381-2. Notes on Creation of Logical Drive Setting hot-spare diskSuperBuild Utility cannot assign hot-spare disks. To assign hot-spare disks, use the disk arraycontroller management utility WebPAM after OS is installed.For free HDDs unassigned to any logical drives, standby rebuild can be performed but media patrolcannot. It is recommended to assign such free HDDs as spare disks by using WebPAM.CheckThe disk which has previously been configured as logical drive can besubject to media patrol even if it is in "free" status. Logical drive configuration using split functionThe disk array controller can make various logical drive configurations under the support of the splitfunction. However, note that some configurations may cause faults to occur. Examples ofrecommended and unsupported configurations of logical drives are described below.
