raidcmd
A count of Logical Drive created by raidcmd is 1 at same time.
Step 1
Connect Physical Devices used for a Logical Drive to the RAID Controller before executing raidcmd if required.
Step 2 Execute "mkldc" command with the
following parameters.
-c : Number of the RAID Controller in which a Logical
Drive is created
-p : Numbers of the Physical Devices used to create a
Logical Drive if used(The required number of Physical
Devices varies depending on the RAID Level of the Logical
Drive to be created)
-a : Number of the Disk Array used to create a Logical Drive
if used
-rl : RAID Level of a Logical Drive to be created("Create
Logical Drive - Custom Mode" allows a Logical Drive with
RAID Level being RAID 0 RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, RAID 60 to be created)
-cp : Capacity of a Logical Drive to be created.(This value may be omitted if a Logical Drive is created by using the whole area of unused
Physical Devices. You do not specify this option when you create an RAID10, RAID 50 or RAID 60 Logical Drive.)
-ss : Stripe Size of a Logical Drive to be created(This value may not be specified if the default value for the RAID Controller is used)
-cm : Cache Mode of a Logical Drive to be created(This value may not be specified if the default value for the RAID Controller is used)
-im : Operation mode for Initialize executed after a Logical Drive is created(The [Full] mode is recommended. In the [Full] mode, the
Initialize Mode may not be specified)
Ex. Create a Logical Drive (RAID5, 20GB, 64 KB stripe size, Auto Switch Cache Mode, and Full Initialization Mode) in the Custom Mode
using Physical Devices (RAID Controller Number: 1 and Physical Devices e252s2, e252s3, and e252s4).
raidcmd mkldc -c=1 -p=e252s2,e252s3,e252s4 -rl=5 -cp=20 -ss=64 -cm=auto -im=full
raidcmd created Logical Drive #1, and started to initialize
it.
You can see the progress and the result of initialize by
"oplist" and "property" commands.
>
> raidcmd mkldc -c=1 -p=e252s2,e252s3,e252s4 -rl=5 -cp=20
-ss=64 -cm=auto -im=full
raidcmd creates Logical Drive #1.
Do you continue ? [yes(y) or no(n)] : yes

Step 3 Type "yes" to reply to the confirmation message. Then a Logical Drive is created.
Step 4 After the Logical Drive is created successfully, the raidcmd terminates normally. The Logical Drive has been
created completely. You can check the information on the Logical Drive by using "property" command. However, the
Initialize of the Logical Drive having been created may not be completed. The progress of initializing the Logical Drive can
be checked by using "oplist" command. The result of initializing the Logical Drive can be checked by RAID Log.
Disk Arrays and Physical Devices Available for "Create
Logical Drive - Custom Mode"
For "Create Logical Drive - Custom Mode", Disk Arrays or unused Physical Devices are available depending on the
RAID Level of the Logical Drive to be created.
 Physical Devices in which S.M.A.R.T. errors are detected cannot be used to create Logical
Drives.
 Disk Array which does not have any Logical Drive cannot be used to create Logical Drives.
Unused Physical Devices are those with their [Status] being [Ready].
Logical Drive with RAID Level being RAID 0, RAID 1, RAID 5 or RAID 6
Disk Arrays containing empty areas or unused Physical Devices are available for creating a Logical Drive with the
RAID Level being RAID 0, RAID 1, RAID 5, or RAID 6.
Among empty areas in a Disk Array, the empty area existing at the end of the Disk Array can be used. The RAID
Level of a Logical Drive to be created must be the same as that of the Logical Drives existing in the area used on
the Disk Array.
If unused Physical Devices are used, create a Disk Array and create a Logical Drive on it.
Logical Drive with RAID Level being RAID 10, RAID 50, RAID 60
82
Only unused Physical Devices are available for Logical Drives with RAID Level being RAID 10, RAID 50 or
RAID 6
