Next, select System Report, and click PCI Cards on left side of the System Information pane. The Driver Installed entry for controller pci1103, 6328 should be Yes 2) RAID Management software installation. In order to configure and manage the HighPoint RAID array, you will need to install the Web RAID Management software (also known as the WebGUI). a. Download and install the RAID Management software from the RS6328 product page: http://www.hptmac.com/series_rs6328-resources.php b. Unzip the package and double-click the HighPoint WebGUI icon to install the WebGUI. You ll be asked to input the system administrator s password to complete installation. c. Running the WebGUI After installation is complete, a WebGUI icon will be displayed on the desktop. 7
d. Double-click this icon to open the WebGUI. The system s default web browser will open a login page. To login, use the default user name: RAID and password: hpt. Warning: Using the WebGUI to create RAID arrays will destroy all pre- existing data on the selected disks. Make sure to backup any important data before using these disks to create arrays. 7. Configuring Storage RAID Arrays 7.1 Configuring RAID Arrays The RS6328 supports multiple RAID levels. The steps below describe how to quickly configure a RAID5 array with 8-bay (8-disk) storage enclosures. Step 1. Verify the physical device status. Click the Physical tab to make sure all of the HDD s are detected. Each drive will be designated as Device 1- N, where N refers to the disk module number. Click the device icon; it will display detailed information about the selected device. If any of the disks are not detected, check the corresponding disk module and make sure the drive is securely installed (see page 6 for more information). 8
Step 2. Verify the Logical Device status. Click the Logical tab to check if any of the disks were previously part of another RAID array. If a RAID configuration is reported, click on Maintenance, displayed toward the right of the Status column and delete the array. Make sure to back up any important data before deleting the array. Step 3. Creating a RAID Array. The following procedure demonstrates how to configure a RAID5 array. A RAID5 array s usable capacity is calculated using the following formula: N-1, multiplied by the capacity of the smallest disk (where N refer to the total number of disks). For more detailed instructions, see section 4.1 Logical: Create Array, on page 20. Note: We recommend using identical hard disk when creating a RAID array. In addition, only use enterprise class RAID edition hard drives. Follow the steps below to create a RAID 5 Array. a. Click the Create Array button on the left panel. b. Select the Array Type (RAID level): RAID 5 c. Select the Initialization Method: Foreground Note: For RAID5, only foreground or background initialization is recommended. The initialization time is dependent on array capacity. The initialization process will zero out all disks so a correct parity can be generated during disk writes. Correct, consistent parity information is essential for the integrity of data when rebuilding RAID 5 arrays. d. Select the Available Disks: Click the Select all button. 9
e. Click the Create button to create the array. f. The following diagram displays RAID5 foreground initialization in progress. 10
g. After the array has been created, it will be displayed under the Logical tab. 7.2 Using the RAID disk with Mac OS X. A newly created RAID Array will be recognized as an empty disk. OS X must initialize it before it can be used. a. Initializing the RAID disk. After a RAID array has been created, OS X will display a pop-up window with options to initialize, Ignore or Eject. Click Initialize to open Disk Utility. 11
b. Erase the Disk Select the RAID volume, and select the Erase tab. Enter a name in the Name: field, and click the Erase button towards the bottom right-hand corner to format the array. Once complete, the RAID array will be ready for use, and will be mounted on the desktop. After the RAID disk is erased, the RAID5 disk volume icon will be found on the desktop and finder as a new disk volume. c. Ejecting the RAID array To eject the RAID array using Mac OS X, select Go from the Desktop, and select Computer. Click on the RAID array (it will be displayed using the name you selected on step 2), and click on File. Select Eject from the drop-down menu to eject the RAID array. Note: The RS6328 supports Thunderbolt power management. While the RS6328 is connected to the host system using the Thunderbolt cable, shutting down the host will automatically power down the RS6328 12
8. Deleting RAID Storage To delete a RAID array: a. Log-in to the WebGUI. b. Switch to the Logical tab. c. Locate the RAID array that you wish to delete. d. Click the Maintenance link to the right of the RAID array. e. Click the Delete button from the Array Maintenance pop up window. f. Confirm the deletion by click OK button. Note: All data on the selected RAID array will be deleted after you confirm this selection. 13
9. RAID Disk Failure Recovery The RS6328 continually monitors the health of each of the disk drives. In the event of a disk failure, an audible alarm will sound. The WebGUI will also report the failed drive and its physical position. NOTE: For redundant RAID arrays (RAID 1, 5, 6, 10 or 50), a drive failure does not result in data loss. However, the array is now in an unprotected state and the failed drive should be replaced as soon as possible to avoid data loss. NOTE: If the storage was configured in RS6328 RAID 6 mode, up to two drives can fail with no loss of data. Replace any failed drive as soon as possible. Follow the steps below to identify and replace a failed drive. a. Launch the WebGUI b. Mute the alarm with the Beeper Mute button. c. The WebGUI will display information like that shown below. An exclamation mark on the RAID array icon indicates that the Status of the array is Critical. The lower portion of the GUI indicates which drive in which disk unit has failed. Note: In this example drive 4 of the RAID 5 Array of has failed. d. Unlock the failed drive s disk module of the storage enclosure and remove the failed drive by gently sliding the drive module out of the enclosure. WARNING: Make absolutely sure that you remove the failed drive indicated by the GUI. Reinstall the disk module immediately if you remove the wrong disk module. 14
e. Replace the failed drive with a new disk module and secure in place. Once the drive has spin up to speed, the WebGUI will indicate that the array is rebuilding (The Status shows Rebuilding and the percentage complete) as shown below. The rebuild time is approximately 2 hours per TB. f. Once the rebuild is complete, the RAID array will return to the Normal status. Your data is now secure. 10. Expanding RAID Storage Capacity Note: Mac OS X cannot support partition expansion DO NOT attempt to use the WebGUI s OCE or ORLM functions with a Mac system. To Expand RAID storage capacity: a. Back up all original data to a separate storage device. b. Delete the current RAID array c. Create a new array using the original and added disks. d. Restore the data from the backup source to the new array. 11.

4. Web RAID Management Software - Logical A. Logical Device Information: It is the logical disk that is connected to the RAID controller and has already been reported to the operating system. Example: Mac OSX Disk Utility B. Physical Device Information: The physical disk attached to the RAID controller. 21
4.1 Logical - Create Array To create an array, users need to provide information to tell utility how to construct this array. This section gives a detail description. The following diagram shows the creation page. A. Array Type Choose the RAID type to create. The HighPoint s RAID controller supports RAID 0, 1, 5, 6, 10, 50 & JBOD. 22
B. Array Name Enter the name for the RAID array. C. Initialization Method Array initialization cleans up each disk to ensure no invalid data exists once the array is in use. This is essential for arrays with parity information (redundant RAID arrays such as RAID 1, 5, 6, 10, 50). When an array is rebuilding, valid parity information is required in order to reconstruct the correct data. There are four initialization options to choose from: 1. Keep Old Data: This is the default option when creating a RAID array. a. This option leaves existing data intact. b. This option does not initialize the array disk. You can use this option when creating RAID arrays with new hard disks (initialization is not generally necessary for new drives, as they contain no data). c. In some cases, this option can be used to recover disabled RAID arrays. 2. Quick Init: The RAID array will be immediately accessible. a. This option will delete all content on the disks. b. This option will not perform disk array initialization. When new HDD s are used this option can be ignored since there is no data on the hard disk. 3. Foreground: The RAID array is not accessible until initialization is completed. a. This option will delete all content on the disks. b. The logical disks will not be reported to the operating system until initialization is complete. This method is faster than Background, and requires far less time to complete. 4. Background: The RAID array is accessible while disk initialization is being performed. a. This option will delete all content on the disks. b. This method will slow the initialization process, but allows the array to be utilized immediately 23
D. Cache Policy Two options are available when creating redundant RAID arrays (1, 5, 6, 10, 50). 1. Write Back Provides higher write performance for redundant RAID arrays. Data is at risk when there is a power failure, system kernel panic and/or the system is not responsive. 2. Write Through Provides superior data protection when there is a power failure. Data is written directly to disk. E. Block Size Block sizes are adjustable from 16K through 1024K, default is 64K F. Number of RAID5 member disks This option is related to creating a RAID 50 array. G. Select All User can select how many disks to construct the array or click this select all to use all HDDs for the array creation. H. Capacity This allows users to define how much disk capacity will be used. If maximum is chosen, then it means use all calculated available disk space. 24
After the array has been created, it will be displayed under Logical Device Information (Below section 4.3). The following information is displayed for each logical device: Name: Type: Capacity: Cache Policy: Block Size: Sector Size: OS Name: Status: Default name of the RAID array Type of RAID array Total capacity of the RAID array Redundant RAID array options for performance or protection RAID array block size RAID array sector size Name of HDD seen in the OS Status of RAID array. Other option include (Normal, Critical, Disable, Rebuilding, Verifying) Array Maintenance: Maintenance provides a selection of general maintenance features and options for the selected array: 1. Diagram 1: Array is in Normal Status 25
2. Diagram 2: Array is in Critical status The arrays current status and RAID level determine which options and features are provided by Maintenance: 1. Delete : Delete the selected RAID array 2. Unplug : Power off the RAID array and remove it. Without using this feature, removing any disk member will trigger the alarm. 3. Verify : This option is only available when RAID is in Normal status. 4. Add : This option is only available when RAID is in Critical status. Click the add disk button to add a new disk in. The following diagram shows how to add a free disk to join the critical array rebuilding. 26
5. Rebuild: Add a disk and rebuild a critical RAID array to normal. The following diagram shows rebuilding array in processing. 6. Change cache Policy: Toggle Between Write Through and Write Back Write Through: Lower write performance because data is written directly to HDD. Data cannot be lost due to power failure or some other circumstance. Write Back: Higher write performance but chances of data lose are greater since data still resides in cache 7. Rename: Rename the array other than the default 4.2 Logical - Spare Pool When creating redundant RAID arrays (1, 5, 6, 10 or 50) a Spare HDD can be configured to automatically help rebuild a degraded redundant RAID. Users can assign any free storage into spare pool. And any disk is in spare pool can be removed as well. The following diagrams show how to operate spare pool. 27
4.3 Logical Logical Device Displays logical devices hosted by the RAID controller. 4.4 Logical - Rescan When hot-plugging a single device or RAID array, the Rescan button prompts the RAID controller to scan for device changes. 4.5 Logical - Beeper Mute This will temporarily disable the internal speaker on the RAID controller. 28
5. Web RAID Management Software - Setting This tab displays various controller settings and options: 5.1 Setting - System A. Enable auto rebuild: If enabled, any new disk attached to the RAID controller will be used to rebuild the critical RAID array. B. Enable Continue Rebuilding on error: Note: The new disk needs to be equal to or larger than the minimum capacity among the remaining disk members of the array. Enabled by default. If disabled, the WebGUI will ignore bad sectors/read failures and allow the rebuild process to continue. Warning: this option should only be enabled in the case of an emergency data inconsistency or data loss may result. Review the Event Log before enabling this option, and check for HDD bad sector events. If bad sectors are found, we recommend first contacting the HDD manufacturer, then technical support, for further advice. C. Enable audible alarm: When a disk goes off-line the beeper on the RAID controller will sound. D. Set Spindown Idle Disk (Minutes): E. Restrict to localhost access: Hard drives can be instructed to spin down when there is no disk activity for a set period of time. You are free to specify the interval from 10 to 240 minutes. This option is used to restrict WebGUI access to the local system and not allowing remote access. F. Set Rebuild Priority: When rebuilding a critical RAID array, there are five rebuilding options to choose from. Each rebuild priority will affect the rebuild completion time. 29
Lowest Lowest Priority when rebuilding arrays. System resources will be assigned to all other tasks first. Low Low Priority. Most of the system s tasks have priority over the rebuild procedure. Medium Medium Priority is the default option system resources are equally distributed between the rebuild procedure and other system tasks. High High Priority the majority of available system resources will be directed towards the rebuild procedure. Highest Highest Priority the RAID controller will utilize all available system resources to rebuild the array. G. Port Number 7402: The listening port number used to log into the WebGUI. 7402 is the default port number. Other port numbers can be used in place of the default as long as they are free. H. Password Setting: The default password hpt can be changed. Note: If the current password is lost or forgotten, you can uninstall and reinstall the Web RAID Management software to restore the default settings. When changing the password, the maximum number of characters allowed is eight. 30
5.2 Setting - Email The HighPoint RAID controller can be configured to send Event Log entries to one or more E-Mail addresses. The email setting has SMTP setting and recipient which users need to configure it. A. Enable Event Check this item to enable Event Notification Notification: B. Server address: This is SMTP mail server address. It can be IP address or SMTP name C. Mail From: This is email address of the sender D. Login Name: The login name of send s email account E. Password: The login password of send s email account F. SMTP Port: This is SMTP port number. The default is 25 for non-ssl SMTP server G. Support SSL: Check this box if using SSL SMTP and change SMTP port to SSL port number. Click Change setting to save new information. H. Support SSL: Setup the recipient s email address I. Name: The name of the recipient J. Event level Check which information that you want to send out for monitoring. The Test check-box is used to verify if email setting is working. 31
6. Web RAID Management Software - Event The Event tab will open the Event View interface. Event View logs all RAID related activity including administrative actions, warnings and hardware failures. There are three options to operate this event log section Clear: Click Clear to remove all current entries from the Event View log. Next: The Event View log can span several pages. Click Next to view past entries. Download: The Event View log can be saved as a text file for reference. 32
7. Web RAID Management Software - SHI (Storage Health Inspector) Storage Health Inspector: SHI will inspect each HDD periodically. If any abnormal status is found, it will be recorded in the Event log. SHI can help to identify problems with HDD s and prevent further damage or data loss. If additional proof of errors is needed, the HDD s can be placed onto the onboard SATA/SAS port and a 3rd party SMART software utility can be run. HDD Temperature Threshold: Setup the HDD temperature threshold to prevent HDD overheating. When the HDD goes beyond the threshold an alert will be triggered. SMART: Schedule SMART attributes for each HDD will be displayed. The following diagram display detail SMART information read out from HDD This allows user to schedule a task to run 33
34
When schedule button is checked, it displays the following configuration page to schedule a task to run. Task List: The Task tab allows you to schedule maintenance sessions for RAID 1, 5, 6, 10 and 50 arrays. User can name each task and specify the frequency, date, hour, minute and second for each session. Regular maintenance is highly recommended for any redundant RAID array, and is essential for maintaining healthy, reliable storage configurations. 35
8. Web RAID Management Software - Recover Recover can help repair RAID arrays that have been assigned the disabled status. This feature helps protect RAID configurations by storing multiple copies of RAID configuration data, which administrators can use to restore a disabled RAID array. Note: Please refer the How-To guide that explains this Recover feature: http://www.highpoint-tech.com/pdf/support/webgui_recover_feature.pdf 36
Appendix B - Web RAID Management ICON Definition List The following table lists the definition of each ICON used by the RAID Management interface (The examples use a RAID 5 array for reference). Icon Description The array status is "Normal". The array has stopped Initializing. Current status is Uninitialized. The array is Initializing : Initializing (Foreground) and Initializing(Background). The array is performing a data consistency checking and its current status is Verifying. The array status is "Critical" - a disk is missing from the RAID array. The array status is "Verifying". This indicates that the array is running a data integrity check. The array status is "Rebuilding". This occurs when the data verification fails or when adding a new disk into the "Critical" array. The array status is "Critical". This indicates that current array needs "rebuild". This icon will also show up on a device in a RAID disk member as needing to "rebuild" its data. The status of the "Array" or "Device" is "Disabled". The array is "Initializing". There are two types of initialization- Foreground and Background. The array OCE/ORLM operation has stopped. This icon means the RAID array is "Uninitialized". On the RAID array either Foreground or Background initialization has stopped (Incomplete). On a disk ( ), it indicates that the disk is not initialized and will need to be initialized for the 1 st time before it can be used with HighPoint RAID card. The device status "Legacy". An existing file system has been created on the HDD. The device is a "Spare". It is used to replace the failed RAID disk member to rebuild automatically. 37
Information. Warning. Error. The array is inconsistent and it needs to rebuild. The current status is Critical. Array disk member diagram is listed below. It shows a RAID-5 disk member is lost and its current status is Critical. Array disk member diagram is listed below. The array is rebuilding and its current status is Rebuilding. Array disk member diagram is listed below. The array is not available. Two scenarios can cause this to happen. First - a lost RAID disk member exceed the minimum required to maintain a RAID level. Second - a disk failed before the initialization or rebuilding process complete. The status is in Disabled. Array disk member diagram is like this: 38
