Team Mode Details of the functions and configurations required for each online mode provided by the DNS-3200 are given below. Adapter Fault Tolerance (AFT) Function: AFT provides automated residue to the network interface card as a fault tolerance. From the two network ports connected to the switch or hub at the same time, one is the primary network for normal team, and the other is the backup and is usually not in the “On” state.
Swap Fault Tolerance (SFT) Function: SFT provides automated residue to the network interface card as a fault tolerance. With the two network ports connected to different switches, one is the primary network for normal team and the other is the backup and is usually not in the “On” state. If the primary online develops problems, the backup network will start and take over the team. Network configuration: 1. Each network port must be connected to a different network switch. 2.
Static Link Aggregation Function: Static Link Aggregation provides network links for increased transmission and receiving flow as well as negative balancing and fault tolerance. The two network ports share all network flows, when one team develops problems, the other one takes over all tasks. Network configuration: 1. The network ports must be connected to the same network switch. 2. All network ports must be online at the same speed. 3.
CHAPTER 4 2 Managing Arrays and Disks This section gives information about Arrays and Disks.
Chapter 4 Managing Arrays and Disks 4.1 RAID Minimum Disk Requirements The following table lists the minimum and maximum number of disks for each RAID level. Table 4.1: Min and Max Disks for RAID levels RAID Level Minimum Number of Disks Maximum Number of Disks Volume 1 32 RAID0 2 32 RAID1 2 2 RAID1n 3 16 RAID10 4 32 RAID10n 6 32 RAID5 3 16 RAID50 6 32 4.2 Understanding Array and Disk States The controller uses states to report the status of arrays and disks.
1. NORMAL The NORMAL state is displayed when everything is functioning correctly. 2. CRITICAL The CRITICAL state is displayed when the array is no longer redundant (fault tolerant) because of one or more disk failures. Arrays can still be read and written to, but the data is no longer protected should another drive fail. 3. OFFLINE The OFFLINE state is displayed when arrays cannot be read or written to because of one or more disk failures.
a rescan of all channels after disconnecting a disk, the state of every array using the missing disk changes from NORMAL to either the CRITICAL or OFFLINE, depending on the array type. Disk States Within the management applications, a disk can be part of one or more arrays and can exist in one of three states: NORMAL, FAILED, or UNKNOWN. In RAIDConsole, these states are displayed in the Disk List area in a column named State. Within the bcadm program, these states are also displayed in a column named State.
Rescanning for Changes in State When using the bcadm program, the disk information that displays when you run a query command is always current. In the RAIDConsole application, however, the information displayed in the Disk List area is the state of the disks when they were last scanned. If you have not performed a rescan, the information being displayed is the state of the disks at boot time.
4.3 Starting and Stopping Tasks Tasks are started when you: • Create a redundant array. • Transform an array. • Restore an array. • Check for consistency on redundant arrays. • Verify a consistency bitmap (check_bitmap) on a redundant array. The only type of task that you can stop without deleting the array is a consistency check (CHECK). The following types of tasks can be displayed for each array: • TRANSFORM The TRANSFORM task is displayed while an array is being transformed.
Note: When a task is in progress and the system is shut down, the RAID driver may hang under certain circumstances. This may occur if arrays exist and a task is in progress, but a drive letter has not been assigned AND an OS partition has not been created on the array. Because neither a drive letter nor partition has been assigned, the OS doesn’t notify the RAID driver that the system is shutting down.
Notes: 1. An array is marked critical or offline if a disk returns failure to an I/O request, or if the SATA or power cable is disconnected. 2. You can assign one or more spares to a redundant array type. 3. Spare assignments do not apply to non-redundant array types. To protect this data, you must first transform the array to a redundant array type (see “Transforming Arrays”). You can then assign spares. 4.4.
Notes: 1. If there is insufficient unused space on the disks in an array, you cannot add a distributed spare without adding an additional disk and transforming to an array with distributed sparing enabled. The distributed spare option uses the equivalent storage of one of the disks in the array. For example: the total capacity of six drives is being used in a RAID5 array, and you have enabled distributed sparing, the capacity of the array is the same as a four-drive RAID0.
To add a distributed spare while transforming an array: 1. On the Array menu, click Transform. 2. Configure the new array. 3. In the Distributed Spare field, click Enabled. To remove a distributed spare: 1. On the Array menu, click Transform. 2. Configure the new array. 3. In the Distributed Spare field, click Disabled. 4.4.3 Using Dedicated Sparing A dedicated spare is a disk that you assign as an alternate disk for a specific array.
Notes: 1. Assigning a dedicated spare does not reserve space on that drive. Therefore, an automatic restore is not guaranteed if a disk fails. If a disk does fail, you must make room on the disk for the fail-over to complete, or you must assign a different disk with enough room. If a dedicated spare is assigned and a drive fails, the restore process starts automatically if there is enough space available on the dedicated spare. 2. You cannot assign a dedicated spare while a task is running on the array. 3.
4.4.4 Using Global Sparing A global spare is a disk that you assign as an alternate disk for multiple arrays instead of associating it with just one. Many arrays can be restored using the global spare disk as long as it is not already part of the array and it has enough space available. Unlike a dedicated spare, this type of spare can be assigned at anytime, even while tasks are running on arrays. Notes: 1. Assigning a disk for use as a global spare does not reserve space on that disk.
CHAPTER 5 2 BIOS Configuration Utility This section explains when and how to use the BIOS Configuration Utility.
Chapter 5 Using the BIOS Configuration Utility 5.1 When to Use the BIOS Configuration Utility The firmware component of the installation kit includes the BIOS Configuration Utility. You must use this utility to: • Create the boot array: If you are not booting off of the array, you do not need to use this utility to create an array, although you can. You can create a non-bootable array in the RAIDConsole management application.
5.2 Color Codes for the BIOS Array Config Utility The following color codes are used to indicate the type or status of information displayed on the screen.
To initialize disks from the BIOS: 1. Turn on your computer to start booting. 2. When prompted, type to access the RAID BIOS Array Configuration Utility. The RAID Array Configuration menu is displayed (see “Color Codes for the BIOS Array Config Utility” in 5.2. 3. Use the arrow keys to select Initialize Disk(s) from the Main menu. 4. Press Enter. 5. Use the arrow keys to highlight a disk, and then press the Insert key to select the disk or choose all selectable disks by pressing A.
Notes: 1. In some circumstances, more than eight arrays are possible and may appear to function properly, but are not supported by Broadcom. 2. For redundant arrays, the creation process does not complete until after the operating system and controller drivers have been installed and you have booted into the operating system context. However, the arrays are immediately available to use for either a boot or data array. 3.
a. In the User Input area, highlight a spare type using the arrow keys. b. If applicable, in the Disks area, highlight the disk(s) to use as a spare and press Insert to select them. c. Press Enter to add the spare disk(s). 5. To select an array size, do one of the following: 6. Use the Page Up/Page Down keys or the arrow keys to select a size, and then press Enter. Note: By default all available space up to 2.199 TB is selected. Or do the following: To create an array that is greater than 2.
Note: For installations of SuSE Linux, a popup appears that says, “A new device was found, do you want to configure it?” If you do not want to see this popup when you create arrays, you can check the “Do not notify me” checkbox. 7. The array is marked Ready for use, and the text at the top of Array Configuration returns to a description of the menu items. 8. When you are finished creating arrays, resume the boot process: a. From the Main menu, highlight Continue to Boot. b. Press Enter.
5.5 Deleting Arrays from the BIOS This option allows you to delete arrays. Caution!: Deleting an array permanently destroys all data that was on the array. You will not be able to undo this action and all data will be lost. To Delete an Array: 1. Highlight Delete Array(s) from the Main menu and press Enter. 2. Do one of the following: a. Highlight each array to delete and press Insert to select it. Or b. Type A to select all arrays for deletion. 3. Press Enter. 4. Press C to continue. 5.
To swap arrays: 1. Highlight Swap Two Arrays in the Main menu, and then press Enter. 2. Use the arrow keys to highlight an array, and then press Insert to select it. 3. Use the arrow keys to highlight another array, and then press Insert to select it. 4. Press Enter to swap the arrays. Figure 5.2: Swap arrays In this example, the RAID10 array was the first array created. However, to boot from the RAID5 array, the arrays were swapped so that the RAID5 array is the first device listed.
5.7 Hiding or Unhiding Arrays from the BIOS The Hide/Unhide array option allows you to hide or Unhide an array or arrays from the operating system. If an array is hidden it will not be visible through INT13 or to the operating system when booted. This is a useful feature for hiding hot backups of the system. Note: You cannot hide a legacy array from the BIOS.
5.8 Viewing Disk Details from the BIOS This option allows you to view details about the disk. When you highlight a disk from the Disk list, the LEDs on the controller or a properly cabled disk enclosure light up to identify that disk. Note: Nothing can be changed from this menu option. It is for information only. To view disk details: 1. From the Main menu, select View Disk Details. 2. Use the arrow keys to choose a disk.
5.9 Viewing Array Details from the BIOS This option allows you to look at the details of the array. Nothing can be changed from this menu option. It is for information only. To view array details: 1. From the Main menu, select View Array Details. 2. Use the arrow keys to choose an array.
5.11 Changing Controller Options from the BIOS Selecting Controller Options allows you to configure whether arrays may be bootable, as well as other aspects of the boot process. The default is to configure an array so that an operating system can boot from the RAID. If an error occurs, an error message is displayed. However, you may be booting from the motherboard IDE or another SCSI device in your system. If this is the case, you may not want to install INT13 (without INT13, DOS cannot see the array).
Figure 5.3: Change controller options 2. Use the arrow keys to select a boot option. Note: 3. By default, all options are turned on. Broadcom recommends that you leave them enabled. Do one of the following: a. If you do not want to boot from an array, highlight Toggle INT13 Installation using the arrow keys, and then press Enter to change the setting to Disabled. (We recommend disabling INT13 only if you want to boot from another device, and leave the rest of the options enabled.) Or b.
Or d. To turn off warnings due to controller configuration errors when booting, highlight Toggle Pause if Error, and then press Enter to change the setting to Disabled. 5.12 Continue Booting from the BIOS After you have created arrays, you can continue booting the system from the point where the RAID BIOS was entered. To resume the boot, highlight Continue to Boot in the Main menu, and then press Enter. No reboot is required.

CHAPTER 6 2 RAID Console Operations This section explains the RAID Console.
Chapter 6 RAID Console Operations 6.1 RAID Console Management For the DNS-3200, RAID management is achieved using the RAID console, of which a brief description on the main functions is given in this chapter. For detailed functions and use of the RAID console, please refer to the RAID Management User Guide in the CD available with this unit. RAID Console RAID console can be started from the icon on the screen.
Notes: 1. The password must consist of at least 6 characters. 2. Passwords are case sensitive. 3. Do remember the password and store in a safe place. If you forget it, you will not be allowed to access the RAID Console. 4. You are given four opportunities to key in the correct password. After the 4th attempt, the program will close and you have to restart.
Disk State Area: Available with state information on each disk, including: • Ctrl Chan: Shows which RAID controller channel the disk is connected to. • State: Disk state, which could be Normal, Failed and Unknown. 1.Normal: Disk online and in normal operation. 2.Failed: RAID controller identifies the disk, but can not read it or write to it. 3.Unknown: New disk or not initialized by RAID controller or freshly formatted. • Type: Type of disk located on the RAID controller (RC_DISK, RC_Legacy, or NEW).
3.Offline: One or more disk failures force the array to go offline, so the system cannot access the array. • Task: Shows the RAID tasks being executed (Transform, Check, Check_Bitmap, Not active, Create, and Restore). • Priority: If any task is being executed, the priority of the task is shown. • Cache: Cache mode of the array in NC = No Cache, R = Read Cache, W = Write Back Cache and RW = Read/Write Cache. • Dst Spare: Showing whether the array is available with distributed spare.
6.1.1 Mirror Split Individual arrays can be made using mirror split as a preset or advanced option. Making splits using advanced options allow the user to indicate clearly which disk to reserve as part of the original array. Mirror split as a preset option A Mirror can be split into individual arrays. One RAID1 array can be split into 2 JBODs and one standard RAID 10 can be split into 2 RAID0 arrays. One standard RAID 1N array or RAID10N array can be split into 1 JBOD and 1 original array.
Mirror split RAID1, RAID1Nm RAID10 or RAID10N as advanced option: 1. Select the array to split using the right button of the mouse. 2. On the array menu, select Mirror > Split > Advanced and the mirror split screen appears (as shown below). 3. Select the disc to stay that belongs to the original array. 4. The split arrays are hidden to avoid access by the operating system. If you do not want to hide the array, uncheck Hide the newly split off array from the OS. 5. Click Commit to begin the split.
6.1.2 Online RAID Level Migration RAID level migration allows you to migrate from a specific level of array to another one. This function allows online RAID level migration or online RAID expansion, even when the system is carrying out I/O. You do not have to restart the system. Together with mirror split, this function provides a complete system backup and repair strategy. Notes: 1. You can not migrate major RAID levels to minor ones.
4. In the disk status area, select the disks that you want to have in the new array. The disks can be the ones included in the RAID to be migrated to. 5. Set the capacity of the migrated array the same as the original array. To expand capacity, just key in the capacity of the new array. 6. Click Commit to begin the split. Note: 7. If you have set the wrong migration configuration, you will not be allowed to press the Commit key.

Use the advanced option to split RAID1N into 2 RAID1 arrays. At this time, Array 3 (as shown below) appears in the split array list.
2. The split backup system array (Array 3) is renamed, with a date for identification. Right-click Array 3 and select Name on the array list. The name window appears. Key in the name you want and then press Change Name.
7.1.2 Operating System Swap When the primary operating system is damaged and can't start, the hidden backup operating system (Array 3) can be used to start the system. The RAID BIOS must be used to swap to the hidden backup OS. 1. Restart the unit and press to enter the RAID BIOS. 2. In the upper left corner you can see the complete list of arrays (as shown below). Array 3 has just undergone a mirror split. The blue indicates that it is a hidden array.
3. Use the Insert key to decide on the 2 arrays to swap. The selected arrays will be shown in green (as shown below).
4. After the selection, press Enter to execute the swap. After the swap, Array 3 (Backup OS) turns into Array 1 (as shown below).
5. Finally, change the hidden Backup OS to unhidden, and Primary OS to hidden. Select Hide/Unhide Array(s). Use the Insert key to select Standby, Backup OS and press Enter to execute. After canceling the hide, the Backup OS array is shown in white and Primary OS in blue as shown below. Select Continue to boot the system.
7.1.3 Operating System Repair After turning on the system with the backup operating system, the damaged operating system (Array 3) must be repaired, so it can be the backup operating system. 1. Open the RAID Console and right-click on the Primary OS (Array 3). Then click Delete and select OK to delete the damaged Primary OS array. 2. Change the current Backup OS array name to “Primary OS” for easy identification. 3.
4. After RAID online migration is finished, use Mirror Split on the Primary OS (Array 1) to split it into 2 x RAID 1 arrays. The split array is shown as “Array 3 Primary OS.” 5. Rename Array 3 to Backup OS with a date for easy identification. The array is then the new backup operating system array.
Notes: 1. When it is assured that the system is functioning correctly after undergoing major changes (e.g. software installation, hardware modification), the backup operating system should be updated (by deleting the backup operating system array, migrating the primary operating system array as RAID1N and splitting the primary array). This assures that the backup operating system is always up-to-date. 2.
