- Warning
One or more Physical Devices in the warning condition exist in the SSD
Cache Disk Array.
SSD Cache Disk Array
- Fatal
One or more Physical Devices in the warning or fatal condition exist in the
SSD Cache Disk Array.
Logical Drive

number, status and RAID Level of the Logical Drive.
[Icon] LD #<Number> [<Status>] <RAID Level>
Item Description
<Number> Indicates the management number (logical address) of the Logical Drive in the Universal
RAID Utility.
<Status> Indicates the status of the Logical Drive.
<RAID Level> Indicates the RAID Level of the Logical Drive.
A Logical Drive icon indicates the status of the Logical Drive.
Icon Meaning Description
Logical Drive - Normal The Logical Drive operates normally.
Logical Drive - Warning Because the Logical Drive contains one or more Physical Devices with Status
being Failed, the redundancy of the Logical Drive is lost or degraded.
Logical Drive - Fatal Because the Logical Drive contains one or more Physical Devices with Status
being Failed, the Logical Drive is offline and accessing to the Logical Drive is
disabled.
A RAID10/RAID50/RAID60 Logical Drive consists of more than one Disk Array according to
the type of the RAID Controller. Such Logical Drive nodes are located in more than one Disk
