Creating Im And Ime Volumes - Intel AFCSASRISER User Manual

•
Easy-to-use BIOS-based configuration utility.
•
Error notification: The drivers update an OS-specific event log.
•
LED status support.
•
Write journaling, which allows automatic synchronization of potentially
inconsistent data after unexpected power-down situations.
•
Metadata used to store volume configuration on mirrored disks.
•
Automatic background resynchronization while the host continues to process
inputs/outputs (I/Os).
Background media verification ensures that data on IM/IME volumes is always
accessible.

Creating IM and IME Volumes

The LSI MPT* SAS BIOS Configuration Utility is part of the Fusion-MPT* BIOS. When
the BIOS loads during boot and you see the message about the LSI MPT* SAS BIOS
Configuration Utility, press <Ctrl> + <C> to start the utility. The message then changes
to:
Please wait, invoking LSI SAS Configuration Utility...
After a brief pause, the main menu appears. On some systems, however, the following
message appears:
Configuration Utility will load following initialization!
In this case, the LSI MPT* SAS BIOS Configuration Utility loads after the system has
completed a 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 12 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.
Intel recommends that you always use hot spares with IM/IME volumes.
