Ths secton descrbes how to create Integrated Mrrorng (IM) and Integrated Mrrorng
Enhanced (IME) volumes using the LSI Logic SAS BIOS Configuration Utility (SAS
BIOS CU).
3.1 IM Configuration Overview
You can use the SAS BIOS CU to create one or two IM or IME volumes on each LSI
Logc SAS controller, wth an optonal global hot spare dsk. All dsks n an IM or IME
volume must be connected to the same LSI Logc SAS controller.
Although you can use dsks of dfferent sze n IM and IME volumes, the smallest dsk
determnes the “logcal” sze of each dsk n the volume. In other words, the excess
space of the larger member dsk s not used.
Refer to Secton 2.2, “IM Features,” for more nformaton about Integrated Mrrorng
volumes.
3�2 Creating IM and IME Volumes
The SAS BIOS CU s part of the Fuson-MPT BIOS. When the BIOS loads durng boot
and you see the message about the LSI Logic Configuration Utility, press Ctrl-C to start
the CU. After you do ths, the message changes to:
Please wait, invoking SAS Configuration Utility...
After a bref pause, the man menu of the SAS BIOS CU appears. On some systems,
however, the followng message appears next:
LSI Logic Configuration Utility will load following initialization!
In ths case, the SAS BIOS CU wll load after the system has completed ts power-on
self test.
You can configure one or two IM or IME volumes per Fusion-MPT controller. You can
also combne IM, IME, and Integrated Strpng volumes on the same controller, up to a
maxmum of 10 physcal dsk drves.
The followng gudelnes also apply when creatng an IM or IME volume:
All physcal dsks n the volumes must be ether SATA (wth extended command set
support) or SAS (wth SMART support). SAS and SATA dsks cannot be combned
n the same volume.
Dsks must have 512-byte blocks and must not have removable meda.
An IM volume must have two drves, plus an optonal global hot spare. An IME
volume. An IME volume can have three to eght drves, or three to seven drves f
you also create a global hot spare.
