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 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 or RAID 50 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,e25 -rl=5 -cp=20

-ss=64 -cm=auto -im=full

2s4

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 or RAID 50

Only unused Physical Devices are available for Logical Drives with RAID Level being RAID 10 or RAID 50.
