Step Action
1 To setup the hot spare (option), choose “Raid Set Function” from the main
menu. Select the “Create Hot Spare” and press the Enter key to define
the hot spare.
2 Choose “Raid Set Function” from the main menu. Select “Create Raid Set”
and press the Enter key.
3 The “Select a Drive For Raid Set” window is displayed showing the SAS/
SATA drives connected to the SAS RAID controller.
4 Press the UP and DOWN arrow keys to select specific physical drives.
Press the Enter key to associate the selected physical drive with the cur-
rent RAID set.
It is recommended that you use drives of the same capacity in a specific
array. If you use drives with different capacities in an array, all drives in
the RAID set will be set to the capacity of the smallest drive in the RAID
set.
The numbers of physical drives in a specific array determines which RAID
levels that can be implemented in the array.
RAID 0 requires 1 or more physical drives.
RAID 1 requires at least 2 physical drives.
RAID 10(1E) requires at least 3 physical drives.
RAID 3 requires at least 3 physical drives.
RAID 5 requires at least 3 physical drives.
RAID 6 requires at least 4 physical drives.
RAID 30 requires at least 6 physical drives.
RAID 50 requires at least 6 physical drives.
RAID 60 requires at least 8 physical drives.
5 After adding the desired physical drives to the current RAID set, press the
Enter to confirm the “Create Raid Set” function.
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.
