Using Easy Configuration In Easy Configuration, each array is associated with exactly one logical drive. Follow the steps below to create arrays using Easy Configuration. The following graphics often show 2 or 3 SCSI channels. MegaRAID Explorer supports up to 4 SCSI channels. Step Action 1 Choose Configure from the MegaRAID Configuration Utility main menu. 2 Choose Easy Configuration from the Configure menu. The array selection menu appears: Hot key information is displayed at the bottom of the screen. The hot key functions are: Display the manufacturer data and error count for the selected drive. Display the logical drives that have been configured. Designate the selected drive as a hot spare. 3 Press the arrow keys to choose specific physical drives. Press the spacebar to associate the selected physical drive with the current array. The indicator for the selected drive changes from READY to ONLIN A[array number]-[drive number]. For example, ONLIN A2-3 means disk drive 3 in array 2. Add physical drives to the current array as desired. Try to use drives of the same capacity in a specific array. If you use drives with different capacities in an array, all drives in the array are treated as if they have the capacity of the smallest drive in the array. The number of physical drives in a specific array determines the RAID levels that can be implemented with the array. RAID 0 requires one or more physical drives. RAID 1 requires exactly two physical drives. RAID 3 requires at least three physical drives. RAID 5 requires at least three physical drives. Cont'd Chapter 2 MegaRAID Configuration Utility 19

Using Easy Configuration
In Easy Configuration, each array is associated with exactly one logical drive.
Follow the steps below to create arrays using Easy Configuration. The following
graphics often show 2 or 3 SCSI channels. MegaRAID Explorer supports up to 4
SCSI channels.
Step
Action
1
Choose Configure from the MegaRAID Configuration Utility main menu.
2
Choose Easy Configuration from the Configure menu. The array selection menu appears:
Hot key information is displayed at the bottom of the screen. The hot key functions are:
<F2>
Display the manufacturer data and error count for the selected
drive.
<F3>
Display the logical drives that have been configured.
<F4>
Designate the selected drive as a hot spare.
3
Press the arrow keys to choose specific physical drives. Press the spacebar to associate
the selected physical drive with the current array. The indicator for the selected drive
changes from READY to ONLIN A[
array number
]-[
drive number
]. For example,
ONLIN A2-3 means disk drive 3 in array 2.
Add physical drives to the current array as desired. Try to use drives of the same capacity
in a specific array. If you use drives with different capacities in an array, all drives in the
array are treated as if they have the capacity of the
smallest
drive in the array.
The number of physical drives in a specific array determines the RAID levels that can be
implemented with the array.
RAID 0 requires one or more physical drives.
RAID 1 requires exactly two physical drives.
RAID 3 requires at least three physical drives.
RAID 5 requires at least three physical drives.
