raidcmd
Description
Number RAID Controller #X
Logical Drive #Y
Indicates the management number (logical address) of the Logical Drive in the
Universal RAID Utility.
The Universal RAID Utility assigns a number beginning with 1 in correspondence
with the value of [ID].
ID ID Indicates the original identification value of the Logical Drive. Use this value to
create Logical Drives managed by the RAID Configuration utility of the RAID
Controller correspond with those managed by the Universal RAID Utility.
Disk Array
Information
Disk Array
Information
Indicates the number of the Disk Array in which the Logical Drive exists and the
information on the location in the Disk Array. The information is displayed in the
following format.
<RAID Viewer>
Disk Array number (sequence number starting from the top / sequence number
of Logical Drive in Disk Array)
<raidcmd>
Disk Array number (order sequence number starting from the top / sequence
number of Logical Drive in Disk Array)
RAID Level RAID Level Indicates the RAID Level of the Logical Drive.
The value can be RAID 0, RAID 1, RAID 5, RAID 6, RAID 00, RAID 10, RAID 1E,
RAID 50 or RAID 60.
Displayed only when Type is Logical Drive.
Sector Format Sector Format Indicates the Sector Format of the Logical Drive.
The value can be 512, 512e or 4Kn by the Sector Format of Physical Devices
which are the members of Logical Drive.
Capacity Capacity Indicates the capacity of the Logical Drive in GB.
Type Type Type of the Logical Drive.
Indicates Logical Drive or SSD Cache Drive.
Stripe Size Stripe Size Indicates the Stripe Size of the Logical Drive.
The value can be 1KB, 2KB, 4KB, 8KB, 16KB, 32KB, 64KB, 128KB, 256KB,
512KB, or 1024KB.
Displayed only when Type is Logical Drive.
Cache Mode
(Setting)
Cache Mode
(Setting)
Indicates the mode of writing data to the cache memory installed in the RAID
Controller.
Three possible modes are as follows:
Auto Switch: Switches the mode automatically between Write Back and Write
Through depending on the existence and/or status of Battery and Flash Backup
Unit. For onboard RAID Controller (LSI Embedded MegaRAID), it is set as Write
Back.
Write Back: Writes data to the cache memory asynchronously.
Write Through: Writes data to the cache memory synchronously.
Displayed only when Type is Logical Drive.
Cache Mode
(Current)
Cache Mode
(Current)
Indicates the current value of the mode of writing data to the cache memory
installed in the RAID Controller. For onboard RAID Controller (LSI Embedded
MegaRAID), it indicates the current status of the HDD Write Cache.
Two possible modes are as follows:
Write Back: Writes data to the cache memory asynchronously.
Write Through: Writes data to the cache memory synchronously.
Displayed only when Type is Logical Drive.
Status Status Indicates the status of the Logical Drive.
Three possible status are as follows:
Online: Indicates that the redundancy of the Logical Drive is retained.
Degraded: Indicates that the redundancy of the Logical Drive is lost or degraded.
Accessing to the Logical Drive is enabled.
Offline: Indicates that the Logical Drive is offline and accessing to the Logical
Drive is disabled.
