6.5.7 Create Hot Spare
When you choose the “Create Hot Spare” option in the “Raid Set
Function”, all unused physical devices connected to the current
controller appear. Select the target disk by clicking on the ap-
propriate check box. Click the “Confirm The Operation” check
box and click the “Submit” button in the screen to create the hot
spares. The “Create Hot Spare” gives you the ability to define a
global or dedicated hot spare. Unlike “Global Hot Spare” which
can be used with any RAID sets, “Dedicated Hot Spare” can only
be used with a specific RAID set or Enclosure. Under “Global For
SSD or HDD” option, SSD hot spare is used to rebuild failed SSD
and HDD hot spare for rebuild failed HDD. When a disk drive fails
in the RAID set or enclosure with a dedicated hot spare is pre-set,
data on the disk drive is rebuild automatically on the dedicated
hot spare disk.
