5. Press the Spacebar to add the highlighted physical drive to the current
array. The indicator for the selected drive changes from Ready to Onlin A
[array number]-[drive number]. For example, Onlin A2-3 refers to array 2
drive 3.
Add physical drives to the current array as needed. Try to use drives of the
same capacity in the same array. If you use drives with different capacities
in an array, all the drives in the array are treated as though they have the
capacity of the smallest drive.
The number of physical drives in a specific array determines which RAID
levels can be implemented with the array.
6. Press Enter when you are finished creating the current array. The logical
drive configuration window appears.
The window shows the logical drive that is currently being configured as
well as any existing logical drives. 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 array
StrpSz The stripe size
Drive-State The state of the logical drive
7. Set the size of the logical drive. If you want to create more than one logical
drive in an array, set a size of less than the actual capacity.
8. To set the RAID level for the logical drive, highlight RAID and press
Enter. The available RAID levels for the current logical drive are
displayed. Select a RAID level and press Enter to confirm.
9. Select Advanced to set the stripe size, Write policy, Read policy, and
Cache policy.
•
Stripe size: This parameter identifies the size of the segment written to
each disk in a logical drive.
•
Write policy: This parameter identifies the cache write policy. You
can set the write policy to Write-Back or Write-Through.
•
Read policy: This parameter identifies the read policy for the logical
drive. You can set this parameter to Normal, Read-Ahead, or Adaptive.
