3.2 Creating IM and IME 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 Configuration
Utility, press Ctrl-C to start the CU. After you do this, the message
changes to:
Please wait, invoking SAS Configuration Utility...
After a brief pause, the main menu of the SAS BIOS CU appears. On
some systems, however, the following message appears next:
LSI Configuration Utility will load following
initialization!
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 configure one IM/IME and one Integrated Striping
(IS) volume on the same controller, up to a maximum of twelve physical
disk drives for the two volumes. In addition, you can create one or two
hot spares for the IM/IME array(s).
The following guidelines also apply when creating an IM or IME volume:
•
All physical disks in a volume must be either SATA (with extended
command set support) or SAS (with SMART support). SAS and
SATA disks cannot be combined in the same volume. However, you
can create one volume with SAS disks and a second volume with
SATA disks on the same controller.
•
Disks must have 512-byte blocks and must not have removable
media.
•
An IM volume must have two drives. An IME volume can have three
to ten drives. In addition, one or two hot spares can be created for
the IM/IME volume(s).
Note: If a disk in an IM/IME volume fails, it is rebuilt on the global
hot spare if one is available. LSI recommends that you
always use hot spares with IM/IME volumes.
