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 configuration parameters.
If the current controller has unused physical devices connected,
you can choose the “Create Hot Spare” option in the “Raid Set
Function” to define a global hot spare. Select this method to con-
figure new RAID sets and volume sets. The “Raid Set/Volume Set
Function” configuration 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 confirm. 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 confirm. This parameter specifies
the size of the stripes written to each disk in a RAID 0, 1, 10(1E), 5 or 6
volume set. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64
KB, 128 KB, 256 KB, 512 KB, or 1M. A larger stripe size provides better
read performance, especially when the computer preforms mostly se-
quential reads. However, if the computer preforms random read requests
more often, choose a smaller stripe size.
5 When you are finished defining the volume set, press the Yes key to
confirm the “Quick Volume And Raid Set Setup” function.
6 Foreground (Fast Completion) Press Enter key to define fast initialization
or selected the Background (Instant Available) or No Init (To Rescue Vol-
ume). In the “Background Initialization”, 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 “Foreground Initialization”, the initialization proceeds must be com-
pleted before the volume set ready for system accesses. In “No Init”,
there is no initialization on this volume.
7 Initialize the volume set you have just configured
8 If you need to add additional volume set, using main menu “Create Vol-
ume Set” function.
