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.

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, and 2. Connecting with more than one unused Physical Device. 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.

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 server. 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.
Step 2 After the Consistency Check is started, the raidcmd terminates normally. Check the execution status of the Consistency Check by using "oplist" command. Executing Consistency Check for arbitrary Logical Drive You can register the task to schedule the Consistency Check using the Task Scheduler on Windows or cron on Linux or VMware ESX.
Executing Consistency Check for all Logical Drives for a RAID Controller which not support Patrol Read or of which the Patrol Read is disabled. Use "ccs" command of the raidcmd. Stopping Consistency Check You can stop Consistency Check being executed on the way. The procedure of stopping Consistency Check is described below. RAID Viewer 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.
Setting Consistency Check Priority You can set the priority at which Consistency Check is executed in the server. The procedure of setting the Consistency Check Priority is described below. Setting Consistency Check Priority are available only in the Advanced Mode. RAID Viewer Step 1 Start the RAID Viewer. Click the RAID Controller on the Tree View. Then click [Properties] on the [File] menu. Step 2 Click the [Options] tab in the [RAID Controller Properties] dialog box.
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 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 server. 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 range of change differs depending on the type of the RAID Controller. RAID Controller Changed cache Range of change Onboard RAID Controller (LSI Embedded MegaRAID) Hard Disk Drive All the Logical Drives in a single Disk Array. Option and Internal RAID Controller (N8103-128/G128/134/135) RAID Controller All the Logical Drives in a single 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.
raidcmd Step 1 Execute "rebuild" command with -op option and the defined parameters. 1 > raidcmd rebuild -c=1 -p=e252s4 -op=start > > raidcmd oplist RAID Controller #1 PD e252s4 : Rebuild (Running 0%) > 2 -c : Number of the RAID Controller containing the Physical Device for which Rebuild is executed -p : Number of the Physical Device for which Rebuild is executed -op : Specify "start" to start Rebuild Ex.
Checking Result of Executing Rebuild You can find the result of executing Rebuild by checking the Tree View, the property of the Physical Device and the RAID Log of the Universal RAID Utility. If Rebuild succeeds, the icon of the Physical Device subject to the Rebuild changes to [Online] on the Tree View. In addition, the [Status] in the Property tab of the Physical Device is set to [Online]. When detects something problem, Universal RAID Utility records the log in the RAID Log.
Reducing the power consumption of the Physical Device The HDD Power Saving is the function to spin down the Physical Device that is not in use. The HDD Power Saving reduces the power consumption of the System by spinning down the Physical Device. Set the Power Saving in each RAID Controllers. You can see which type of the Physical Device is available for the HDD Power Saving function in the table below.
raidcmd Step 1 Execute "optctrl" command with -psd option and the defined parameters. 2 -c : Number of RAID Controller for which Power Saving Device is set. -psd : Select none or hotspare to change the Power Saving Device. Ex) Changes value of HDD Power Saving (Hot Spare) to "enable" (RAID Controller Number is 1) raidcmd optctrl -c=1 -psd=hotspare Step 2 Checking the execution result by using "property" command. The following parameter of RAID Controller is changed.
raidcmd Step 1 Execute the "optctrl" command with -dst option and the defined parameters. -c : Number of RAID Controller for which Device Standby Time is set. -dst : Select 0.5, 1, 2, 4, or 8 hours to change the Device Standby Time. Ex. Changes the value of Device Standby Time to "2hours" (RAID Controller Number is 1). raidcmd optctrl -c=1 -dst=2 Step 2 The property of the RAID Controller changes after the setting has been changed successfully.
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 server or enclosure. In actual, locate turns on the DISK lamp on the server or enclosure in which the specified Physical Device is installed. (The DISK lamp blinks depending on the types of the server 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 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" Ex. Make the Physical Device (RAID Controller Number: 1 and Physical Device Number: e252s4) Online forcibly. raidcmd stspd -c=1 -p=e252s4 -st=online Step 2 Displays the Warning message and the confirmation message.
raidcmd 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 Failed forcibly -p : Number of the Physical Device with its status set to Failed forcibly -st : Specify "offline" Ex. Set the Physical Device (RAID Controller number: 1 and Physical Device number: e252s4) to Failed. raidcmd stspd -c=1 -p=e252s4 -st=offline Step 2 Displays the Warning message and the confirmation message.
Refreshing the battery of the RAID Controller The Refresh Battery is a function to refresh the battery connected to the RAID Controller. The function restores the battery degraded due to charge and discharge. Universal RAID Utility provides the function to manually execute the battery refreshing. The function can be done for each RAID Controller. You can use a Windows task scheduler to do a regular battery refreshing. The Refresh Battery is not supported for some RAID Controllers.
raidcmd Step 1 Execute "refresh" command using the following parameter. -c : Number of RAID Controller for which Refresh Battery is set. > raidcmd refresh -c=2 Refresh the battery. 1 Do you continue ? [yes(y) or no(n)] :yes > 2 Ex) Refresh the battery (RAID Controller number: 2). raidcmd refresh –c=2 Step 2 Execute the "refresh" command to display the confirmation message. Enter [Yes] to execute battery refreshing. Enter [No] to cancel battery refreshing.

raidcmd Step 1 Execute raidcmd without command to check the component where a failure occurs. Step 2 Execute "sbuzzer" command with the following parameter. 2 > raidcmd sbuzzer -c=1 > -c : Number of the RAID Controller for which Buzzer is stopped Ex.
ESMPRO User Group is the name group for the management of NEC ESMPRO Manager (specified it when installed NEC ESMPRO Manager). If you forget the name of group, see the following registry key.
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]).
