Allows Global or Dedicated Hot Spare to be made without errors. Would like to configure RAID System easily due to no expert knowledge of RAID System.
Making Hot Spare The Universal RAID Utility can make a Hot Spare to be replaced with a Physical Device in which a failure occurs. Hot spares can have the following two modes. Mode Description Global (Hot Spare) Available as a Hot Spare of every Disk Array for a single RAID Controller. Dedicated (Hot Spare) Available as a Hot Spare of a specific Disk Array for a single RAID Controller. In either mode, note the following to have a Hot Spare operate normally.
About Dedicated Hot Spare Dedicated Hot Spare is a Hot Spare for the specified Disk Arrays under a single RAID Controller. The Dedicated Hot Spare has the following features: Dedicated Hot Spare is a Hot Spare for specified Disk Arrays. One Dedicated Hot Spare can be a Hot Spare for one or more Disk Arrays. One or more Dedicated Hot Spare can be a Hot Spare for one or more Disk Arrays. Dedicated Hot Spares cannot be created in a Disk Array containing Logical Drives with the RAID Level being RAID 0.
Disk Array #1 Disk Array #2 Dedicated Hot Spare #1 Dedicated Hot Spare #2 Figure 14 Dedicated Hot Spare 3 Ex 4 : In case of the RAID System in Ex2, you can add more Dedicated Hot Spare likely Ex2. If you add the Dedicated Hot Spare to the Disk Arrays #1 and #2, the both Dedicated Hot Spare are the Hot Spare for the Disk Arrays #1 and #2.
raidcmd Step 1 Execute "hotspare" command with –mr option and the following parameters. -c : Number of the RAID Controller containing the Physical Device with which a Hot Spare is made -p : Number of the Physical Device with which a Global Hot Spare is made -mr : Specify "make" to make Global Hot Spare Ex. Create a Global Hot Spare using the Physical Device with RAID Controller:1 and Physical Device number:e252s5.
Step 4 If the Dedicated Hot Spare is created successfully, you can find that the value of [Status] is set to [Hot Spare] and item [Hot Spare Information] appears newly with value [Dedicated (Disk Array #X)]. raidcmd Step 1 Execute "hotspare" command with -mr option and the following parameters.

Remove a Hot Spare with RAID Controller number: 1 and Physical Device number: e252s5.
Configuring RAID System Easily The Universal RAID Utility supports the Easy Configuration function allowing configurations such as creating Logical Drive and making a Hot Spare to be provided in the state where unused Physical Devices are connected to RAID Controllers.
Step 4 In step 2/3, specify the number of Physical Devices used by Logical Drives (or the number of Physical Devices used for data storage) and the number of Logical Drives created in the RAID Controller. If Physical Devices of different interface types or device type exist, specify the number of Physical Devices in each type. After the specification, click [Next]. Step 5 Step 3/3 shows the configuration of the RAID System to be configured by the Easy Configuration.
raidcmd Step 1 Connect Physical Devices used for Easy Configuration to the RAID Controller before executing raidcmd if required. Step 2 2 > raidcmd econfig Step 1/3 : Select RAID Controller RAID Controller #1 LSI MegaRAID SAS 9267-8i Execute "econfig" command. RAID Controller [1] :1 Step 3 Specify the conditions on Easy Configuration. In step 1/3, select the RAID Controller to be configured. Enter the RAID Controller number to be configured.
RAID Controller Enabling Easy Configuration to Be Executed Any RAID Controller enabling Easy Configuration to be executed must meet the following conditions. 1. Allowing Dedicated Hot Spares to be made. 2. Connecting with more than one unused Physical Devices which have the same sector format. Physical Devices Available for Easy Configuration Only unused Physical Devices are available for Easy Configuration. Unused Physical Devices are those with their [Status] being [Ready].
Physical Devices used for Logical Drives Physical Devices of lower Physical Device Numbers are used preferentially for Logical Drives to be created excluding those for making Hot Spares. Ex. : If Physical Devices 1 - 7 can be used for Easy Configuration, Logical Drives #1 is created with Physical Devices 1, 2, and 3 in the ascending order of Physical Device Numbers and Logical Drives #2 is created with Physical Devices 4, 5, and 6. Physical Device 7 (the largest number) is used as a Hot Spare.
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. The Easy Configuration uses the entire areas of the Physical Devices to create a Logical Drive. Ex.: If Physical Devices 1 - 7 can be used in Easy Configuration to create two Logical Drives, use Physical Devices 1 - 4 and 5 - 7 to create Logical Drives #1 and #2, respectively.
Making Hot Spares by Easy Configuration This section describes the information on Hot Spares to be made by the Easy Configuration. Number of Hot Spares The number of Hot Spares is defined by the number of unused Physical Devices connected to the RAID Controller and the number of Physical Devices used for Logical Drives. The number of Hot Spares results from subtracting [Number of Physical Devices specified for Logical Drives] from [Unused Physical Device count] in step 2/3 of the [Easy Configuration...
Modes of Hot Spares The Easy Configuration can only make Dedicated Hot Spares but cannot make Global Hot Spares. If more than one Logical Drive is created, the Dedicated Hot Spare can be used for all Logical Drives to be created. Ex.: If Physical Devices 1 - 7 are used in Easy Configuration to create two Logical Drives and a single Hot Spare, the Hot Spare will be the Dedicated Hot Spare for each Logical Drive.
Creating Logical Drive Easily The Universal RAID Utility supports "Create Logical Drive - Simple Mode" in which a Logical Drive can be created only by selecting two selection items according to the guide. "Create Logical Drive - Simple Mode" allows you to create a Logical Drive only by specifying two selection items, or the RAID Level of the Logical Drive and Physical Devices to be used. The benefits of creating a Logical Drive with "Create Logical Drive - Simple Mode" are as follows.
Step 4 In step 2/3, select Physical Devices to be used to create the Logical Drive. If Physical Devices of different types or Sector Format exist in the RAID Controller, click the type or Sector Format to be used on [Type] or [Sector Format]. Next, check the check boxes of Physical Devices to be used on [Physical Device]. You must select Physical Devices to be used by the number allowing the RAID Level selected in Step 1/3 to be created. After selecting Physical Devices properly, click [Next].
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).
Creating Logical Drive Freely The Universal RAID Utility supports "Create Logical Drive - Custom Mode" in which a Logical Drive can be created as required by specifying the setting items of the Logical Drive closely. "Create Logical Drive - Custom Mode" allows you to create a Logical Drive by specifying the setting items of the Logical Drive closely. It can also be used to create Logical Drives of several RAID Levels or create a Logical Drive by using unused area of Disk Array.
Step 4 If you click [Add] in the [Create Logical Drive (Custom)] dialog box, the [Register Logical Drive] wizard is started. In step 1/3, select the RAID Level of the Logical Drive to be registered. After the selection, click [Next]. Step 5 In step 2/3, the operation varies depending on the RAID Level selected in step 1/3. (1) When RAID 0, RAID 1, RAID 5, or RAID 6 is selected as the RAID Level, select an existing Disk Array or create another Disk Array.
Step 6 In step 3/3, select the setting items of the Logical Drive to be registered. [Capacity] should be a value within the Capacity of the Logical Drive to be created. If the RAID Level of the Logical Drive to be created is RAID 10, RAID 50 or RAID 60, you do not have to enter the value. Select [Stripe Size], [Cache Mode] and [Initialize Mode]. After selecting all the setting items, click [Next]. Step 7 If you click [Next] in step 3/3, then [Completing the "Register Logical Drive" Wizard] will appear.
raidcmd Physical Devices used for creating a Logical Drive should have the same sector format. 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. > raidcmd mkldc -c=1 -p=e252s2,e252s3,e252s4 -rl=5 -cp=20 -ss=64 -cm=auto -im=full raidcmd creates Logical Drive #1.
Logical Drive with RAID Level being RAID 10, RAID 50, RAID 60 Only unused Physical Devices are available for Logical Drives (only RAID Viewer). Disk Arrays containing empty areas or unused Physical Devices are available for creating a Logical Drive (only raidcmd). Creating Logical Drives by "Create Logical Drive - Custom Mode" This section describes the information on Logical Drives to be created by "Create Logical Drive - Custom Mode".
Deleting Logical Drive The Universal RAID Utility can delete a Logical Drive becoming unnecessary. The function of deleting a Logical Drive is available only in the Advanced Mode. Before deleting a Logical Drive, check if the Logical Drive contains required data. Deleting a Logical Drive causes all the data saved in the Logical Drive to be lost. You can delete Logical Drive with partitions. You can delete only the Logical Drive that is located at the end of Disk Array.
