1.1.3 System Protection

The DNS-3200 is designed for network file services and meets industrial standards, such as hardware RAID and Web interface remote management for successful upgrading and increased stability and reliability of the system.

To aid system reliability, the DNS-3200 operating system is configured with RAID 1N technology when released from the factory, where the first 10 GB of hard disk space is kept for Mirroring and the operating system is installed in that area. If several hard disks experience problems, the user may still turn on the operating system. The user may also use the Mirror Split to divide the operating system that has been installed, enabling a dual operating system mode. If the primary operating system is damaged and not available, the backup system will boot the unit for service while the damaged operating system can be repaired.

Note: For details on installation of the dual operating

system and repairs of the operating system, please refer to System Protection and Repairs.

As for protection of the data split area, the DNS-3200 is available with a logical region of the hard disk excluded from the space for the operating system. The operating system uses RAID 5 technology when released

3 Chapter 1

from the factory. In that mode, when a hard disk is damaged, the data remains accessible as usual.

Each and every DNS-3200 is available with a SATA hot plug hard disk when released from the factory plus 2 logically split areas. Data in the split areas are available in the following tables and figures.

Note: Default layouts may vary depending on the num-

ber of hard disks.

Team M ode

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. If the primary online adapter card develops a problem, the backup network will start and take over the team.

Network configuration:

1. The network port must be connected to the same network switch.

2. The switch must have the Spanning Tree Protocol (STP) in the “Off” state.

3. All switches are available for support.

DNS-3200 User’s Manual 36

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. The switch must have the Spanning Tree Protocol (STP) in “On” state.

Adaptive Load Balancing (ALB) Function: ALB provides load balancing and fault tolerance to the net-

work flow and uses the software to analyze the transmission load on each interface card. For the two network ports sharing the load balancing of the transmission load and received flow load balancing of the IP protocol, if one team develops problems, the other team will take over the task.

Network configuration:

1. The network ports must be connected to the same network switch.

2. All switches must be able to support ALB.

Note: ALB does not balance non-routable communica-

tion protocols, such as NetBEUI and some other IPX* flows.

37 Chapter 3

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. Use only network switches capable of Link Aggregation:

• Use Cisco FEC or GEC network switches with the PAgP proto-

col.

• Intel network switches

• All network switches supporting static 802.3ad.

Dynamic Link Aggregation Function: Dynamic Link Aggregation provides network links for

increased bandwidth as well as negative balancing and fault tolerance. Two network ports share all network flows, when one team develops a problem, 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 different speeds.

3. The online switches must be fully compatible with the IEEE

802.3ad standard.

4.2 Understanding Array and Disk States

The controller uses states to report the status of arrays and disks. To ensure the health of your data, it is important to understand what each array and disk state means as well as what causes them to change.

Array States

Within the management applications, an array is a logical device that can exist in one of three states: NORMAL, CRITICAL, or OFFLINE. In RAIDConsole, these states are shown in the Array List area in a column named State. Within the bcadm program, these states also shown in the column named State. The states are defined as follows:

Whether an array is marked as CRITICAL or OFFLINE depends on the type of array and how many disks within the array have failed. Note the following changes in state:

DNS-3200 User’s Manual 40

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.

• For RAID1 and RAID5 (redundant arrays), the CRITICAL state is dis-

played when a single disk fails.

• For RAID1n, RAID10, RAID10n, or RAID50 (array types with multi-

ple redundancies), the CRITICAL state is displayed if a single disk fails in any one of those sets.

• For Volume and RAID0, the OFFLINE state is displayed when a single

disk fails.

• For RAID1 and RAID5 (redundant arrays), the OFFLINE state is dis-

played when two or more disks fail.

• For RAID1n, RAID10, RAID10n (array types with multiple redundan-

cies), the OFFLINE state is displayed if all disks in a set fail.

• For RAID50 (an array type with multiple redundancies), the OFFLINE

state is displayed if two or more disks fail within the same set. For example, RAID50 is a stripe of RAID5 sets. If a RAID50 set contains three RAID5 sets, each RAID5 set can have up to one disk failure and the RAID50 array state shows as CRITICAL. If a fourth disk fails, the state of the RAID50 array changes to OFFLINE. If two drives fail on one of the RAID5 sets, the state of the RAID50 array changes to OFFLINE.

More than one array can be created using the same set of disks. If you disconnect a disk that belongs to more than one array, only the arrays that try to access the disk and receive I/O errors report the failure. For example: you have two arrays, both RAID5 sets, and both use disk 4. If a system being used by array 1 receives an I/O error when trying to communicate with disk 4, the state of array 1 will change to CRITICAL. However, the state of array 2 using disk 4 will not change to CRITICAL until an I/O error is reported. If systems using array 1 are not communicating with the failed disk, the state of array 1 still displays as NORMAL. If you perform

41 Chapter 4

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. The states are defined as follows:

• NORMAL The NORMAL state is displayed when the disk is con-

nected, functioning correctly, and the controller can communicate with it.

• FAILED The FAILED state is displayed when the controller can rec-

ognize the disk, but cannot read or write to it.

• UNKNOWN The UNKNOWN state is displayed when the disk is new

and has not been initialized, or is in a format unrecognizable by the controller.

If a disk fails, its state in the Disk List is displayed as FAILED. However, if the system tries to communicate with a disk that has been physically disconnected, the disk shows as FAILED in the Array List window but still appears in the Disk List as NORMAL until a rescan is performed. After you have rescanned the SATA channels for information, the disconnected disk disappears from the Disk List.

DNS-3200 User’s Manual 42

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.

Every time you connect or disconnect a disk while online, a message asking if you want to perform a rescan (of all SATA channels) appears. If you choose Ye s , the information in both the Array List and the Disk List is updated. However, this view may show arrays as being in a CRITICAL or OFFLINE state if not all disks have been installed or removed.

Although it is highly recommend that you shut down the system before you add or remove disks, you may also be able to add or remove disks while online if your system supports that feature. Because of this feature, RAIDConsole does not automatically perform a rescan when it detects that a disk has been added or removed. For example, if you want to hotswap a RAID5 set with six disks into a new system, do not perform a rescan until all six disks have been connected. Otherwise, any arrays associated with the disks that are not yet connected change state to either CRITICAL or OFFLINE. If the state of your RAID5 set changes to OFFLINE, you will lose your data. This feature can also result in the state of a disk being reported differently in the Array View and the Disk List. A disk within an array can have a state of FAILED in the Array tree view while at the same time it can show a state of NORMAL in the Disk List.

43 Chapter 4

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.

• CREATE The CREATE task is displayed while an array is being cre-

ated.

• CHECK The CHECK task is for redundant type arrays only. This task

is displayed while verifying that the parity (RAID5) or mirror drive consistency is correct.

• RESTORE The RESTORE task is displayed while an array is being

restored.

• CHECK_BITMAP The CHECK_BITMAP task is displayed while

verifying that the parity on a RAID5 set, or the mirror halves on a RAID1/10 set, are consistent. This action is performed automatically if your system crashes.

• NOT_ACTIVE The NOT_ACTIVE task is displayed when no other

tasks are being performed.

DNS-3200 User’s Manual 44

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. If this condition occurs, the system can be reset, the OS will start, and the RAID process will also restart.

4.4 Working with Spares

4.4.1 About Sparing Options

The DNS-3200 Series RAID controller supports three sparing options:

• Distributed A patent-pending sparing option comprised of reserved

space on each disk in an array

• Dedicated A spare disk assigned to a specific, redundant array

• Global A spare disk that is shared by multiple arrays

Spares are restored in the following order:

• Dedicated

• Distributed

• Global

45 Chapter 4

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.

4.4.2 Using Distributed Sparing

The distributed sparing feature reserves space on each drive in an array. This space is used when the data from a failed drive is being regenerated during a restore task. Whereas other methods of sparing (such as dedicated spares) provide the same level of protection, distributed sparing provides better performance because all drives are active in an array and are not sitting idle, as is the case with dedicated spares. Another advantage of distributed spares is that because all drives are active, a drive cannot fail and go unnoticed, as is the case with dedicated or global spares. This is because with distributed sparing, each array has its own dedicated fail-over spaces.

This averts the potential problem of having insufficient space to start a failover on the single disk that has been assigned as a spare.

A distributed spare is assigned at the time an array is created or transformed. Distributed spares are valid only for RAID5 (four or more drives), RAID50 (four or more drives per RAID5 set), and RAID10 and RAID10n (six or more drives).

This spare type is the most protective because space is allocated when the array is created. Like a dedicated spare, this spare type is assigned to a specific array. If you initially created an array without a distributed spare, you must transform the array to add a distributed spare. This is because a distributed spare can be assigned only when an array is being created or transformed.

DNS-3200 User’s Manual 46

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. The capacity of one disk is lost to the RAID5 parity data, and the capacity of another disk is lost to the distributed sparing option.

2. See “About Sparing Options”.

To add a distributed spare while creating an array:

1. On the Array menu, click Create.

2. Configure the array.

3. In the Distributed Spare field, click Enabled.

47 Chapter 4

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. Should a disk fail in that array, the alternate disk is used to replace the failed disk and the array is rebuilt. A dedicated spare can be assigned to any redundant array type, and up to four spares can be assigned to an array.

DNS-3200 User’s Manual 48

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. When you assign a dedicated spare either while creating or transforming an array, the first drive you select to create the array is assigned by default as the dedicated spare.

4. When you add a dedicated spare after the array has been created, you can select which disk to use as the spare.

5. For more information see “About Sparing Options”.

49 Chapter 4

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. Therefore, an automatic restore is not guaranteed if a drive fails. If there is not enough disk space on the global spare, you must either make room for the failover to complete or assign a different disk with enough room as the spare. However, if there is enough space available on the global spare and a drive failure occurs, the restore process starts automatically.

2. For more information see “About Sparing Options”

• Continue Booting from the BIOS

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.

• Swap in a copy of the boot array: In RAIDConsole, you can make a copy of your boot array by mirroring and then splitting the array. By default it is hidden from the operating system. If you were to lose the boot array, you can use the BIOS Configuration utility to Unhide the copy and swap it into the first position in the Arrays list.

• Initialize a new disk: When you are adding a new disk you can initialize it from the BIOS.

Notes: 1. The first device in the Arrays list is the boota-

ble array. You can only boot from the first device in the list.

2. Until the BIOS loads, the LEDs are not indicative of disk connectivity.

To enter the BIOS Configuration Utility

When booting the system, press CTRL+R when the BIOS banner is displayed. You have up to three seconds to enter the BIOS using this key combination.

DNS-3200 User’s Manual 52

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.

• White text Available option or informational text

• Yellow highlighting Current option on which you may choose to

take action

• Green text Item has been selected

• Light blue text Item is not available for selection

• Yellow text Informational text, describes an option

• Magenta text Spare options and boot options

• Red text Failed drive or other warning to user. For

example, informational text may be red if the option is not available.

5.3 Initializing Disks from the BIOS

Before using new disks they must be initialized and at least the boot array must be created using the RAIDCore BIOS Array Configuration Utility.

Initialization writes the configuration information to disk. The BIOS utility can be used to create and manage arrays so that an operating system can be installed on an array. The system is then booted from this array.

Notes: 1. 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.

2. If you want to boot from another controller within your system, you may need to disable INT13 in the BIOS. See “Changing Controller Options from the BIOS”.

3. For more information see “Color Codes for the BIOS Array Config Utility” in 5.2.

53 Chapter 5

To initialize disks from the BIOS:

1. Turn on your computer to start booting.

2. When prompted, type <CTRL-R> 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

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.

Note: You can select multiple disks; there is no need to

initialize one disk at a time.

5.4 Creating Arrays from the BIOS

After your disks are initialized, you can create arrays. You can create a maximum of eight arrays from the BIOS. See “Understanding Arrays” if you have not yet decided what type of arrays you need.

DNS-3200 User’s Manual 54

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. Array numbers are valid only for a given boot, and may be different in the BIOS and drivers. If a permanent label is required, use the labeling feature.

4. 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.

5. At any point in the following procedure, you can return to a prior screen by pressing ESC.

6. See see “Color Codes for the BIOS Array Config Utility” in 5.2.

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. No reboot is required.

Figure 5.1: Create an array

In the example above, a 4-drive RAID5 array has been configured.

57 Chapter 5

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.

b. Type A to select all arrays for deletion.

3. Press Enter.

4. Press C to continue.

5.6 Swapping Arrays from the BIOS

Using the Swap Two Arrays option, you can reorder arrays.

Notes: 1. If you create more than one array, you can

install the operating system to any of them. However, a small amount of boot information is always written to a disk in the first array on your array list regardless of which array you install the operating system on. If anything happens to that disk in Array 1, you will not be able to boot. Broadcom recommends installing on a redundant array type — such as RAID1 or RAID5 — and then swapping that array into the first position if it is not already Array 1.

2. This swap feature is only available from the BIOS.

DNS-3200 User’s Manual 58

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.

59 Chapter 5

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.

You can hide a legacy array from the operating system (using RAIDConsole), if you have not booted off the legacy array and another non-legacy disk is attached to the controller.

To hide or Unhide an array:

1. Select the Hide/Unhide option.

2. Use the arrow keys to highlight the array to be hidden or unhidden.

3. Press the Insert to select an array.

4. Press Enter to commit the selection.

The hidden array turns blue in the BIOS Configuration Utility and the status of the array displays as Hidden.

DNS-3200 User’s Manual 60

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.

The details of the disk are displayed in the Information field across the top, and include the following data:

• Disk Number

• Controller Number

• Channel Number

• Disk Size

• New/Legacy/Empty/InArray

• Free Space

• Disk Model Number

61 Chapter 5

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.

The full details of the array are displayed in both the Information field across the top, and include the following data:

• Array Number

• Type

• Size

• State

• Name

• Cache setting

• DOS size

Note: The Disks list shows the disks in the array as

selected (green).

5.10 Rescanning All Channels from the BIOS

This option allows you to rescan all channels to detect new or removed disks and arrays.

To perform a rescan, select Rescan All Channels from the Main menu. The activity indicator in the Information field spins while the disks are being polled.

DNS-3200 User’s Manual 62

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).

Note: If you configure Boot Mode to install INT13 and

to never display an error message, you will not know during the boot process if an array is degraded or if other problems have occurred.

This menu also sets whether you want the boot process to pause when an error occurs. When the Pause feature is enabled and an array goes critical or offline, or there is a controller configuration error, the boot process stops and you must press Enter to continue booting. This gives you time to view the error message on the screen. If the Pause feature is disabled, the error message is displayed briefly, but the system continues to boot.

To select a boot option:

1. From the Main menu, select Controller Options. The Controller

Options area is displayed in the BIOS Array Configuration Utility window as shown below. The current settings display in

magenta text above the white selectable options.

63 Chapter 5

Figure 5.3: Change controller options

2. Use the arrow keys to select a boot option.

Note: By default, all options are turned on. Broadcom

recommends that you leave them enabled.

3. 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.)

b. To turn off warnings due to critical arrays when booting, high-

light Toggle Pause if Critical, and then press Enter to change the setting to Disabled.

c. To turn off warnings due to offline arrays when booting, high-

light Toggle Pause if Offline, and then press Enter to change the setting to Disabled.

DNS-3200 User’s Manual 64

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 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. When you start for the first time, you will be asked whether to set or not to set

the manager password for RAID console.

DNS-3200 User’s Manual 68

Notes: 1. The password must consist of at least 6 char-

acters.

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.

After a successful setting of the password, the user is allowed into the primary screen of the RAID Console, where there are four sections (as shown below), which are described as follows:

• Model Number: Model number of the disk.

Array State Area: Available with information on each and every RAID corresponding to each logical disk, including:

• Device: No. of disk RAID

• O.S. Name: Title designated by the operating system to the array. If the array is in a hidden state, it shows Hidden; if it is off line, it shows “??”

• Partition: Number of the corresponding disks of the operating system in the array.

• Array Name: Name given to the array.

• Type: Type of the array.

• Tot a l Cap a cit y : Space available in the array.

• State: The state before the array, which comes in Normal, Critical and Offline.

1.Normal: Array in normal operation.

2.Critical: One or more disk failures make array fault tolerance not available, yet the system has normal access to the array.

DNS-3200 User’s Manual 70

3.Offline: One or more disk failures force the array to go offline, so the system cannot access the array.

• Ta sk : 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.

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.

Note: A Split cannot be cancelled. Online RAID Level

Migration is required to change a split JBOD into a mirror again.

Mirror split as a preset option

1. Select the array to split using the right button of the mouse.

2. On the array menu, select Mirror > Split > Default.

Note: Split arrays will become hidden. To keep them

from being hidden, right-click on the split arrays and select Unhide to cancel the option.

Mirror split as an advanced option

For RAID1N or RAID10N mirrors, advanced options can be used for different splits. When using advanced options, you may first select the disks to be reserved as part of the original array, while the other disks become the second array. For instance, you may split one RAID1N into 2 RAID1N arrays, or keep mirror split on different array controllers.

DNS-3200 User’s Manual 72

2. On the array menu, select Mirror > Split > Advanced and the mir-

ror 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.

The unchecked disks will become

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. A new RAID level needs to be of the same level or higher than the original array.

2. If the system fails during migration, once the system is restarted, the migration will continue.

3. If the hard disk were damaged during migration, as long as both arrays before and after the migration are available with fault tolerance, no data would be lost.

4. Online RAID level migration can build a maximum array capacity of 2.199TB (1MB = 1,000,000 bytes and 1TB = 1,000,000MB).

Online RAID level migration:

1. Select the array to split using the right button of the mouse.

2. On the array menu, select Transform. The Online RAID level

migration window appears (as shown below).

Select the disks from

Source Target array array

3. Select the RAID level to migrate.

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: If you have set the wrong migration configura-

tion, you will not be allowed to press the Commit key. You may have too few disks for the selected RAID level, or not enough space for the selected capacity.

7. Unless the migration is completed immediately, the array list area

will show the RAID in migration.

Chapter 7 System Maintenance

7.1 System Protection & Repairs

DNS-3200 features a large number of advanced technologies for the protection of the system and data, assuring that failure and system down time is minimized. In this chapter, we are giving detailed information about the protection provided for the system and data.

When DNS-3200 is released from the factory, the operating system split area comes in RAID 1N mode, where 10GB of the hard disc becomes a logical disk for the split of the operating system. When the user completes system setup, the mirror split is RAID 1N consisting of 4 hard disks in two RAID 1 arrays (mirrors), one as a disk split area for the primary operating system and the other as a split area for the hidden backup operating system (not accessible). When the primary operating system is unable to turn the system on because of an unstable program, virus infection or human factors, the system can then be switched to the backup operating system mirror to turn the system on for service. The following figure shows the configuration of disks split by RAID 1N.

7.1.1 Operating System Split

When the administrator completes setup of the DNS-3200, including user accounts, permissions, and programs, the operating system is saved using mirror split as the backup method.

1. 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.

Shown as Hidden, The system is not accessible

79 Chapter 7

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.

DNS-3200 User’s Manual 80

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 <Ctrl-R> 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. As only one array (Number 1) can be used to turn on the system, we have to swap the backup system array to the first, so it can be used to turn on the system.

81 Chapter 7

3. Use the Insert key to decide on the 2 arrays to swap. The selected

arrays will be shown in green (as shown below).
