3.6 Using RAID Set/Volume Set Function
Method
In “Raid Set Function”, you can use the “Create Raid Set Function”
to generate a new RAID set. In “Volume Set Function”, you can
use the “Create Volume Set function” to generate an associated
volume set and and conguration parameters.
If the current controller has unused physical devices connected,
you can choose the “Create Hot Spare” option in the “Raid Set
Function” to dene a global hot spare. Select this method to con-
gure new raid sets and volume sets. The “Raid Set/Volume Set
Function” conguration option allows you to associate volume sets
with partial and full RAID sets.
3 The capacity for the current volume set is entered after highlighting the
desired RAID level and pressing the Enter key.
The capacity for the current volume set is displayed. Use the UP and
DOWN arrow keys to set the capacity of the volume set and press the
Enter key to conrm. The available stripe sizes for the current volume
set are then displayed.
4 Use the UP and DOWN arrow keys to select the current volume set
stripe size and press the Enter key to conrm. This parameter species
the size of the stripes written to each disk in a RAID 0, 1, 5 or 6 Volume
Set. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or
128 KB. A larger stripe size provides better read performance, especially
when the computer preforms mostly sequential reads. However, if the
computer preforms random read requests more often, choose a smaller
stripe size.
5 When you are nished dening the volume set, press the Enter key to
conrm the Quick Volume And Raid Set Setup function.
6 Foreground (Fast Completion) Press Enter key to dene fast initialization
or Selected the Background (Instant Available). In the background Ini-
tialization, the initialization proceeds as a background task, the volume
set is fully accessible for system reads and writes. The operating system
can instantly access to the newly created arrays without requiring a
reboot and waiting the initialization complete. In Fast Initialization, the
initialization proceeds must be completed before the volume set ready
for system accesses.
7 Initialize the volume set you have just congured.
8 If you need to add additional volume set, using main menu Create Vol-
ume Set function.
