2. Press the arrow keys to highlight specific physical drives.
3. 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 hard drive 3 in array 2.
4. Add physical drives to the current array as desired.
NOTE: 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 determine the RAID levels that can be
implemented with the array.
RAID 0 requires one or more physical drives per array.
RAID 1 requires two physical drives per array.
RAID 10 requires at least four physical drives per array.
NOTE: Dell™ does not recommend using RAID 0 in the cluster environment. RAID 0 is
not redundant and provides no data protection.
5. Press <Enter> after you finish creating the current array.
A window entitled Select Configurable Array(s) appears. It displays the array, and array
number, such as A-00.
6. Press the spacebar to select the array.
Span information, such as Span-1, displays in the array box. You can create multiple
arrays, then select them to span them.
NOTE: You can press <F2> to display the number of drives in the array, their channel
and ID, and <F3> to display array information, such as the stripes, slots, and free space.
7. Press <F10> to configure a logical drive.
The logical drive configuration screen appears. Span=Yes displays on this screen if you
select two or more arrays to span.
The logical drive that is currently being configured and any existing logical drives
display. The column headings are:
LD The logical drive number
RAID The RAID level
Size The logical drive size
#Stripes The number of stripes (physical drives) in the associated physical array
StrpSz The stripe size
Drive-State The state of the logical drive
