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 or RAID 50, you may not 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 Use "mkldc" command. 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 at this timing if required. Step 2 Execute "mkldc" command with the following parameters.
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". RAID Levels The RAID Level of a Logical Drive which can be created by "Create Logical Drive - Custom Mode" should be RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, or RAID 50. Supported RAID Levels vary in RAID Controllers. Unsupported RAID Levels cannot be selected.
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. You can delete Logical Drive with partitions. 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 only the Logical Drive that is located at the end of Disk Array.
Maintenance of RAID System This chapter describes the maintenance of a RAID System using the Universal RAID Utility. Providing Patrol Read for Physical Devices The Patrol Read function reads data saved in all Physical Devices in a RAID System entirely to check whether a read error occurs or not regularly in the background. The Patrol Read is effective to find failures including Physical Device medium error early. Be sure to execute Patrol Read for a RAID Controller if it supports the Patrol Read.
Checking Result of Executing Patrol Read You can find the result of executing Patrol Read by checking the RAID Log of the Universal RAID Utility. When detects something problem, Universal RAID Utility records the log in the RAID Log. Setting Patrol Read Priority You can set the priority in which Patrol Read is executed in your computer. The procedure of setting the Patrol Read Priority is described below. Changing the priority of Patrol Read is available only in the Advanced Mode.
Checking Logical Drive Consistency The Consistency Check function checks the consistency between the data in the data area of a Logical Drive and the parity. The Universal RAID Utility can start or stop Consistency Check and change the priority in which Consistency Check is executed. The Consistency Check is effective next to Patrol Read to find failures including Physical Device medium error early. Execute Consistency Check periodically if the RAID Controller does not support Patrol Read.
Executing Consistency Check for arbitrary Logical Drive The Universal RAID Utility makes a task for scheduled execution of Consistency Check so that a RAID Controller not supporting Patrol Read can find failures including medium error early. To execute Consistency Check for arbitrary Logical Drive by raidcmd, use the function of scheduler as Task of Windows or cron of Linux and VMware ESX.
Stopping Consistency Check You can stop Consistency Check being executed on the way. The procedure of stopping Consistency Check is described below. RAID Viewer Use [Stop] on Operation View. Step 1 Start the RAID Viewer. See [Operation View] while Consistency Check is executed. Step 2 Click operation [Consistency Check] which you want to stop. Click [Stop] on the Operation View. After the Consistency Check is stopped, [Status] on the Operation View is changed to [Stopped]. 2 raidcmd Use "cc" command.
raidcmd Use "optctrl" command. Step 1 Execute "optctrl" command with -ccp option and the following parameters. -c : Number of the RAID Controller for which Consistency Check Priority is set -ccp : Value set after Consistency Check Priority is set(Select a value out of high, middle, and low) Step 2 Check the execution result by using "property" command.
Initializing Logical Drive The Initialize writes 0s into the entire area of a Logical Drive to erase the data saved in the Logical Drive. Use the function when you want to erase the data saved in a Logical Drive fully. Initialize has two modes listed in the table below. Mode Description Full Writes 0s into the entire area of a Logical Drive to erase the data fully. Quick Writes 0s into some blocks in a Logical Drive. Only erases OS installation and partition management information.
Step 3 After Initialize is started, the progress of the Initialize appears on the Operation View. At the completion of the Initialize, [Status] on the Operation View is changed to [Completed]. raidcmd Use "init" command. Step 1 Execute "init" command with -op option and the following parameters.
Setting Initialize Priority You can set the priority at which Initialize is executed in the computer. The procedure of setting the Initialize Priority is described below. Setting Initialize Priority are available only in the Advanced Mode. RAID Controllers of some types may not support the setting Initialize Priority. If does not support this function, RAID Viewer and raidcmd do not display this item in the property of RAID Controller and the execution of "optctrl" command of raidcmd fails.
Changing Cache Mode of Logical Drive You can change the cache mode of Logical Drive. The setting of the cache mode of Logical Drive influences the performance of computer. Please change carefully. Changing cache mode The procedure of changing cache mode of Logical Drive is described below. The range of change differs depending on the type of the RAID Controller.
Rebuilding Physical Device Rebuild means incorporation of a new Physical Device to a Logical Drive after a Physical Device is replaced with the new one due to occurrence of an event such as a failure. In general, the Rebuild is automatically started by a function of the RAID Controller called standby rebuild or hot-swap rebuild. Accordingly, manual Rebuild is not required so often. If required, use the Universal RAID Utility. Manual Rebuild is available only in the Advanced Mode.
Step 3 After the Rebuild is started, the raidcmd terminates normally. Check the execution status of the Rebuild by using "oplist" command. Stopping Rebuild You can stop Rebuild being executed on the way. The procedure of stopping Rebuild is described below. The function of stopping Rebuild is available only in the Advanced Mode. Some types of RAID Controller do not support stopping rebuild. If it does not support this function, the stop button of operation view of RAID Viewer does not become enable.
Setting Rebuild Priority You can set the priority at which Rebuild is executed in the computer. The procedure of setting the Rebuild Priority is described below. Setting Rebuild Priority are available only in the Advanced Mode. RAID Viewer Change the property of RAID Controller. Step 1 Start the RAID Viewer. Click the RAID Controller on the Tree View. Then click [Properties] on the pull-down menu of menu item [File]. Step 2 Click the [Options] tab in the [RAID Controller Properties] dialog box.
Checking Location of Physical Device The locate function can be used when you want to know the slot to which a specific Physical Device appearing in the RAID Viewer is inserted in the computer or enclosure. In actual, locate turns on the DISK lamp on the computer or enclosure in which the specified Physical Device is installed. (The DISK lamp blinks depending on the types of the computer or enclosures.
Changing Status of Physical Device Forcibly The function of changing status of a Physical Device forcibly can be used when you want to change the [Status] of a Physical Device to [Online] or [Failed] forcibly for a maintenance job or another. The function may not be used in normal operation. The function of changing the status of a Physical Device forcibly is available only in the Advanced Mode. The system may not start if you forcibly change the status of the Physical Device used for the system drive.
raidcmd Use "stspd" command. Step 1 Execute "stspd" command with -st option and the following parameters. -c : Number of the RAID Controller containing the Physical Device with its status set to [Online] forcibly -p : Number of the Physical Device with its status set to [Online] forcibly -st : Specify "online" Step 2 Displays the Warning message and the confirmation message. Type "yes" to reply to the confirmation message. Then [Status] of the Physical Device is changed to [Online].

Operation in no failures of Physical Devices If all Physical Devices used by a Logical Drive operates normally (with their [Status] being [Online]), the Logical Drive is in the online status (with its [Status] being [Online]).
Operation when redundancy of Logical Drive degraded or lost due to failure of Physical Device If one or more Physical Devices used by a Logical Drive are failed (with their [Status] being [Failed]) to degraded (one Physical Device of RAID Level 6 is failed) or lost (one Physical Device of RAID Level 1 or 5 is failed, two Physical Devices of RAID Level 6 is failed) the redundancy of the Logical Drive, the Logical Drive is degraded (with its [Status] being [Degraded]).
Operation when failed Physical Device is replaced to recover RAID System Using the RAID System continuously with the redundancy of a Logical Drive remaining degraded may cause the data in the Logical Drive to be lost when another Physical Device is failed further. Recover a Logical Drive of degraded redundancy by Hot Spare or replacement of the failed Physical Device.
Operation when the Logical Drive is offline due to failure of Physical Device If you continue to use the RAID System with lost redundancy of a Logical Drive and another Physical Device is failed further, the redundancy of the Logical Drive is lost completely (two or more Physical Devices of RAID Level 1 or 5 is failed, three or more Physical Devices of RAID Level 6 is failed). The status of a Logical Drive without redundancy is offline (with its [Status] being [Offline]).
