Step 2 Execute "

mklds

" command with the

following parameters.

-c

: Number of the RAID Controller in which a Logical Drive

is created

-p

: Numbers of the Physical Devices with which a Logical

Drive is created (The required number of Physical Devices

varies depending on the RAID Level of the Logical Drive to

be created).

-rl

: RAID Level at which a Logical Drive is made ("Create

Logical Drive - Simple Mode" allows a Logical Drive with

RAID Level being RAID 1 or RAID 5 to be created)

Ex. Create RAID 5 Logical Drive in the Simple Mode using Physical Devices (RAID Controller Number:1 and Physical

Devices e252s2, e252s3, and e252s4).

raidcmd mklds -c=1 -p=e252s2,e252s3,e252s4 -rl=5

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.

Physical Devices Available for "Create Logical Drive - Simple

Mode"

Unused Physical Devices are available for "Create Logical Drive - Simple Mode".

Physical Devices in which S.M.A.R.T. errors are detected cannot be used to create Logical

Drives.

Unused Physical Devices are those with their [Status] being

[Ready].

Creating Logical Drives by "Create Logical Drive - Simple

Mode"

This section describes the information on Logical Drives to be created by "Create Logical Drive - Simple Mode".

RAID Level

The RAID Level of a Logical Drive which can be created by "Create Logical Drive - Simple Mode" should be

RAID 1 or RAID 5.

Capacity of Logical Drive

The capacity of a Logical Drive to be created is defined by the RAID Level and the capacities of Physical

Devices used for the Logical Drive. In "Create Logical Drive - Simple Mode", a Logical Drive is created by using

the entire areas of the Physical Devices.

Items set for Logical Drive

The values of other selection items set for a Logical Drive to be created are defined as shown in the table

below.

Selection item

Value

Stripe Size Uses the default value set for the RAID Controller. (The value varies depending on the

type of the RAID Controller.)

Cache Mode Uses the default value set for the RAID Controller. (The value varies depending on the

type of the RAID Controller.)

Initialize Mode Full

> raidcmd mklds -c=1 -p=e252s2,e252s3,e252s4 -rl=5

raidcmd creates Logical Drive #1.

Do you continue ? [yes(y) or no(n)] : yes

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.
