1-2. Notes on Creation of Logical Drive
Setting hot-spare disk
SuperBuild Utility cannot assign hot-spare disks. To assign hot-spare disks, use the disk array
controller management utility WebPAM after OS is installed.
For free HDDs unassigned to any logical drives, standby rebuild can be performed but media patrol
cannot. It is recommended to assign such free HDDs as spare disks by using WebPAM.
The disk which has previously been configured as logical drive can be
subject to media patrol even if it is in "free" status.
Check
Logical drive configuration using split function
The disk array controller can make various logical drive configurations under the support of the split
function. However, note that some configurations may cause faults to occur. Examples of
recommended and unsupported configurations of logical drives are described below. See the
examples before creating logical drives.
