 2.2, “IM Features,” for more information about Integrated Mirroring volumes. 

 

 

The SAS BIOS CU is part of the Fusion-MPT BIOS. When the BIOS loads during boot and you see the 

message about the LSI Logic Configuration Utility, press Ctrl-C to start the CU. After you do this, the 

message changes to: 

 

 

After a brief pause, the main menu of the SAS BIOS CU appears. On some systems, however, the following 

message appears next: 

 

In this case, the SAS BIOS CU will load after the system has completed its power-on self test. 

 

You can configure one or two IM or IME volumes per Fusion-MPT controller. You can also combine IM, IME, 

and Integrated Striping volumes on the same controller, up to a maximum of 10 physical disk drives.
