This chapter provides an overview of the Dell™ PowerVault™ 750N and 755N network attached storage (NAS) appliances featur es, as we ll as the information ne cessary to perf orm the initial configuration of the system.

These systems are “headless” systems that are managed through the onboard Ethernet connection; they operate without a keyboard, monitor, or mouse. While it is possible to connect these peripherals to a system, it is generally not necessary unless you are troubleshooting the system. These systems are managed and monitored via a Web-based user interface, the NAS Manager. You can also manage these systems remotely from a client computer attached to the n etwork.

The Boot Process

The internal drives in your NAS appliance are logical small computer system interface (SCSI) drives that are controlled by a hardware redundant array of independent disks (RAID) controller. The Microsoft are installed on two RAID 1 (mirrored) hard-disk drives.

The PowerVault 755N NAS appliance, which is a rack mounted system, uses a split bus and has five drives. One drive is in the drive media bay and four drives are in the standard bay. The operating system is installed on two mirrored RAID 1 drives. Data is stored on the remaining three drives that are configured as RAID 5 drives.

The PowerVault 750N NAS appliance, which can be a tower or rack mounted system, uses a split bus and has eight drives. Two drives are in the drive media bay and six drives are in the drive internal bay. The operating system is installed on the two drives in the media bay, which are configured as mirrored RAID 1 drives. Data is stored on the remaining six drives that are configured as RAID 5 drives.

The boot sequence is as follows:

•CD-ROM drive

• Diskette drive

• Operating system hard-disk drive

System Configuration

You can perform most configuration tasks through the NAS Manager, which is a web browser interface to the NAS appliance. The NAS Manager menus consist of common management tasks grouped under tabs on a menu bar. Each tab on the main menu bar has an associated secondary menu bar associated with it. The secondary menu bar lists the tas ks you can perform from that page. The NAS Manager allows you to perform routine administrative tasks such as shutdown, restart, new share creation, and set user configuration. The NAS Manager home page displays a status indicator and provides a link to the Messages page, which contains details about logged events.

You can access the Terminal Services Advanced Client from the NAS Manager to perform tasks not available directly through the NAS Manager. See “Advanced Features” for more information.

Administrator User Name and Password

To log on to th e NAS Manager, you must enter the administrator user name and password. The default administrator user name is

powervault. To change the user name and password, click Set Administrator Password in

the Welcome window.

administrator and the default password is

Basic Configuration

This section includes information to enable you get your system up and running. You will set the basic configuration from another system that has a keyboard, monitor, and mouse. After you set the basic configuration, you can use the NAS Manager to set passwords, local users, shares, and so on.

NOTICE: If you do not use Kick-Start to configure your system, you must disable Kick-Start

immediately. If Kick-Start is enabled, the system logs in automatically as administrator, which creates a security risk. Kick-Start also takes up system resources by constantly checking for configuration information. For additional information, see “Disabling the Kick-Start Utility.”

There are several ways to configure your system, depending on whether or not you are using Dynamic Host Configuration Protocol (DHCP):

• If DHCP is installed on your network, your system automatically configures the network settings.

• If DHCP is not installed on your network, you can configure your system using a serial connection or the Dell OpenManage™ Kick-Start utility.

Introduction 1-3

Configuring Your System With DHCP

NOTICE: If you do not use Kick-Start to configu re your system, you must disable Kick-Start

When the system is powered on for the first time, it invokes the DHCP client to get parameters (the Internet protocol (IP) address, gateway subnet mask, and domain naming system (DNS) server address) from a DHCP system. The default system name (“Dellxxxxxxx”, where xxxxxxx is the system’s service tag number) is entered as the DNS server name. Connect to the system using Microsoft Internet Explorer 5.0 or later (or for Red Hat Linux only, use Netscape Navigator 6.0 or later) by entering the system name in

www.dell.com | support.dell.com

the Web browser.

NOTE: Microsoft Internet Explorer 4.0 may be used only with Windows NT® 4.0 with Service

Pack 4 or later. All other browse rs are not supported.

If DHCP fails, you need to set the IP address, gateway subnet mask, and DNS server using either a serial connection or the Kick-Start utility.

You can configure the system using the NAS Manager. The NAS Manager is served on port 1279 and is accessed by the URL,https://<systemname | system_ipaddress>:1279, where systemname is the DELL<service_tag>. Port 1279 uses secured socket layers (SSL) to encrypt data going to and coming from the NAS appli ance to provide some data sec u rity.

NOTICE: Although port 1278 can be used, it uses plain text authentication, which can be a

significant security risk. Therefore, using port 1278 is not recommended.

In a system without a DNS server, you can use Internet Explorer (or for Linux only, use Netscape 6.0 or later) to search for the default hostname of the system (“Dellxxxxxxx”, where xxxxxxx is the system’s service tag number).

NOTE: The NAS Manager default administrator user name is administrator and the

Configuring Your System Using the Kick-Start Utility

The Kick-Start utility is soft ware ship ped with your sy stem. This utili ty is us ed to define th e initial network configuration of a system, which makes the system available on the network for complete configuration using the NAS Manager. This utility is intended for customers who have one or more systems to configure but do not want to use the default DHCP assigned address and system name.

A NAS appliance requires configuration information befor e i t can function on the web. You can specify this information locally using the Kick-Start utility installed on the NAS appliance.

You can also supply configuration information using the Remote Kick-Start utility (a browser-based Java applet) to save the configuration information on a diskette or send it to one or more systems across an IP network from another system on the same IP subnet.

Configuration Methods

You can specify configuration information using the following methods:

• Method 1: Remote Configuration — Use the Remote Kick- Start utility located on the Resource CD to enter con figuration information. This method does not require you to attach a mouse, keyboard, or monitor to the N AS appliance (a system without input devices is sometimes called a headless system). You can remotely configure a NAS appliance in one of the following ways:

– Preparing the configuration information for one or more NAS appliances on a

diskette that you create on another system. You can save one configuration or an ordered set of configuration files on a diskette.

www.dell.com | support.dell.com

– Sending the configuration information to the NAS appliance over an IP network.

The system you use must be on the same IP subnet as the NAS appliance.

• Method 2: Local Server Configuration — Use the Kick-Start utility provided on the NAS appliance to specify configuration information directly on the system, which requires you to attach a monitor, keyboard, and mouse to the NAS appli ance. This native version of the Kick-Start utility starts when you turn on the system.

Method 1: Configuring NAS Appliances Remotely

This method allows you to remotely configure one or more NAS appliance, providing the information to the NAS appliance either on a Kick-Start diskette or sent from another system on th e same network IP subnet.

This method is probably the easiest if you are configuring multiple systems. For more information about the multiple configuration feature, see “Notes on NAS Appliance Multiple Configuration Files.”

Starting the Remote Kick-Start Utility

The first step in configuring one or more NAS appliances remotely is to start the Remote Kick-Start utility on another system. On a system running Microsoft Internet Explorer 5.0 or higher or Netscape 6.0 or higher, perform the following steps:

1 Insert the Resource CD into the CD drive.

2 On the main menu, click Dell OpenManage Kick-Start or click the Kick-Start tab.

1-8 Introduction

The Resource CD main menu should appear automatically. If it does not, double-click My Computer on the desktop, right-click the CD drive, and click Autoplay.

4 Click Yes or Grant, depending on your browser, to grant permission so you can

complete the remaining configuration tasks. The Kick-Start window appears where you can create, view, and save configurations by

name. You can then apply them to selected NAS appliances that have been discovered on the network or save the configurations on a diskette or on your local har d-disk drive. The following procedures explain how to perform these tasks.

Creating Configurations

After you start the Kick-Start utility, you are ready to prepare the configuration information that you will apply to one or more NAS appliances. This process works the same way, whether you apply this data using a diskette or using an IP network.

You can save configurations by name and assign them an order within a named set, such as config001, config002, and so on. Also, you can view or edit configurations.

To prepare configuration information, perform the following steps:

1 Double-click Defined Configurations. 2 Click PowerVault NAS Appliance. 3 Click New in the Remote Kick-Sta rt w ind ow. The Configurations List changes to

display the Configuration Form.

4 Select or type the following configuration information:

• Configuration Name — Each configuration file you create must have a name. Using the + (plus) and – (minus) buttons beside the name, you can change the three-digit number that is appended to this name. This number lets you create an ordered set of configuration files on a diskette. An ordered set of configuration files on the diskette can be used to apply configurations in sequence to a group of NAS appliances.

• Time Zone — You can change the time zone by selecting an entry from this list. This is a required field.

• Language — You can change the default system language and locale by selecting a language in the drop-down list. This is a required field.

NOTE: This change does not install the Mu ltilang uage User Interface (MUI) . To install the

MUI or other languages than those that are listed in the Kick-S tart menu, use the

Localization

CD.

• Ethernet Port 0 — This port is the built-in Ethernet port on your system closest to the outside edge of the system. You can opt i onally enter the IP address information for this port. Enter the IP address, subnet mask, and the default gateway IP address. Kick-Start ensures that you have entered all portions of an IP address and checks for a valid IP subnet mask. (Optional field — If you do not complete this field, the system will use DHCP to try to obtain an IP address.)

• Ethernet Port 1 — This port is the built-in Ethernet port on your system farthest from the outside edge of the system. You can optional l y enter the IP address information for this port. Enter the IP address and subnet mask. The gateway IP

address is optional. Kick-Start ensures that you have entered all portions of an IP address and checks for a valid IP subnet mask. (Optional field — If you do not fill in this field, the system will use DHCP to try to obtain an IP address.)

• DNS IP Addresses — You can optionally enter one or two DNS IP addresses. Kick-Start ensures that you have entered all portions of an IP a ddress.

• Host/Machine Name and Domain — The host/machine name is required. It is composed of a base host name and a DNS Domain name. Domain indicates a DNS domain (for example, dell.com) and does not indicate a Windows domain. The domain name is optional.

• Administrator Password — This field is required. You must enter the administrator password twice, and it must be at least six characters long. For security purpo ses, the password does not appe ar o n th e sc reen, but eac h cha r acter of the password shows an aste risk (*) placeholder.

• User Name and Password — You can optionally enter a user login name and password (enter the password twice). For security purposes, the password will not be seen on the screen, but each character of the password will display as an asterisk (*). Passwords of less than six characters will not be accepted.

more than one NAS appliance. Click the + or – buttons to increment or decrement the series number at the right of the configuration name to create an ordered set that use the same name.

You are ready to apply the configuration to the NAS appliance either using an IP network connection or by saving the configurations on a diskette.

Page 25

Configuring NAS Appliances Over an IP Network

If you are configuring multiple NAS appliances on the same IP subnet as the system you use to run Remote Kick-Start , t h is is probably the fastest configur ation method. After starting the Remote Kick-Start utility and creating configurations, perform the following steps:

1 Select the NAS appliance you want to configure from the Discovered Dell Systems

List. If it does not appear, scroll down and click the Integrated DHCP Server check

box and wait a few seconds for the system to be assigned a temporary IP address and discovered by Remote Kick-Start.

NOTE: You must configure the DHCP scope before using the embedded DHCP server. See

"Using the Integrated DHCP Server" in the Kick-Start online help for more information about configuring the DHCP scope.

2 Select an existing configuration file from the list. 3 Click a NAS appliance in the Discovered Dell Systems List, and click Apply. If the

configuration was successful, the status of the NAS appliance in the Remote Kick-Start window changes to Configured (a check mark ic on).

NOTE: If more than one Remote Kick-Start utility runs on your network, you can reserve

the right to configure a system by locking it first. To do this, select the system in the Discovered List and click Lock.

Configuring NAS Appliances Using a Kick-Start Diskette

If the NAS appliance is not on an IP network, you might prefer to create the configuration on a diskette. If you want to configure several NAS appliances with a single diskette, create an ordered set of configuration files on the disk ette, then you can use that disk ette locally at each system to configure it.

After starting the Remote Kick-Start utility and creating configurations, perform the following steps on the system where you have been running Remote Kick-Start:

1 Insert your Kick-Start diskette into the diskette drive of the system where you created

your configurations.

2 Select the configurations you created and saved in the Configurations List and click

Write Diskette.

Applying Configuration Information Using a Kick-Start Diskette

After you have created configuration files on a Kick-Start diskette, you can use the diskette to set up one or more NAS appliances. The Kick-Start utility uses an automatic reading and loading sequence that is especially useful for setting up headless NAS appliances.

Introduction 1-11

Page 26

When you insert the configuration diskette into a NAS appliance diskette drive, Kick-Start looks for configuration files on the Kick-Start diskette. If a configuration file is found, a 20-second countdown timer begins. If the keyboard or mouse are inactive during the 20-second interval, Kick-Start applies the configuration settings found in that file.

Kick-Start looks for the configuration files on the diskette. If found, it selects and applies a configuration to the NAS appliance, AND then marks the file as having been applied. Configuration files for NAS appliances have a .nas file extension. For more information about the multiple configuration feature, see “Notes on NAS Appliance Multiple Configuration Files.”

The Kick-Start utility skips files marked Applied the next time you use the diskette to

www.dell.com | support.dell.com

configure a system and advances to the next nonapplied file in the list. To set up one or more NAS appliances, perform the following steps:

1 Turn on your NAS appliance. 2 Insert the configured Kick-Start di skette i n to the diskette drive of the first NAS

appliance you want to set up. For the first 30 seconds, the diskette drive light turns on and indicates that the

diskette drive is active while Kick-Start r eads and loads a configuration file for the NAS appliance. When the drive light turns off for more than 30 seconds, Kick-Start has finished applying the configuration.

The NAS appliance automatically reboots.

3 If you customized the Kick-Start diskette to contain multiple configurations, go to the

Method 2: Configuring a NAS Appliance Locally

This section describes how to enter configuration information locally on a NAS appliance. You do not need a Kick-Start diskette for this method.

optional, but it can be used in this procedure for simplicity.

The Kick-Start window appears, prompting you to either insert a configuration diskette or click Enter Configuration Information to directly configure the server. On the left side of the screen you may select from the available languages.

Page 27

2 Click Enter Configuration I nfo rmation. 3 Select the items you want to configure and click Next.

Your choices are:

• Ethernet port 0

• Ethernet port 1

NOTE: The Kick-Start utility Ethernet 0 matches Windows Local Area Connection, and

Ethernet 1 matches Local Area Connection 2.

• Domain name server (DNS)

• Host/system name and domain (domain is a DNS Domain, not a Windows domain. For example, www.dell.com.)

•Administrator password

• User name and password

NOTE: The user you set up in this step does not have administrator privileges.

Type your configuration information into the provided text boxes and click Next.

5 Click Yes when prompted to apply your configuration settings to this system.

After a 10–15 second delay, your NAS appliance reboots when the configuration process is complete. At the prompt, you can log in as administrator with the password you specified in step 3.

Notes on NAS Appliance Multiple Configuration Files

Using Remote Kick-Start, you can create multiple configuration files on the Kick-Start diskette. At the top of each conf iguration form, a Configuration Name field appears. You can use this field to enter information that helps you identify a p articular machine, such as, rack1-slot2, netserver-1, and so on.

Using the + (plus) and – (minus) button s n ext to this fie l d, yo u ca n change the thr e e-digit number that Remote Kick-Start appends to the configuration name. The name of the configuration file is formed by appending this three-digit number at the end of the configuration name. Files with the same name but a differ e nt thr ee-digit number are called an ordered set.

The configuration process uses the three-digit number at the end of the filename to determine which configuration to apply next. Because names of the configuration files are important to the configuration process, you must not alter the configuration filenames after they are written to the diskette.

Introduction 1-13

Page 28

Do not save more than one ordered set of configuration files on a single diskette, which creates more than one file with the same three-digit number. Kick-Start uses these three-digit numbers exclusively to decide which configuration to apply next. Thus, putting multiple configuration sets on a single diskette prevents you from knowing which configuration you are applying.

For example, if the Aaaa#001.nas and Bbbb#001.nas files are both stored on the same configuration diskette, there is no guarantee that Aaaa#001.nas will be applied first (even though it is alphabetically first) .

Disabling the Kick-Start Utility

www.dell.com | support.dell.com

If you do not use Kick-Start to configure your system, you must disable Kick-Start immediately. If Kick-Start is enabled, the system logs in automatically as administrator, which creates a security risk. Kick-Start also takes up system resources by constantly checking for configuration information.

To disable Kick-Start, perform the following steps:

1 From the NAS Manager primary menu, click Maintenance. 2 Click Terminal Services. 3 Log onto the system as an administrator. 4 Click the X on the top, right- hand corner of the Kick-Start windo w.

A Warning window displays that asks whether you want the Dell OpenManage Kick-Start configuration too l to run automatically each time the machine starts.

Using Shares

A folder on your NAS appliance can be shared with other systems on the network, whether those systems are running a Microsoft Windows operating system or a Unix operating system.

www.dell.com | support.dell.com

A NAS appliance suppor ts the following method s of sharing folders:

• CIFS — The Common Internet File System protocol is used by clients running a Windows operating system.

• NFS — The Network File System protocol is used by clients running UNIX

• AppleTalk — The Appletalk protocol is used by clients running a Macintosh operating system.

•NCP (Novell

• FTP — The File Transfer Protocol is an alternative way of accessing a file share from any operating system.

• HTTP — The Hyptertext Transfer Protocol is the protocol for accessing a file share from Web browsers.

When you create a share on the appliance, you can enable any or all of the listed protocols. You can add and manage shares from the NAS Manager.

NetWare®) — The NCP protocol is used by NetWare clients.

Managing Shares

The Shares page allows users to create, open, delete, or configure a variety of network folders. The Shares page displays a Shared Folders table that has the following columns:

• Share Name lists each shared folder by name. To create, open, delete, or configu re the properties of a giv en s h are, click the radio

button next to the name of the share you want to modify.

• Share Path displays the share path.

2-4 NAS Manager

Page 33

• Type indicates the share type: –W = Windows (CIFS)

– U = UNIX (NFS) –F = FTP –H = HTTP – A = Apple (AppleTalk) –N = NetWare (NCP)

• Comment displays a brief description of the share, if one has been provided.

• Tasks lists the tasks that can be performed for each selected item.

Use this table to select a share, and then click the task you want to perform from the Tasks list (located to the right of the table).

Adding a Share

To create a share, you must supply a share name (the name of the directory on the NAS appliance that is to be shared) that is unique from all other shares on the system. Some protocols also support the inclusion of a comment or brief description of the share. Additionally, you must enable at least one of the available protocols.

Although a single user interface is provided for creating a share for all protocols, it actually creates a separate share for each protocol. You can remove a share for one protocol without removing the share for the other protocols; however, this process can be quite confusing. Therefore, it must be done carefully.

NOTICE: Do not create any data shares on the operating system hard-disk drive. Using the

Reinstallation

CD will destroy all data on the operating system hard-disk drive.

To add a share, perform th e following steps:

1 On the NAS Manager primary menu, click Shares. 2 In the Tasks list on the Shared Folders page, click New. 3 On the General tab, enter the Share Name, Share Path, (and if desired) a brief

description of the share in the Comment field.

NOTE: The Comment field is ignored for NFS, FTP, and HTTP shares.

4 Check the appropriate box(es) to specify which types of protocols to enable. The

available options are: Microsoft Windows (CIFS), UNIX (NFS), Novell NetWare, Apple Macintosh, FTP or HTTP

NAS Manager 2-5

Disk Quotas

Disk quotas track and control the use of disk space for volumes. Yo u can configure the volumes on your NAS appliance to do the following:

• Prevent further disk space use and log an event when a user exceeds a specified disk

www.dell.com | support.dell.com

space limit.

• Log an event when a user exceeds a specified disk space warning level.

When you enable disk quotas, you can set both the disk quota limit and the disk quota warning level.

• The disk quota limit specifies the amount of disk space a user is allowed to use.

• The warning level specifies the point at which a user is nearing his or her quota limit.

F or example, you can set a user's disk quota limit to 50 megabytes (MB), and t he disk quo ta warning level to 45 MB. With these settings, the user can store no more than 50 MB on the volume. If the user stores more than 45 MB on the volume, you can set the disk quota system to log a system event to the event log.

In addition, you can specify a quota limit for the users but let the users exceed that quota limit. Enabling quotas and not limiting disk space use is useful when you want to track disk space use on a per-user basis, but do not want to deny users access to a volume when they exceed that limit. You can als o speci fy whether or not the system should log an event when a user exceeds either their quota warning level or their quota limit.

Enabling Disk Quota Management

To enable or disable quota ma nagement on a volume, perform the following steps:

1 On the primary menu of the NAS Manager, click Disks. 2 Click Disk Quota. 3 On the Volumes and Quotas page, select the volume to manage. 4 On the Tasks list, select Quota.

2-8 NAS Manager

Page 37

5 On the Default Quota for volume page, click the appropriate check box to enable or

disable quota management.

6 Select the desired quota size and settings for this volume.

Adding Disk Quota Entries

The Quota Entries page allows you to add, delete, or configure disk quotas for any user of the NAS appliance.

When you enable disk quotas for an existing volume, volume usage is auto matically tr acked for new users from that point on. However, existing volume users have no disk quotas applied to them. You can apply disk quotas to those existing volume users by adding new quota entries in the Quota Entries window.

To add a new quota entry, perform the following steps:

1 On the NAS Manager primary menu, click Disks. 2 On the Disks page, select Disk Quota. 3 On the Disk Quota page, select the volume to manage. 4 From the Tasks list, select Quota Entries. 5 On the Tasks list, select New…. 6 Select a local user from the list box, or type the name of a domain account in the text

box (using the <domain name\user name>).

Although the Dell OpenManage™ Array Manager provides a comprehensive solution to storage management, you should use it only for advanced features that cannot be performed from the Disks tab in the NAS Manager. You can access the Array Manager through the Terminal Services Advanced Client in the NAS Manager.

Array Manager allows you to configure your storage devices and the logical volumes contained in your system. Array Manager displays storage configuration in both a physical and a logical view. The physical view shows the physical connections between the storage devices. The logical view shows a logical representation of your storage as logical volumes.

Array Manager provides a single console for array and volume configuration, from which you can do the following:

www.dell.com | support.dell.com

• Manage the hardware redundant array of independent disks (RAID) solution

• Display all of your storage information in a graphical environment

Array Manager Common Tasks

This section provides a high-level description of the most common procedures performed under Array Manager.

Creating a New Volume

1 Create a RAID 5 virtual disk from the available pool of physical drives. 2 Write a signature to the disk created. 3 Upgrade the disk to dynamic. 4 Create a new volume on the upgraded disk. 5 Assign the next available drive letter and format the volume NT File System (NTFS).

NOTE: The PowerVault 750N and 755N only support NTFS partitions. Formatting all

partitions as NTFS allow for advanced features only available under that file system.

Deleting an Existing V o lume

1 Select and delete the desired volume. 2 Revert the disk that contained the volume to a basic disk. 3 Determine the virtual disk that corresponds to the basic disk. 4 Delete that virtual disk.

3-2 Advanced Disk and Volume Management Using Array Manager

Page 49

Expanding an Existing Volume

1 Find the virtual disk that corresponds to the volume you are going to expand. 2 Add a member to that virtual disk.

NOTE: After adding a member to a virtual disk, the virtual disk is reconstr ucted by the

adapter. This operation will take several hours.

After the virtual disk has completed the reconstruction process, perform a rescan.

3 4 Extend the specified volume with the new space available to the virtual disk.

Array Manager Console

The Array Manager console display uses a tree view to display storage objects in the left pane of the window , and tabbed views in the right pane to display additional information on storage objects. The following sections provide more information about the left and right panes.

Left Pane

The left pane shows the objects detected by the Array Manager software. The major storage objects are the local computer object, arrays, disks, and volumes. By clicking the plus sign (+) in front of a storage object, you can see the subordinate storage objects under that object.

• Arrays represent the physical and logical storage subsystems connected to RAID controllers.

• Disks represent the disks recognized by the Microsoft system.

• Volumes include dynamic RAID volumes created in Array Manager, primary and extended partitions, logical drives associated with extended partitions.

• My Network Places, History , and Favorites prov ide remote connection functionality not supported by the PowerVault 750N and 755N systems and should be ignored.

Right Pane

The right pane identifies the various objects and their status, and displays any error conditions that might exist. The four tabbed views in the system’s right pane console view include the following:

•The General tab displays parameters based on the objects you select in the console's tree view. The parame ters are as follows:

– Name is the name of the object. – Status can vary, depending on the object. Common status conditions are Online,

Healthy, and Resynching.

www.dell.com | support.dell.com

– Type identifies the object, such as Array Disk. – Disk Group shows an entry for disks in a basic or dynamic group. – Capacity is the maximum size of the disk. – Unallocated Space is the amount of free hard-disk space still available. – Graphical Layout is a graphical representation of how much of the disk is being

used. – Progress shows the current progress (percentage of completion) for tasks. – Device is the type of disk: small computer system interface (SCSI), integrated

drive electronics (IDE), and so on. – Port identifies the controller card. A SCSI port has zero or more target IDs, and a

target ID has one or more logical unit numbers (LUNs). – LUN is the logical unit number. – Target is the SCSI ID, which uniquely i dentifies the disk on the controller card. – Vendor identifies the vendor on hardware objects.

•The Events tab displays event log messages associated with storage objects.

•The Disk View tab displays a graphical layout of the disks on your system, including CD or other r em o vable media.

•The DM View tab is grayed-out on the Array Manager console.

Managing Disk Arrays

This section describes how to configure and manage arrays with the Dell™ PowerEdge™ Expandable RAID Controller 3/Dual Channel (PERC 3/DC) and PERC 3/QC controllers that are included with the PowerVault 750N or 755N NAS appliance. The PERC 3/DC and PERC 3/QC controllers are high-performance intelligent PCI-to-SCS I host adapters with RAID capabilities. Each channel supports SCSI data transfer rates of up to 160 megabytes (MB) per second per channel. You can create a maximum of 40 virtual disks per controller.

The following topics are discussed:

• Recommended virtual disk configuration

•Creating virtual disks

• Deleting virtual disks

• Reconfiguring and managing virtual disks

Recommended Virtual Disk Configuration

It is recommended that each virtual disk created on your system's external SCSI enclosures contain 11 physical drives and be configured as a RAID-5 virtual disk. Virtual disks configured in this manner are optimized b y the PERC 3/DC or PERC 3/QC adapter to provide the best performance. You are also recommended to as sign a gl obal hot sp ar e w it hin the same enclosure for each virtual disk.

Creating Virtual Disks

NOTE: The maximum supported volume size is 2 terabytes (T B).

The first step in configuring your system for improved system management is creating virtual di sks.

Advanced Disk and Volume Management Using Array Manager 3-5

Page 52

NOTE: When you create virtual disks, you might want to consider how virtual disks will be

deleted. Virtual disks created on the PERC 3/DC or PERC 3/QC controller must be deleted in reverse order of their creation. In other words, you must delete the most recently created virtual disk first and continue to delete in reverse order.

NOTE: To take advantage of all the system features such as Defrag and Encryption, you are

recommended to use the default value of 64 KB for the stripe size when creating a virtual di sk.

To create a virtual disk, pe rform the following steps:

1 Right-click on an array group. 2 Click Create Virtual Disk to launch the Create Virtual Disk Wizard. 3 Read the Welcome screen and click Next to continue.

www.dell.com | support.dell.com

The Select Creation Mode dialog box displays. You can cancel the operation at any time by clicking Cancel.

4 Select Custom Mode and click Next to continue.

The Select Disks and Virtual Disk Attributes screen displays.

5 Select the disks and confirm information presented in the wizard.

NOTE: The PowerVault 750N and 755N only supports NTFS partitions. Formatting all

partitions NTFS al lows for advanced features only available under that file system .

Click Next to continue. The Completing the Create Virtual Disk Wizard dialog box displays.

7 Click Finish to create a virtual disk or Back to return to the previous screen.

Array Manager conf ir ms the creation of the vir tual disk. The Rescan Disk Layout checkbox is selected by default. Rescan Disk Layout allows

the Microsoft

Windows® Powered operating system to recognize the new virtual disk. You can perform a Rescan Disk Layout later if the box is not checked when you create the virtual disk.

Deleting Virtual Disks

Deleting a virtual disk permanently deletes all information contained on that disk. Virtual disks created on the PERC 3/DC or PERC 3/QC controller must be dele ted in the reverse order that they were created. In other words, the last disk that you created must be deleted first.

NOTICE: All data on the virtual disk is lost when the disk is deleted.

This section summarizes how you can change the virtual disk configuration through the NAS Manager. The following topics are discussed:

• Using add member

•Using transform type

• Using change policy

• Using check consistency

• Initializing disks

•Properties

NOTE: Because of hardware restrictions, the PERC 3/DC and PERC 3/QC controllers will not

detect a drive status change until you attempt to read from or wri te to the drive. For example, when an unconfigured drive is removed, the controller will not detect the change until a you perform a manual rescan or read/write to the drive.

The Rebuild Rate command changes the rebuild rate settings. The rebuild rate is the fraction of the compute cycles dedicated to rebuilding failed drives. A rebuild rate of 100 percent means the system is totally dedicated to rebuilding the failed drive.

NOTICE: The default rebuild rate is 30%. System performance might be degraded if you

change the rebuild rate to a higher value than the default.

The PERC 3 rebuild rate can be configured between 0% and 100%. At 0%, the rebuild is only done if the system is not doing anything else. At 100%, the rebuild rate has a higher priority than any other system activity.

Disk Management

This section describes conceptual and procedural information about how Array Manager implements basic and dynamic disks.

The following topics are discussed:

• Writing a disk signature

• Upgrading a basic disk to a dynamic disk

• Reactivating dynamic disks

• Merging foreign disks

Writing a Disk Signature

When you create a virtual disk and perform a rescan, the newly created virtual disk appears under the Disks node. The unsigned disk displays an error bitmap on the icon. The Disk Type is Unsigned Disk. The unsigned disk cannot be used cannot be used until it has a signature on it.

3-14 Advanced Disk and Volume Management Using Array Manager

Page 61

To write a disk signature, right-click on the unsigned disk. A menu displays showing the Write Signature command. (The Write Signature command appears only if a disk does not have a signature on it.) Select this command to write a signature on the disk.

After a signature is written on a disk, the disk displays as a Basic Disk. You can create partitions on the basic disk, or you can upgrade the disk to dynamic to create volumes on it.

NOTE: Upgrade all data disks on the system to dynamic before creating any v olumes. This

allows the system to support online volume extension. Eve n though it is possible to upgrad e disks with existing volumes to dynamic, those volumes cannot be extended. Only volumes created on disks that are already dynamic can be exte nded.

NOTICE: Because of system recovery limitations, the operating system disk must remain a

basic disk. All other disks should be upg r aded to dynamic durin g creation.

Upgrading a Basic Disk to a Dynamic Disk

Because only dynamic disks can be used for online volume extension, you are recommended to use Array Manager to upgrade all data disks on your system to dynamic. The upgrade includes new disks, which are added to the system as basic disks.

NOTICE: Because of system recovery limitations, the operating system disk must remain a

basic disk. Do not upgrade your operating system disk to dynamic.

To upgrade a basic disk to a dynamic disk, perform the following steps:

1 Right-click the disk you want to upgrade and click Upgrade Dynamic Disk.

The Upgrade Disk Wizard provides information about upgrading.

2 Click Next to continue.

You are asked to select the disks to upgrade.

3 Add the basic disks you want to upgrade to the list of dynamic disks and click Next. 4 Click Finish.

NOTE: After a disk is upgraded to dynamic it cannot be reverted back to basic unless all

volumes on that disk are removed. You are strongly recommended not to revert a disk back to basic after data volumes are present.

Page 62

Reactivating Dynamic Disks

A dynamic disk might appear as a missing disk when it is corrupted, powered down, or disconnected. You can reactivate a dynamic disk to bring it back online by performing the following steps:

1 Right-click the disk marked Missing or Offline dynamic disk. 2 Click Reactivate Disk on the menu.

The disk should be marked Online after the disk is reactivated.

Merging Foreign Disks

www.dell.com | support.dell.com

Dynamic disks with a foreign status are disks that have been moved from another system. You cannot reactivate a foreign dis k; you must merge the disk to the sy stem. To change the status of a foreign disk and enable it to be seen as a part of the current system, use the command Merge Foreign Disk.

Perform the following steps to merge foreign disks:

1 From the PowerVault NAS Manager, log on to the Terminal Services Advanced Client. 2 Launch the Dell OpenManage Array Manager by clicking the System Management in

the Advanced Administration Menu, and then clicking Computer Manageme nt. Foreign disks will appear in the disk list and graphical views as Foreign.

3 Right-click a foreign disk and click Merge Foreign Disks.

The Merge Foreign Disk Wizard displays.

4 Select the foreign disks that you would like to merge to the system.

By default all foreign disks are selected to be merged.

5 Click Next. 6 Click Next again to validate the volume status of each foreign disk. 7 Click Finish.

The following topics are discussed:

• Volume overvie w

• Checking volume properties

• Formatting a partition or volume

• Deleting a partition or volume

Volume Overview

A volume is a logical entity that is made up of portions of one or more physical disks. A volume can be formatted with a file system and can be accessed by a drive letter.

Like disks, volumes can be basic or dynamic. In Array Manager, basic volumes refer to all volumes that are not on dynamic disks. Dynamic volumes are logical volumes created from dynamic disks with Array Manager.

In your system, create all data volumes and dynamic volumes on dynamic disks. Only the operating system drive should remain basic because of system recovery limitations.

Checking Partition or Volume Properties

1 Right-click the partition or volume to be checked. 2 Choose Properties from the context menu.

The Properties window displays.

3 Check the properties for your volume.

F o rmatting a Partition or Volume

1 Right-click the volume or partition you want to format and then click Format. 2 Choose NTFS as the file system type.

NOTE: The PowerVault 750N and 755N only supports NTFS partitions. Formatting all

partitions as NTFS allow for advanced features only available under that file system.

Enter a label for the volume.

The label appears on the Array Manager console. If a name has been selected, this name appears in the Name field. You can change the name by typing a different name.

4 Enter an allocation size or use the default, which is automatically selected.

Recovery From System Failure

If the Windows Powered operating system becomes inoperable, you can use the Reinstallation CD for your system to reinstall the operating system. After the operating system is reinstalled, the system state backup can be restored to recover system configuration information.

Operating system reinstallation includes the following procedures:

• Reinstalling the operating system using the Reinstallation CD.

• Performing system setup

• Restoring the system state backup (see “Restoring System State Data” for more information)

Reinstalling the Operating System

NOTICE: When using the

drive.

Insert the Reinstallation CD into the CD drive.

1 2 Shutdown the system. 3 If one or both existing operating system disks are operational, proceed to step 4.

If both operating system mirrored drives (small computer system interface [SCSI] drives 0 and 1) have been replaced with new, initialized drives, you must remove all of the internal data drives. You do not need to compl etely remo ve the in terna l data dri ves from the enclosure. You only need to pull the internal data drives out far enough to ensure that they are disconnected from the backplane. Ensure that you leave only the two new operating system drives installed in the internal drive b ays.

Reinstallation

4 Turn on the system.

The Reinstallation CD automatically starts the installation p rocess if the system is a Power Vault 750N or 755N NAS appliance and i f the firs t lo gical volume configured on the RAID controller is a drive in a two drive RAID 1 group.

It takes up to 30 minutes for the system to reinstall.

NOTE: The CD ejects approximately 7 minutes into the installation time. The ejection of

the CD does not indicate an error or that the process is finished.

If you had two new, initialized drives in step 3, reinsert any internal data drives that

were removed prior to the operating system reinstallation after the CD has ejected. Otherwise, proceed to step 6.

6 Use a Web browser to connect to the system. 7 Use the Dell OpenManage™ Array Manager to merge into the system any data

containers that were previously defined. (See the “Merging Foreign Disks” section in “System Recovery, Backup, and Restore” for more information about merging disks.)

Initial System Setup

After the operating system is reinstalled on the system, you should configure the system again to establish network communication. If Kick-Start is used for configuration, insert your Kick-Start diskette after the CD drive tray ejects the Reinstallation CD. See “Introduction” for information on initial system configuration.

System State Backup and Restore

Integrated Windows 2000 backup and recovery tool s allows administrators to back up and restore the system state data.

System state data includes the following:

•Registry

• COM+ class registration database

• System boot files

• Users and groups information

• CIFS/NFS/Novell

NetWare®/Macintosh share data

System Recovery, Backup, and Restore 5-3

so that it is able to backup user shares. You can find this option in Tools—> Options menu on the Network tab.

12 In the Veritas Backup Exec Backup Selections window, browse to your NAS appliance

under Entire Ne twork.

13 Select the share name that you created for your persistent image. 14 Deselect the Persistent Storage Manager State directory when performing persistent

image backups. This directory contains files needed for persistent images. However, to save space on your backup media, backing up these files is not recommended.

15 Click Backup. 16 Select Run Now to run the ba ckup now or Schedule to schedule your backup job to

run at a later time.

NOTE: Although you are backing up your persistent image from a Network Share, it will not

create network traffic if you are backing up to a local backup device.

Limitations on Backing Up Persistent Images

• You cannot do incremental or differential backups of persistent images.

• You cannot use GFS rotation schemes when backing up persistent images.

• You cannot schedule a backup of a persistent image. You must do a manual backup of persistent image files because each persistent image

file name is unique in that it includes the date and time (hour-minute-second) that the persistent image wa s taken.

• When you restore a persistent image, you must redirect the restore to a location other than the original persistent image location. A restore to the original location will not be successful.

Restoring Pers istent Images From Tape Backup

NOTE: Do not use Computer Associates ARCserve to restore persistent images.

To restore your persistent images from ta pe backup, perform the following steps:

SECTION 6

Dell ActiveArchive™

Page 88

Dell ActiveArchive allows the creation and preservation of persistent images of Dell PowerVault™ 750N and 755N system data volumes. The Dell ActiveArchive software is installed on all PowerVault 75xN systems. It can be configured by using the NAS Manager.

This chapter provides information on the following topics:

• Introduction to persistent images

• Scheduling persistent images

• Adding persistent images to the schedule

• Deleting a persistent image schedule

• Editing the properties of a persistent image’s schedule

www.dell.com | support.dell.com

• Taking a new persistent image

• Deleting a persistent image

• Configuring the persistent image environment

• Setting persistent image retention weights

• Accessing persistent images

•Restoring a volume

Introduction to Persistent Images

A persistent image is a point-in-time co py of a disk volume. Unlike conventional volumes, the information in the persistent image is static. A persistent image contains an exact copy of the file system at the time the persistent image was created. If you change a file on the active file system after taking a persistent image, the persistent image contains the old version of the file. If an active file gets corrupted or deleted, you can restore the old version by copying the file from the latest persistent image. Also, because the persistent image contains the contents of the file system when the persistent image was taken, you can perform a backup from the persistent image without stopping all I/O to the file servers, thus eliminating the backup window required by other types of backup.

NOTE: Persistent images are temporary backups of your data that reside on the same volume as

your data. If the volume becomes damaged, you lose your data including the persistent image. Therefore, persistent images do not replace regular backups of your volume.

6-2 Dell ActiveArchive™

Page 89

Cache File

The Dell ActiveArchive software stores changed data in a cache file. A cache file resides on each volume of your system. By default, the persistent image cache file is 20 percent of each volume. You can use the NAS Manager to chang e the percentage of the volume that is dedicated for the cache file.

NOTE: You cannot take a persistent image of the operating system drive (C:).

Cache Thresholds

The Dell ActiveArchive software has two thresholds that provide warnings when the cache file is approaching maximum capacity. The Cache Full Warning Threshold logs an event in the event log and displays an error in the NAS Manager status indicator when the cache file reaches the threshold (default is 80% full). The Cache Full Threshold, which is labeled Begin deleting images in the NAS Manager, specifies the threshold where the PowerVault NAS Manager deletes the oldest persistent images with the lowest retention weights until the cache file is below the Cache Full Threshold (default is 90% full).

Persistent Image Retention Weights

When the system reaches the cache full threshold, the system starts deleting files depending on the retention weight and age of the persistent image. The system first looks for the persistent image wi th the with the lowest retention weight in the cache file and deletes the oldest persistent image with that retenti o n weight. After all persistent images with that lowest retention weight have been deleted, Dell ActiveArchive looks for and deletes the oldest files with the next higher retention weight.

Persistent Image Considerations

When using persistent images, system performance may be degraded, depending on the rate your data is changing and the number of persistent images kept for each virtual disk. Read performance of the virtual disk remains constant, regardless of the presence of persistent images. Read performance of the persistent im ag e is identical to that of the virtual disk. Write performance, however, may vary. Each initial write to a virtual disk area causes the Dell ActiveArchive software to rewrite the data to the persistent image cache file, and the initial write is slower if the data is being protected by a persistent image. Changes to data that is not protected by a persistent image will not cause a performance degradation.

NOTICE: If you use the

images will be deleted.

Storing Persistent Images

You can store up to 250 persistent images per volume; however, if you exceed 250 persistent images, the oldest per si stent image with the lowe st retention weight is overwritten. This number of persistent images allows you to schedule multiple persistent images. For example, you could implement a typical schedule similar to the following schedule. (You should tailor your schedule depending on how the data is changing.)

• Seven daily persistent images

• Two weekly persistent images

• Two monthly persistent images

www.dell.com | support.dell.com

Accessing Directories, Folders, and Files

By default, administrators can access the ActiveArchive directory in the root of each volume. Each persis tent image is displayed s e parately with a date and ti m e stamp showing when the persistent image occurred. The administrator can browse the persistent image as if it were a standard volume. To access the ActiveArchive directory from the NAS Manager home page, click Disks and then click ActiveArchive. Each persistent image is mounted as a volume on the file system to allow access by clients. Persistent images are created as read-only.

Pers istent image dir ectories ar e used in the same way that conventional dir ectories ar e used. The files and folders in the persistent image directories have the same permissions as the files and folders on the original volume. All persistent images are persistent and will survive system power losses or reboots.

NOTE: The ActiveArchive directory is a hidden folder. You must configure your system to view

hidden files and folders to view your ActiveArchive directory.

Allowing User’s Access to Persistent Images

To allow user’s to access the persistent images, the system administrator must modify the permissions for the ActiveArchive directory. The files and folders within a persistent image are identical to the permissions on the original files and fo l d ers. Use the PowerVault N AS Manager to change the ActiveArchive directory permissions by performing the following steps.

6-4 Dell ActiveArchive™

Page 91

NOTE: To use the PowerVault NAS Manager you must be logged in as Administrator. The

PowerVault NAS Manager default administrator use r name is administrator and the default password is powervault.

1 On the NAS Manager primary menu, click the Maintenance tab . 2 Click Terminal Services. 3 Log on to a Terminal Services Advanced Client session. 4 Open the Explorer. 5 Select the drive on the left side. 6 Right-click the ActiveArchive directory and click Properties.

7 Click the Security tab and click Add....

8 Add individual users or groups. 9 Give the selected members Read and List Folder Contents permissions.

Repeat these steps for the ActiveArchive directory on each volume the users will access. Y ou do not need to change the permissions of the persistent images a nd their subdirectories. These files and folders will retain the original files’ and folders’ permissions.

Preparing Your Volumes for Persistent Images

Before you take or schedule persistent images, you must prepare each of your volumes for persistent images. This process creates the cache file and other files needed for taking persistent images.

NOTE: This process might take several hours.

To prepare your volume for persistent images, perform the following steps:

1 On the NAS Manager primary menu, click Disks and then click ActiveArchive. 2 Click Volume Settings. 3 Click the radio button adjacent to the volume you want to prepare.

4 Click Configure... .

5 Use the drop-down menus to configure the required options. For information about

the options, see Configuring Persistent Image Volume Settings.

6 Click OK to start the prepare process.

Dell ActiveArchive™ 6-5

Page 92

Scheduling Persistent Images

NOTE: Before scheduling persistent images, prepare each of your volumes for persistent

images. (See the Preparing Your Vol umes for Persistent Images.)

When you click Disks and then ActiveArchive, the Scheduled Persistent Image page displays a list of all scheduled persistent images and associated tasks. Each scheduled persistent image is identified by the scheduled time, day, frequency, starting date, and target volume ID. Persistent images are identified by time and date, and are located in the ActiveArchive directory. The ActiveArchive directory is located in the root of each ActiveArchive vol u me. Only the Adminis tr ator can access the ActiveArchive directory. The files and folders in the persistent image directories have the same permissions as the files

www.dell.com | support.dell.com

and folders on the original volume. Persistent image directories are used e xactly the same a s conventional system volumes. Unlike conventional volumes, read-only persistent image images are static, recording the precise content of the originating volume at the time you created the persistent image.

Displaying the List of Persistent Images

The Persistent Images page displays all current active persistent images. Each entry identifies the date and time the persistent im age was created and the volume it preserves. Select an individual persistent image by clicking the radio button to the left of the description.

1 On the NAS Manager primary menu, click Disks, then click ActiveArchive.

2 Click Persistent Images.

Adding Persistent Images to the Schedule

You can use patterns in the persistent image name to differentiate your persistent images. For example if you use a pattern of Snapshot. % i and you take two persistent images, you would have Snapshot.1 and Snapshot.2. The default persistent image name pattern is Snapshot %M-%D-%Y %H.%m.%s. V alid pattern macros are as follows:

•%M = Month

•%D = Day

•%Y = Year

• %h = Hours in 12-hour format

• %H = Hours in 24-hour format

Configuring the Persistent Image Global Settings

You can use drop-down menus to modify the various aspects of the persistent image environment.

1 On the NAS Manager primary menu, click Disks, and then click ActiveArchive.

2 Click Global Settings and configure the following options.

NOTE: Before changing the Image Directory Name, you must delete all existing persistent

images.

• Maximum Persistent Images — Specifies the maximum number of active persistent images per volume, up to a maximum of 250. When the volume has

www.dell.com | support.dell.com

250 persistent images stored, starting another persistent image will overwrite the oldest persistent image with the lowest retention weight.

• Inactive Period — Prior to starting a persistent image, the system waits for a period of relative inactivity on the volume being imaged. The default value for this period, which is fi ve seconds, allows systems to start an image with a consis tent file set and a minimal time-out. Experienced administrators may reduce or increase this value for system optimization. Reducing the inactive period allows persistent images to begin on systems where disk inactivity is rare, at the possible expense of synchronization problems within applications that are concurrently writing to multiple files.

• Inactive Time-Out — Specifies the amount of time the server should continue to retry to create a persistent image (default 15 minutes). A persistent image will not start until a perio d of r el ative i nact ivity, specified by the Inactive Period, occurs. If an interval longer than Inactive Time-Out passes before the persistent image can begin, the persistent image will not be taken and an error will be displayed in the NAS Manager status indicator and an error will be logged in the event log.

• Image Directory Name — Specifies the directory name which will be used for the persistent image mount point. Each persistent image appears as a subdirectory in the volume which is being imaged. The entire content of the volume, as it e xis te d when the persistent image was created, appears under this directory.

Rest ore Defaults reestablishes the system defaults.

Configuring Persistent Image Volume Settings

You can use drop-down menus to modify volume settings.

1 On the NAS Manager primary menu, click Disks and then click ActiveArchive. 2 Click Volume Settings.

6-10 Dell ActiveArchive™

Page 97

3 Click the radio button adjacent to the volume setting you want to change.

4 Click Configure... .

5 Use the dropdown menus to configure the following options.

NOTE: Before changing the cache size, you mu st delete all persistent images on that

volume.

• Cache Full Warning Threshold — Defines the percentage of cache space used that will trigger warning m essages to the system event log.

• Begin Deleting Images — Defines the percentage of cache space used that will trigger automatic deletion of the oldest persistent images with the lowest retention weight on the system. Automatic persistent image deletions are recorded in the system log.

• Cache Size — Specifies the percentage of the volume that is allocated to the cache file. Increasing this value will allow more and larger persistent images to be maintained. Ensure that adequate space is available on the persistent image files location drive.

6 Click OK.

Accessing Stored Persistent Images in ActiveArchive

NOTE: Only Windows clients (CIFS) can access Dell ActiveArchive persistent images. NOTE: The name of the utility that creates persistent images is Dell ActiveArchive. The name of

the directory where Dell ActiveArchive persistent images are stored is ActiveArchives.
