Openfiler provides key features such as iSCSI target megaraid virtualization, Fibre Channel target support, block level replication and High Availability that are the mainstay of any business critical storage environment.
Openfiler addresses all the key data storage concerns:. In this case, the stripe size is 64 KB and the strip size is 16 KB. A larger strip size produces higher read performance. If your server regularly windoas random read requests, choose a qindows strip size. This is the default.
This option speeds up reads for sequential data but there is little improvement when accessing random data. This setting is recommended in Standard mode. If you do not choose this option, the controller firmware automatically switches to Writethrough mode if it detects a bad or missing BBU.
Data is transferred to the cache and the host concurrently. If the same data block is read again, it comes from the cache memory. The IO Policy applies to reads on a specific virtual drive. It does not affect the read-ahead cache. You can specify a smaller size if you want to create other virtual drives storage the same drive download.
Step 8 Click Accept to accept the changes to the virtual drive definitions. Step 9 After you finish the virtual drive definitions, click Next. The Configuration Preview window appears. Step 10 Check the virtual drive configuration in the Configuration Preview window and choose one of the following:. Step 11 Click Yes at the prompt to save the configuration.

Step 5 Choose the drive group created in Step 4and press and hold Ctrl while choosing more ready drives in the Drives pane to create a second RAID drive group. Note RAID 00 supports a maximum windows eight spans with a maximum of 32 drives per span.
Note RAID 10 supports a maximum of eight spans with a maximum of 32 drives per span. You must use an even number of drives in each RAID 10 drive group in the span. Step 7 From the Encryption drop-down list, choose an encryption option. Step 9 Repeat Step 4 through Step 6 until you have chosen all the drives you want for the drive groups.
Step 10 After you finish adding drives to the Drive Groups pane, choose each drive group, and click Accept DG after each drive group choice. The Span Definition window appears. This window shows the drive group holes that you can choose to add to the Span pane.
The drive group manager chose appears in the Span pane. Step 14 Repeat Step 12 and Step 13 windows you have chosen all of the drive groups that you need. Step 16 Press and hold Ctrl to choose the drive group in the Configuration pane, and then choose the virtual drive options storage the drop-down lists in the left pane the default values are shown :.
This speeds up reads for sequential data but there is little improvement when accessing random data. Step 17 Click Accept to accept the changes to the virtual drive definitions. Step 18 After you finish the virtual drive doenload, click Next. Step etorage Check the virtual drive configuration in the Configuration Preview window and choose one of the following:.
Step 20 Click Yes at the prompt to save the configuration. If your computer system has manager LSI SAS controllers, you can view information for a different controller by clicking Controller Selection in the main window. When the Controller Selection window appears, vownload the megaraid you want from the list.
To view the properties of the current controller, follow these steps:. There are three Controller Properties windows. The information in the first window is read-only and cannot be dwnload directly.
Supported Storage Controllers and Cables
The window downloac the number of virtual drives that are already defined on this controller and the number of drives connected to the controller. Step 2 Click Next to view the second Controller Properties window. Step 3 Click Next to view the third Controller Properties window.
Table describes the entries and options listed in the second and third Controller Properties windows. LSI recommends that you leave these options at their default settings to achieve the best performance, unless you have a specific reason for changing them. Step 4 If you make changes mansger the options on these windows, click Submit to register them.
If you change your mind, click Reset to return the options to their default values. Table Controller Properties Menu Options. Indicates whether the chosen controller has a BBU. If present, you can click Present to view information about the BBU. For more information, see Viewing and Changing Device Properties.
The default is No. Chooses the rebuild rate for drives connected to the chosen controller. The default is 30 percent. The rebuild rate is the percentage of system resources dedicated to rebuilding a failed drive.

The higher the number, the more system resources are devoted to a rebuild. Chooses the amount of system resources dedicated to background initialization of virtual drives connected to the chosen storage. Chooses the amount of system resources dedicated to consistency checks of virtual drives connected to the chosen controller.
Chooses the amount of system resources dedicated to reconstruction of drives connected to the chosen controller. Enables download disables the BIOS for the chosen controller. The default is Enabled. If the boot device is on the chosen controller, the BIOS must be enabled. Otherwise, the BIOS windows be disabled or it might not be possible to use a boot device elsewhere.
Native Command Queuing NCQ gives an individual drive the ability to optimize the order in which it executes the read and write commands. Drive coercion is a tool for forcing drives of varying capacities manager the same size so they can be used in a drive group. The default is None. The number you choose depends on how much the drives from various vendors vary in their actual size.
LSI recommends that you use the 1-GB coercion megaraid option. The default is seconds 5 minutes. Enables, disables, or silences the onboard alarm tone generator on the controller. The default is Disabled. Chooses the rate for patrol reads for drives connected to the chosen controller.
The patrol read rate is the percentage of system resources dedicated to running a patrol read. Controls the interval in seconds at which the contents of the onboard data cache are flushed. The default is 4 seconds.
Controls the number of majager that spin up simultaneously. The default is 2 drives. Controls the interval in seconds between download spinup of drives connected to this manager. The delay prevents a drain on the system power supply storage would occur if all drives spun up at the same time.
The default is 12 seconds. When enabled, this option stops the boot process when the controller BIOS encounters an error during mebaraid. Controls the interval in seconds between the spindown of drives connected to this controller. The default is 30 minutes.
When enabled, this option stops a consistency check when the megaraid BIOS encounters an error. Maintains the history of all drive failures. Indicates whether the option to schedule the date and time for a consistency check is supported. The Virtual Drive window displays the following information:. Windows from the following options and click Go to perform an operation:.
For more information, see Deleting a Virtual Drive. A fast initialization quickly sownload zeroes to the first and last MB regions of the new virtual drive and completes the initialization in the background. A slow initialization is not complete until the mabager virtual drive has been initialized with zeroes.

It is seldom necessary to use this option, because the virtual drive was already initialized when you created it. For more information, see Using Manual Configuration. This option is not available for RAID 0 virtual drives. In addition, you can add drives to the virtual drive to increase the capacity.
Note Drives can be added to a drive group only when there is a single virtual drive present on the drive group. If there are multiple virtual drives present on the drive group, the option to add an extra disk is not available. See Expanding a Virtual Drive for the procedure you can use to expand a virtual drive.
The Physical Drive window displays the properties of a chosen drive and then enables you to perform operations on the drive. To view drive properties and perform subsequent operations, follow these steps:. Step 1 To access the Physical Drive window, choose one of the following options:.
Step 2 Click Propertiesand click Go. The drive properties window for the chosen drive megaraid. The drive properties are view-only and include the state of the drive. Step 3 Download the drive state is Onlinechoose one of the following operations and click Go :. Note If you force offline a good drive that is part of a redundant drive group with a hot spare, the drive rebuilds to the hot spare drive.
The drive you forced offline goes into the Unconfigured Bad state. Step 4 If the drive state is Unconfigured Goodchoose one of the four following operations and click Go :. The icon for the dedicated hot spare displays under its associated virtual drive. The drive number, drive state, drive capacity, and drive manufacturer display.
If there are drive failures present on a split backplane configuration, then the hot spare will be used first on the backplane side that it resides in. The Prepare for Removal feature is different from spinning a drive down into powersave mode, because it also involves flagging the drive as ready to remove.
Therefore, if you choose to prepare a drive for removal, Ready to Remove displays in the device tree for that drive, instead of Powersave. The first Controller Information window appears. The second Controller Properties window appears. Step 3 Click Present in the Storage Backup field. The Battery Module window appears.
This window contains the following information:. Most of the Battery Module properties are view-only and are self-explanatory. In the lower right corner of the window are the auto learn options. A learning cycle is a battery calibration operation performed by the controller periodically to determine the condition of megaraid battery.
Windlws can change the learn delay interval the length of time between automatic learning cycles and the auto learn mode. Note LSI recommends leaving the learn delay interval and the auto learn mode at their default settings. Mebaraid section includes information about maintaining and managing storage configurations. You can increase the size of a virtual drive to occupy the remaining capacity in a drive group.
Note You can expand a virtual drive only if it is the only virtual drive present in the drive group. When multiple virtual drives are present in a drive group, you cannot expand the virtual drives. In addition, you can add drives to the virtual drive to manager capacity.
When multiple virtual drives present on the drive group, the option to add an extra disk is not available. The Virtual Drive window appears. Step 2 Choose the Expand radio button and click Go. The Manager Virtual Drive window appears. Step 3 Enter the managee of the available capacity that you want the virtual drive to use.
For example, if GB maager is available and you want to increase the size of the virtual drive by 30 GB, choose 30 percent. Step 4 Windows Calculate to determine the capacity of the virtual drive after expansion. Step 5 Click Ok. The virtual drive expands by the chosen percentage of the available capacity.
You should periodically run a consistency check on fault-tolerant virtual drives. Step 2 Click Virtual Drives. Note If the WebBIOS CU finds a difference between the data and the parity value on the redundant drive group, it assumes that the data is accurate and automatically corrects the parity value.
Be sure to back up the data before running a consistency check if you think the data might be corrupted. MegaRAID Recovery, also known as Snapshot, offers a simplified way to recover data and provides automatic protection megaeaid the boot volume. You can use the Recovery manater to storage a snapshot of a volume and to restore download volume or file.
Snapshot functionality allows you to capture data changes to the volume, and, if data is deleted accidentally or maliciously, you can restore the data from storge view or roll back to a snapshot at windows previous point-in-time PiT. Each Recovery PiT volume snapshot is typically a fraction of the original volume size, because it tracks only the changes that are made to a volume after the PiT is created.
The disk space for PiTs is reserved in the Snapshot Repository virtual drive, and the PiT is expanded in small increments as new data is written to the volume. Multiple PiTs of each volume can be retained online, enabling frequent snapshots to be stored in a space-efficient manner. Three primary scenarios in which to use the Recovery feature are as follows:.
Restore the missing or deleted files restore from view. Discover that files are missing or deleted. A Snapshot view contains the content from the Point-in-Time at which the snapshot was made. Drag and drop the missing file from the Snapshot view back into windows online storage volume that was the source of the Snapshot.
If there are corrupt operating system files wimdows a volume, roll back the volume to a previous state:. Select the most recent snapshot that does not contain the corrupted or malicious file to roll back to. Select the most recent PiT snapshot to roll back donwload. The system automatically rolls back to its previous state storage on the selected PiT snapshot.
When the application is offline, take a snapshot of the application volume. Install each patch individually and test for any new defects that might have been introduced. Managr a snapshot after you test each patch and determine that it manager clean. If a defect is introduced, roll back to the previous installation and bypass the installation of download defective patch.
Note If the volume is still damaged, continue to select from the next most current PiT snapshot to the oldest. After you enable Recovery, you create two virtual drives: one as a Snapshot Base or source and the other as a Snapshot Repository. The Snapshot Base virtual drive contains the data that megaraif stored in the repository virtual drive.
You can delete any virtual drive on the controller if you want to reuse that space for a new virtual drive. If multiple virtual drives are defined on a single drive group, you can delete a virtual drive without deleting the whole drive group. Step 2 Megaraid the Delete radio button in the Operations area, and click Go.
Step 3 When the message appears, confirm that atorage want to delete the virtual drive.

A foreign configuration is mnaager storage configuration that already exists on a set of drives that you megaraiv in a server. To migrate an existing array from one server to another, as in the case of a server replacement, the new server must have the same controller type as the server on which the array was initially created.
In addition, if one or more drives are removed from a configuration, by a cable pull or drive removal, for example, the configuration on those drives is considered a foreign configuration by the RAID controller. Drives that have existing configurations, including foreign configurations, do not appear. To use drives with existing configurations, you must first clear the configuration on those drives.
Megarai 1 In the Foreign Configuration window, click the Select Configuration drop-down list to show the configurations. Step 2 Choose a configuration or All Configurations. Step 3 To preview or clear a foreign configuration, do one of the following:. If you click Cancelit cancels the importation megarair preview of the foreign configuration.
The right pane shows the virtual drive properties of the foreign configuration. The left pane shows the drives in the foreign configuration.
