 [LD No]

Indicates the number of the logical drive.

 [RAID Mode]

Indicates the RAID level of the logical drive.

 [Total Drv]

Indicates the number of HDDs configuring the logical drive.

 [Capacity]

Indicates the logical capacity of the configured logical drive in MB.

 [Status]

Indicates the status of the logical drive.

Status Description

Functional All the HDDs configuring the logical drive operate normally.

Critical One of the HDDs configuring the logical drive is in the offline

status. Because redundancy is lost, rebuild is required as soon

as possible. If another HDD is defected in the critical state,

data cannot be recovered any more.

Rebuilding The logical drive is being rebuilt.

Off Line More than one HDD configuring the logical drive are in the

offline status. In any offline logical drive, data processing is

disabled.
