Physical Devices Available for Easy Configuration
Only unused Physical Devices are available for Easy Configuration. Unused Physical Devices are those with their
[Status] being [Ready].
Creating Logical Drives by Easy Configuration
Logical Drives created by Easy Configuration are described below.
RAID Levels and the number of Logical Drives allowed to be created
The RAID Level of a Logical Drive created by Easy Configuration should be RAID 1 or RAID 5. Whether RAID 1
or RAID 5 is used is defined by RAID Levels supported by the RAID Controller and the number of Physical
Devices used by the Logical Drive.
The number of Logical Drives allowed to be created is also defined by the similar conditions.

RAID Level of Logical Drive

2 RAID 1 1
3 - 5 RAID 5 1
6 or more RAID 5 Number of Physical Devices used by Logical Drive / 3

RAID Level of Logical Drive
Number of Logical Drives allowed to be created
2 or more RAID 1 Number of Physical Devices used by Logical Drive / 2
The Easy Configuration can only create Logical Drives of RAID 1 or RAID 5.
Physical Devices used for Logical Drives
Physical Devices of lower Physical Device Numbers are used preferentially for Logical Drives to be created
excluding those for making Hot Spares.
Ex. : If Physical Devices #1 - #7 can be used for Easy Configuration and Physical Device #3 is used as a Hot
Spare, Logical Drives #1 and #2 are created with Physical Devices #1 and #2 having lower Physical Device
Numbers and Physical Devices #5, #6 and #7, respectively.
Figure 15 Assigning Physical Devices in Easy Configuration 1
If more than one Logical Drive are created and the number of Physical Devices configuring a Logical Drive is
not equal to others, a larger number of Physical Devices should be assigned to a Logical Drive having a
smaller logical number.
