1-2. Notes on Creation of Logical Drive

„Setting hot-spare disk

FastBuild Utility cannot set hot-spare disks. To set 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 done but media patrol cannot. It is recommended to specify such free HDDs as spare disks by using WebPAM.

„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.
