Introduction
support.dell.com
This chapter provides an overview of the Dell™ PowerVault™ 735N network attached storage (NAS) appliance features, as well as the information necessary to perform the initial configuration of the system.
This system is a “headless” system that is managed through the onboard Ethernet connection; it operates without a keyboard, monitor, or mouse. While it is possible to connect these peripherals to the system, it is generally not necessary unless troubleshooting the system. This system is managed and monitored via a Web-based user interface, the Dell PowerVault 735N NAS Manager. You can also manage the system remotely from a client computer attached to the network.
The Boot Process
The Microsoft
®
Windows
®
Powered operating system and boot sectors are installed on the first internal hard-disk drive. All five internal drives are controlled by a hardware redundant array of independent disks (RAID) controller. The operating system drive is configured by a single RAID 0 drive and is the first logical small computer system interface (SCSI) drive (SCSI ID 0). The remaining four drives (SCSI ID 1-4) are configured into a RAID 5 drive group.
The boot sequence is as follows:
•
Diskette drive
•
CD-ROM drive
•
Operating system hard-disk drive
System Configuration
You can perform most configuration tasks through the PowerVault NAS Manager. The
PowerVault 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 tasks you can perform from that page. The PowerVault NAS Manager allows you to perform routine administrative tasks such as shutdown, restart, new share creation, and set user con-
Introduction 1-1
figuration. The PowerVault 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 PowerVault NAS
Manager to perform tasks not available directly through the PowerVault NAS Man-
ager. See “Advanced Features” found later in this document for more information.
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 PowerVault NAS Manager to set passwords, local users, shares, and so on.
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, your system automatically configures the network settings.
•
If DHCP is not installed, you can configure your system using a serial connection or the PowerVault Kick-Start utility.
Configuring Your System With DHCP
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 (“Dell xxxxxxx”, 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 by entering the system name in 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 browsers 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 PowerVault Kick-Start utility.
You can configure the system using the PowerVault NAS Manager. PowerVault NAS
Manager is served on port 1278 and is accessed by the URL, http://< systemname | system_ipaddress>:1278, where systemname is the
DELL< service_tag>.
In a system without a DNS server, you can use Internet Explorer to search for the default hostname of the system (“Dell xxxxxxx”, where xxxxxxx is the system’s service tag number).
Configuring Your System Without DHCP
The following sections describe how to configure your system using a serial connection or the PowerVault Kick-Start utility.

PowerVault Kick-Start Utility
The Dell PowerVault Kick-Start utility is software shipped with your system. This utility is used to define the initial network configuration of a system, which makes the system available on the network for complete configuration using the PowerVault NAS
Manager. This utility is intended for customers who have multiple systems to configure but are not using DHCP.
When a PowerVault 735N system is initially powered on, the PowerVault Kick-Start utility runs to determine whether the system has been configured. If the system is configured and an IP address has been assigned to the onboard network adapter,
PowerVault Kick-Start disables itself and will not run again on subsequent reboots. If the system is not configured and the user inserts a PowerVault Kick-Start diskette, when the system boots, the system automatically reads and applies the configuration information found on the diskette.
NOTES: The onboard network adapter must be connected to the network before you use the PowerVault Kick-Start utility.
If you boot your system without a PowerVault Kick-Start diskette and you are connected to the network, PowerVault Kick-Start will disable itself and will not run again unless you reinstall the operating system.
PowerVault Kick-Start configuration is a three-part procedure:
•
Create a PowerVault Kick-Start diskette
•
Create configuration files on the PowerVault Kick-Start diskette
1-4 System Administrator’s Guide

Managing Disk Arrays
This section describes how to configure and manage arrays with the PERC 2/DC that is included with the Dell PowerVault 735N NAS appliance. The PERC 2/DC controller is a high-performance intelligent PCI-to-SCSI host adapter with RAID capabilities.
Each channel supports SCSI data transfer rates of up to 80 megabytes (MB) per second per channel, and up to 15 devices.
Using Dell OpenManage Array Manager Software 3-3
NOTE: On each PERC 2/DC controller, you can create a maximum of 8 virtual disks.
Each virtual disk can have up to 8 hard-disk drives.
The following topics are discussed:
•
Recommended Virtual Disk Configuration
•
Creating Virtual Disks
•
Deleting Virtual Disks
•
Reconfiguring and Managing Virtual Disks
Recommended Virtual Disk Configuration
Dell recommends that each virtual disk created on your system's external SCSI enclosures contain 5 physical drives and be configured as a RAID-5 virtual disk. Virtual disks configured in this manner are optimized by the PERC 2/DC adapter to provide the best performance. Dell also recommends that you assign a global hotspare within the same enclosure for each virtual disk.
Creating Virtual Disks
The first step in configuring your system for improved system management is creating virtual disks.
NOTES: When you create virtual disks, you might want to consider how virtual disks will be deleted. Virtual disks created on the Dell PERC 2/DC 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.
To take advantage of all the system features such as Defrag and Encryption , Dell recommends using the default value of 64 kilobytes (KB) for the stripe size when creating a virtual disk.
To create a virtual disk, perform 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.
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 next screen is Select Disks and Virtual Disk Attributes .
5.
Select the disks and confirm information presented in the wizard.
NOTE: The PowerVault 735N only supports NTFS partitions. Formatting all partitions NTFS allow for advanced features only available under that file system.

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. A Rescan Disk Layout can be performed 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 Dell PERC 2/DC controller must be deleted 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.
Use the following procedure to delete virtual disks on Dell PERC 2/DC controllers.
1.
Right-click the last virtual disk that was created.
2.
Click Delete .
A confirmation dialog box appears.
3.
Click OK to continue.
The virtual disk disappears from the left pane. If the disk was not the last one created, the delete option is grayed out.

The following topics are discussed:
•
Writing a disk signature
•
Upgrading a basic disk to a dynamic disk
•
Reactivating dynamic disks
•
Merging foreign disks
Using Dell OpenManage Array Manager Software 3-11
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 disk displays an error bitmap on the icon. The Disk
Type is Unsigned Disk . If left unsigned, the disk cannot be used.
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.
NOTES: Upgrade all data disks on the system to dynamic before creating any volumes. This allows the system to support online volume extension. Even though it is possible to upgrade disks with existing volumes to dynamic, those volumes cannot be extended. Only volumes created on disks that are already dynamic can be extended.
Because of system recovery limitations, the only disk that should remain basic is the operating system disk. All other disks should be upgraded to dynamic during creation.
Upgrading a Basic Disk to a Dynamic Disk
Because only dynamic disks can be used for online volume extension, Dell recommends using Dell OpenManage 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 should be the only disk that remains 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. Dell strongly recommends that a disk not be reverted back to basic after data volumes are present.
3-12 System Administrator’s Guide

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
Dynamic disks with a foreign status are disks that have been moved from another system. You cannot reactivate a foreign disk; you must merge the disk to the system.
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, click the Disks and Volumes tab, and then click Disks and Volumes again from that page.
The Dell OpenManage Array Manager launches. The first time you start this software, an initial Dell Open Manage Array Manager window with six buttons for various tasks appears. You can close this window without selecting a task. When the window closes, the NAS Manager page is open behind it. This page has a window similar to a Windows Explorer window embedded in it. This window is labeled Dell Open Manage Array Manager .
Foreign disks will appear in the disk list and graphical views as Foreign.
2.
Right-click a foreign disk and click Merge Foreign Disks .
The Merge Foreign Disk Wizard displays.

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 Dell OpenManage Array Manager, basic volumes refer to all volumes that are not on dynamic disks. Dynamic volumes are logical volumes created from dynamic disks with Dell OpenManage Array
Manager.
In your system, all data volumes should be created on dynamic disks and so should be dynamic volumes. Only the operating system drive should remain basic because of system recovery limitations.
Checking Volume Properties
To check volume properties, perform the following steps:
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.
Formatting a Partition or Volume
To format a partition or volume, perform the following steps:
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 735N only supports NTFS partitions. Formatting all partitions as NTFS allow for advanced features only available under that file system.

Dell ActiveArchive™
support.dell.com
Dell ActiveArchive allows the creation and preservation of snapshots of the Dell
PowerVault 735N system data volumes. When using snapshots, system performance may be degraded, depending on the rate your data is changing and the number of snapshots kept for each virtual disk. Read performance of the virtual disk remains constant, regardless of the presence of snapshots. Read performance of the snapshot 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 date to the snapshot cache file, and the initial write is slower than if a snapshot is not being used.
From the Dell PowerVault 735N NAS Manager home page, click Disks and Volumes and then click ActiveArchive . Each snapshot is mounted as a volume on the file system to allow read-only access by clients. Snapshots can be created immediately, or scheduled as one time only or regularly repeated events.
This chapter provides information on the following topics:
•
Scheduled Snapshots
•
Adding Snapshots to the Schedule
•
Deleting a Snapshot Schedule
•
Editing the Properties of a Snapshot’s Schedule

Scheduled Snapshots
When you click Disks and Volumes and then ActiveArchive , the Scheduled Snapshot page displays a list of all scheduled snapshots and associated tasks. Each scheduled snapshot is identified by the scheduled time, day, frequency, starting date, and target volume ID. Snapshots are identified by time and date, and are located in the ActiveArchive directory. The ActiveArchive directory is located in the root of each ActiveArchive volume. Only the Administrator can access the ActiveArchive
Dell ActiveArchive™ 6-1
directory. The files and folders in the snapshot directories have the same permissions as the files and folders on the original volume. Snapshot directories are used exactly the same as conventional read-only system volumes. Unlike conventional volumes, snapshot images are static, recording the precise content of the originating volume at the time the snapshot was created.
NOTE: Do not modify the snapshot contents. Modifications to snapshot contents are not persistent.
Snapshot List
The Snapshot List displays all current active snapshots. Each entry identifies the date and time the snapshot was created and the volume it preserves. Select an individual snapshot by clicking the radio button to the left of the description.

Maximum Snapshots
This specifies the maximum number of active snapshots supported by the server, up to a maximum of 250. When the system has 250 snapshots stored, starting another snapshot will overwrite the oldest snapshot.
Dell ActiveArchive™ 6-3
Quiescent Period:
Prior to starting a snapshot, the system waits for a period of relative inactivity on the volume being imaged. The default value for this period allows systems to start an image with a consistent file set and a minimal time-out. Experienced administrators may reduce or increase this value for system optimization. Reducing the quiescent period allows snapshots 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.
Quiescent Time-Out:
Specifies the amount of time the server should wait to retry starting a snapshot. A snapshot will not start until a period of relative inactivity, specified by the Quiescent
Period , occurs. If an interval longer than Quiescent Time-Out passes before the snapshot can begin, the snapshot will not be taken.
Cache Full Warning Threshold:
Defines the percentage of cache space used that will trigger warning messages to the system event log.
Begin Snapshot Deletions:
Defines the percentage of cache space used that will trigger automatic deletion of the oldest snapshots on the system. Automatic snapshot deletions are recorded in the system log.
Cache Size:
Specifies the amount of space allocated to the cache file. Increasing this value will allow more and larger snapshots to be maintained. Ensure that adequate space is available on the snapshot files location drive.
Snapshot Files Location:
Specifies the server volume that will contain the cache data files. This file contains an exact image of all data file values that have been preserved as part of a snapshot. You should alter the default value only if the number, type, or capacity of storage disks has been altered.
NOTE: When changing the location of the snapshots files, the previous files may not be removed. To regain the space used by those files, manually delete those files from the previous location.
Snapshot Directory Name:
Specifies the directory name which will be used for the snapshot mount point. Each snapshot image appears as subdirectories of the volume which is being imaged. The entire content of the volume as it existed when the snapshot was created appears under this directory.

Network adapter teaming
•
Services for UNIX
•
File server for Macintosh
•
Services for NetWare
•
Microsoft Directory Synchronization Services

Network Adapter Teaming
Adapter teaming allows the system to use the combined throughput of network adapters in parallel to increase performance. Technologies supported by teaming are:
•
Link aggregation supports scalable bandwidth up to 800 megabits per second
(Mbps) full duplex, or up to 8 gigabits per second (Gbps) in a Gigabit Ethernet environment. Link aggregation requires support in the network interface card
(NIC) and the switch.
•
Cisco’s Fast Ether Channel (FEC) supports scalable bandwidth up to 800 Mbps at full duplex. FEC requires support in the NIC and the switch.
•
Intel’s Adaptive load balancing (ALB) offers a simple way to increase server throughput up to 400 Mbps. Outgoing server traffic is balanced automatically among as many as four network adapters. Each additional adapter adds another
100 Mbps link. Since the adapters share the existing Internet protocol (IP)
Advanced Features 7-1
address, the network does not need to be segmented or reconfigured. ALB can also be used over gigabit Ethernet links, providing throughputs up to 4 Gbps.
Intel Server Adapters also support Adapter Fault Tolerance (AFT), in which a secondary adapter backs up the link between the primary server and the switch for continued operation if the primary link fails.
Team members for the PowerVault 735N system are limited to the network connectivity of the system. Valid team members include the 10/100 megabit (Mbit) embedded NIC, optional single-port 10/100 Mbit NIC, and the optional dual-port
10/100 Mbit NIC.

User Name Mapping associates Windows and UNIX user names, which allows users to connect to NFS resources without having to log on to UNIX systems separately.
Server for Network File System (NFS)
SFU provides a robust Server for NFS that can be used to provide disk resources from your systems running Windows NT and Windows 2000 to any system on your network that supports NFS. To administer Server for NFS, set the following options from the SFU MMC console:
•
User Mapping is the name of the mapping server to use.
•
Auditing is the size and location of the logging file, and the operations to audit.
•
Locking is the grace period for locks and a list of current locks.
•
Client Groups is used to group client systems for easier setting of permissions.
Shares
You can create shares by selecting Folders and Shares in the NAS Manager. You can also select Properties in Windows Explorer and click NFS Sharing to create shares.
You can share individual directories or entire drives. You can also share directories from the command line. To share a directory, type: nfsshare sharename= Drive:Path at the command prompt.
Drive:Path is the location of the folder you want to share. As in UNIX, you cannot share a subfolder of an existing share. Each drive letter is treated as a separate root directory.

Permissions
Server for NFS uses discretionary access control lists (DACLs) to simulate typical
UNIX and NFS permissions. The default permissions are read/write for all users.
To set permissions, perform the following steps in Windows Explorer:
1.
Click Properties for the folder you are sharing.
2.
Click NFS Sharing .
3.
Click Permissions .
4.
Set the permissions.
NOTE: UNIX and Windows 2000 security models have inherently different permission sets. Any attempt to align them is only an approximation. For example, the “Take
Ownership” permission does not exist in UNIX, but in UNIX the superuser can change the ownership of any file to any user.
UNIX Utilities
UNIX utilities provided with SFU are listed in below.
Table 7-1. Categories of UNIX Utilities

Telnet Server
The telnet server works optimally for most installations. It will accept logins from a variety of clients, including the telnet clients shipped with Windows 2000,
Windows NT, Windows 95, and Windows 98, as well as a variety of character mode terminal clients from virtually any operating system. In addition, it can be configured to meet specific site requirements such as improving security, simplifying logins, and supporting stream or console mode.
Advanced Features 7-5
Authentication
The SFU telnet server supports Windows NT LAN Manager (NTLM) for authentication of client logins. NTLM allows users to be automatically authenticated to the telnet server based on their Windows NT login. This makes using telnet completely transparent to users, while ensuring that clear text passwords do not pass over the network. NTLM must be supported on the client side of the login as well, however.
When using NTLM login, users are restricted to local drives on the system they are logged in to. If they need to map network resources, they can do so by explicitly mapping with full credentials.
Administration
The telnet server is administered using the SFU MMC snap-in, or the tnadmin program.
The options available are:
•
Authentication gives you the choices of NTLM and Username/Password .
•
Auditing enables you to set event logging to a separate log file, or the Event Log, and set what events to log.
•
Server Settings enables you to set the following options:
— Maximum number of simultaneous connections
— Maximum number of failed login attempts
— Map Alt Key to CtrlA
— Telnet Port
— Mode of Operation allows you to choose Console or Stream .
— Default Domain Name is the domain name that is automatically added to the login username. The default is “.”, which disables this feature.
— Idle Session Timeout is the time until an idle session is forcibly disconnected.
— Terminate all programs when disconnecting toggles with Continue to run programs started with the command bgjob .
•
Sessions allows you to see data about the currently active sessions (such as user, domain, system, logon date/time) and either send a message to the session or terminate it.
Services For UNIX MMC Console
SFU UNIX includes a single MMC for managing all of SFU. This MMC provides a cohesive management interface that lets you administer all systems on the network from any console. Further, since SFU supports the Windows Management Interface
(WMI), management can be scripted from the command line.
7-6 System Administrator’s Guide
support.dell.com
ActiveState ActivePerl 5.6
SFU includes ActiveState's ActivePerl 5.6, a full featured port of Perl 5.6 and Perl
Script to Windows Powered operating systems. Among other improvements,
ActivePerl 5.6 includes support for fork() emulation at the interpreter level, improving the portability of scripts and modules. ActivePerl also provides full support for the
Windows Script Host, making ActivePerl an excellent tool for system administration tasks.
User Name Mapping
User Name Mapping provides mapping of names between the UNIX and Windows environments. You can perform User Name Mapping either from SFU or by clicking on
NFS on the Services page of the NAS Manager.
With User Name Mapping, you can create simple maps between Windows Powered user accounts and corresponding UNIX accounts. You can also use the Advanced Map feature to map accounts with dissimilar names. Given that UNIX user names are case sensitive, while Windows Powered operating system names are not, the use of User
Name Mapping can greatly simplify maintaining and managing accounts in the two environments. User Name Mapping uses NIS to authenticate users. Also, User Name
Mapping supports bi-directional one-to-many mapping, allowing you to map a single
UNIX or Windows Powered operating system account to multiple accounts in the other environment. For example, you can map more than one administrative account in a Windows Powered operating system to the UNIX root account.
In SFU, the Username Mapping Service and NT Authentication Service can be installed from the NAS appliance’s share, DomainUtils .
To create User and Group Name Maps, access the SFU Administration window. To access the SFU Administration window, perform the following steps:
1.
From the PowerVault 735N NAS Manager, click Maintenance .

Basic Scenarios
For UNIX and Windows NT Username Mapping, an NIS Server must already exist in the UNIX environment. Username Mapping associates NIS users and groups to
Windows NT users and groups. There are two types of maps that can be used; simple and advanced. Simple maps define a one-to-one relationship between same name users and groups. Advanced maps define a relationship between dissimilar names and groups.
Workgroup
In the Workgroup scenario, you configure Username Mapping locally on the Power-
Vault 735N system. All maps are contained on this system.
Domain
In the Domain scenario, you configure Username Mapping on the domain controller.
The Username Mapping Service and the NT Authentication Service must be installed on the Domain Controller. If multiple Domain Controllers are present, NT Authentication must be installed on each Domain Controller.
File Server for Macintosh
To configure File Server for Macintosh (FSM), access the File Server for Macintosh
Properties dialog box from the MMC.
To get to the FSM MMC Console perform the following steps:
1.
Right-click My Appliance .

Authentication
•
Microsoft Only is authentication performed via Microsoft user authentication module (UAM) only.
Advanced Features 7-9
•
Apple Clear Text is authentication performed via Apple standard clear-text UAM.
•
Apple Encrypted is authentication performed via Apple RandNum Exchange
UAM.
•
Apple Clear Text or Microsoft is authentication performed via Microsoft UAM or via Apple standard clear-text UAM.
•
Apple Encrypted or Microsoft is authentication performed via Microsoft UAM or via Apple RandNum Exchange UAM.
Microsoft UAM Volume
A UAM is a software program that prompts users for an account name and password before they log on to a server. The Macintosh Chooser has a standard UAM built in, which uses the clear-text password or Apple’s RandNum Exchange method of security.
Microsoft Authentication offers an additional level of security because the password is used as a key to encrypt a random number. If the system administrator has determined that encryption is an important security measure, you may be asked to use
Microsoft Authentication in addition to Microsoft UAM authentication.
Requirements
To use Microsoft UAM 5.0, you must have a Macintosh client running AppleShare Client 3.8 or newer or Mac OS 8.5 or newer. If you do not meet these minimum requirements, the Microsoft UAM Installer will install the old Microsoft UAM 1.0 module. If you upgrade your system software, you will need to re-run the Microsoft UAM
Installer.
Installing User Authentication
Log on to the Microsoft UAM Volume on the system to access the MS UAM file. Then drag this file to the AppleShare Folder in your System Folder.
To gain access to the Microsoft Authentication files on the system, perform the following steps:
1.

Services for NetWare
Services for NetWare (SFN) are compatible with Novell NetWare Bindery service for authentication and file access using the internetwork packet exchange/sequenced packet exchange (IPX/SPX) network protocol.
Advanced Features 7-11
Configuring the NWLink IPX/SPX Compatible Protocol
To configure this protocol, you need the internal network number, the frame type, and the network number.
Internal Network Number
Internal network numbers are used for internal routing and are generally only needed for servers. You should not need to change this option on your system.
Frame Type and Network Number
Frame types define the packet formats that are used by different networks. It is important that all systems in a network have the same frame type, so that they can communicate with the rest of the network.
When you are configuring your system, it attempts to autodetect the frame type for the client. In most cases, this is successful. However, occasionally the autodetect feature chooses an inappropriate frame type, usually because more than one frame type exists on the network. If this happens, you should manually set the frame type to match the one specified on your NetWare server. Note that if more than one frame type exists, choose the one that would be detected first. For example, if frame type
Ethernet 802.2 and Ethernet 802.3 are bound to the same segment, then configure frame type Ethernet 802.2. The order of detection is Ethernet 802.2, Ethernet 802.3,
Ethernet II, and then Ethernet SNAP.
Microsoft Directory Synchronization
Services
Microsoft Directory Synchronization Services (MSDSS) lets you synchronize a wide variety of data stored in the Active Directory service with Novell Directory Service
(NDS) and NetWare 3.
x binderies.
MSDSS is a highly flexible service that helps Novell users:
•
Adopt Windows 2000 Server and the Active Directory service.
•
Reduce directory management through two-way synchronization.
•
Migrate NDS and bindery information to Windows 2000 Server.
MSDSS supports two-way synchronization with NDS and one-way synchronization with NetWare 3.
x binderies to provide a complete directory interoperability solution.
MSDSS also supports password synchronization and provides a directory migration service.
MSDSS allows NetWare users to deploy Active Directory without having to replace existing directories or bear the cost of managing two separate directories. As a result, users have the flexibility to:
•
Consolidate directory management when multiple directories are required.
•
Manage accounts from either directory.
7-12 System Administrator’s Guide
support.dell.com
•
Use directory-enabled applications, devices, and services based on the Windows
2000 Active Directory service.
MSDSS is easy to use and makes synchronization and Active Directory setup easy through its management interface. It is fully-featured to allow users a choice of management, synchronization, and migration options.
MSDSS supports all major NetWare platforms and most Novell directories and binderies, and it includes support for IPX/SPX and TCP/IP network protocols.
Windows 2000 MSDSS Domain Controller
To implement MSDSS, you must install the Windows 2000 Server operating system and the MSDSS software (available on the Microsoft Services for NetWare version 5
CD-ROM) on at least one system. In Windows 2000, when you promote a system running Windows 2000 Server to an Active Directory server, it becomes a domain controller. You use this domain controller to configure Active Directory, to install
MSDSS, and then to import information from the existing NetWare environment.
The larger the environment, the more new servers you will need. If you are planning to have more than one domain, then you will need new hardware for the first domain controller in each domain.
You must also install Novell Client Access software on the MSDSS server or servers.
MSDSS uses Novell Client Access to authenticate and to gain access to NDS. While accessing NDS, it authenticates, but does not use a license. MSDSS also uses Novell
Client Access to map one directory’s contents to another, taking into account the fact that the object classes in Novell’s NDS or Bindery directories are different from Active
Directory object classes. Novell Client Access is also required in order to use File
Migration Utility to migrate files.
You can install Novell Client Access in four modes: IP only, IPX only, IP and IPX combined, and IP with IPX Compatibility Mode. Most NetWare environments still use IPX today. MSDSS works in all these modes because it uses Novell Client Access to access the lower layers.
If you are migrating NDS, you can import the user and group information from one
NDS server to the MSDSS server, because you have one user database per tree. You can then migrate the file system. Remember that each Novell server has its own file system, which is not replicated to other servers (whereas NDS is replicated to other servers). After the files are migrated, you can uninstall NDS from the server to free up the hardware for the Windows 2000 Server operating system.
Outline of the Deployment Procedure
The next two sections describe the procedures for implementing MSDSS in a smaller
(local area network (LAN) only) or larger (wide area network (WAN)) network. You need to adapt the guidelines to suit your environment and goals.
Advanced Features 7-13
Small Environment
A small company with a LAN-based and uncomplicated network is often a likely candidate for a quick migration. After doing all the preparations described in the above section, perform these steps (adjusted, if necessary, to your situation):
1.
Back up your NetWare system and user data.
2.
Install and configure a Windows 2000 domain controller (see the documentation that comes with your operating system software).
3.
Install the Novell Client for Windows 2000 from the Novell Web site
( http://www.novell.com/download/ ).
4.
Replace services or applications that require NDS with software compatible with
Active Directory. (NDS applications should be moved before you begin using
MSDSS, except for ZENworks, which can be replaced by IntelliMirror at any time.)
5.
Install MSDSS from the system DomainUtils share.
NOTE: To access MSDSS software, map a network drive to
\\<Dellxxxxxxx>\DomainUtils where <Dellxxxxxxx> is the name of the
Dell PowerVault 735N system.
6.
Log on to the NDS tree or bindery server as Administrator.
7.
Log on to the appropriate Windows 2000 domain as a member of the Domain
Admins group.
8.
On the MSDSS server, open the Help files, and then print out the procedures “To perform a one-time migration” and for “To migrate files.”
9.
Click the Start button and point to Programs—> Administrative Tools—>
Directory Synchronization to start MSDSS.
10. Follow the instructions as described in the Help printout “To perform a one-time migration.” The prompts will guide you through the following steps: a.
Ri ght-click MSDSS in the console tree, and then click New Session to start the New Session Wizard.
b.
Specify whether objects will be copied from NDS or Bindery.
c.
Click Migration .
d.
If you plan to migrate files as well as directory objects, click the Migrate
Files check box.
You will also run the File Migration utility.
e.
Specify the path to the Active Directory container into which you want to copy items.
f.
Accept the default domain controller in which to store the migration log .
7-14 System Administrator’s Guide
support.dell.com
g.
Specify the NDS Container or Bindery Container from which to copy items.
h.
Provide the name and password of the Novell administrative account .
i.
On the Initial Reverse Synchronization page, specify Password Options
(such as “ Set passwords to the user name .”)
When you are performing a migration, this page does not include the option to actually perform an initial reverse synchronization, but it is the page where you specify which password option you want to use.
j.
Set synchronization mode to default object mapping or to custom object mapping .
k.
If you select custom object mapping , you will be prompted to manually establish one-to-one relationships between pairs of objects.
l.
Click Finish .
After the user accounts are migrated, you can migrate the file system (migrating the users before the files allows you to migrate file-system permissions). Follow the instructions as described in the Help printout “To migrate files.” The prompts will guide you through the following steps:
•
To start the File Migration Utility click the Start button and point to Programs—>
Administrative Tools—> File Migration Utility .
•
To view mapping relationships, click View Maps .
•
To view mapped access rights for the users, groups, organization units, and organizations to be migrated, click Access Rights .
The NDS Modify right converts, by default, to Read because it does not have an equivalent NFTS right. You may wish to click the Write check box to allow
Read/Write access.
•
On the Step 2 - Security Accounts tab, verify that you are logged on with the correct Active Directory, NDS, or Bindery credentials.
•
On the Step 3 - Source and Target tab, under Source (NDS/Bindery) , click the volume or directories from which you want to migrate files. Under Target (Active
Directory) , click the shares or directories to which you want to migrate files, click the Map button, and then click Next .
If the NDS or Bindery volume you selected in the source tree indicates Unavailable , then you are not currently logged on to that tree or Bindery server. Log on, and then press <F5> after reselecting the volume to view the directories within the displayed volume.
•
On the Step 4 - Log File tab, choose your logging options and then click Next .
•
On the Step 5 - Scan tab, click Scan , and then click Next .
The utility scans all source volumes and counts and displays the number of directories and files in each. It ensures that proper access has been given to each source volume, directory, and file. If any errors occur, the utility displays them
Advanced Features 7-15
respectively under NetWare scan logs and Windows scan logs . You can select a number of acceptable errors; if this number is exceeded, the process aborts, letting you return to previous steps to correct the errors.
•
On the Step 6 - Migrate tab, click Migrate .
Manually migrate (or use third-party utilities to migrate) object security permissions and system accounts, printer objects, application objects, and other objects that
MSDSS does not migrate from Bindery or NDS to Active Directory. (MSDSS migrates
NetWare user accounts, groups, and distribution lists for Bindery and NDS, and, for
NDS only, MSDSS also migrates NDS organizational units and organizations.)
1.
Upgrade your Netware server(s) to the Windows 2000 Server or Professional operating system.
2.
On each Windows desktop in your NetWare network, uninstall Novell Client
Access.
You will configure the desktops to join the Windows 2000 domain.
3.
Optionally, upgrade NetWare clients (workstations) to the Windows 2000 Professional operating system.
4.
Configure all client systems (both Windows and non-Windows), to join the Windows 2000 domain.
Be sure the users know how to handle their password for the first time they log on (for possible password options, see “MSDSS Password Management” in
“MSDSS Deployment: Understanding Synchronization and Migration)” available on http://www.microsoft.com
.
Medium-sized or Large Environment
An organization large enough to have WAN links will probably choose either to synchronize its networks temporarily while performing a gradual migration over time (up to three months for a large network), or it will prefer to use synchronization to establish a mixed Novell/Windows 2000 network on a long-term basis. If you plan a staged migration, one-way synchronization is often the appropriate choice.
After doing all the preparation described above, perform the following steps (adjusted, if necessary, to your situation):
1.
Back up your NetWare user and system data.
2.
Install and configure a Windows 2000 domain controller (see the documentation that comes with your operating system software).
3.
Install the Novell Client for Windows 2000 from the Novell Web site http://www.novell.com/download/ .
4.
Install MSDSS from Dell PowerVault 735N system DomainUtils share.
NOTE: To access MSDSS software, map a network drive to
\\<Dellxxxxxxx>\DomainUtils where <Dellxxxxxxx> is the name of the Dell
PowerVault 735N system.
7-16 System Administrator’s Guide

5.
Log on to the NDS tree or Bindery server with administrative credentials.
6.
Log on to the appropriate Windows 2000 domain as a member of the Domain
Admins group.
7.
On the MSDSS server, open the Help files, and then print out the steps (briefly summarized below) for “To perform a one-way synchronization” or “To perform a two-way synchronization.”
8.
Click the Start button and point to Programs—> Administrative Tools—>
Directory Synchronization to start MSDSS, and let the prompts guide you through the following tasks:
•
Start the New Session Wizard (right-click MSDSS in the console tree).
•
Select Novell Bindery or Novell Directory Services (NDS) for one-way synchronization; or select Novell Directory Services (NDS) for two-way synchronization.
•
Select One-way synchronization (from Active Directory to NDS or Bindery) or select Two-way synchronization (from Active Directory to NDS and back ).
•
Specify the path to the Active Directory container into which you want to copy items.
•
Accept the default domain controller in which to store the session database .
•
Specify the NDS Container or Bindery Container from which to copy items.
•
Provide the name and password of the Novell administrative account .
•
On the Initial Reverse Synchronization page, select Perform an initial reverse synchronization .
•
Still on the Initial Reverse Synchronization page, specify Password
Options (such as “ Set passwords to the user name ”).
•
On the Object Mapping Scheme page, click Default (to accept the default mapping for each source and target directory pair), or (for NDS only) click
Custom and then Object Mapping Table (to specify objects for which you want to establish a one-to-one relationship, regardless of the object location in either directory tree). (MSDSS does not support custom object mapping for Bindery.)
•
Still on the Object Mapping Scheme page, click Filters if you want to configure a filter for this synchronization session.
•
On the Session Name page, accept the default session name or specify a new name.
•
Click Finish .
9.
If you chose one-way synchronization, you should now perform all user, group, and OU object management from Active Directory. If you established two-way synchronization, you can now manage user, group, and OU objects from either
Active Directory or NDS.
Advanced Features 7-17
10. If you plan long-term coexistence between Active Directory and NetWare, you are now finished, unless you want to migrate a subset of users, computers, and/ or files. If you plan to continue by migrating in stages from NetWare to Active
Directory, do the following in the time-frame that is convenient for you:
•
Install and configure File and Print Services for Netware (to let NetWare clients access files and printers on Windows 2000 servers) and Gateway
Services for NetWare (to let Windows clients access files and printers on
NetWare servers).
•
Replace services or applications that require NDS with commensurate software compatible with Active Directory. Do large conversions (such as
GroupWise to Exchange) as separate projects.
•
Migrate the pilot group of users and their files (adapt instructions from the
migration steps provided in the “Small Environment”section). Get the pilot
group’s feedback, and then set a schedule to migrate additional groups of users, according to the priorities you have established.
•
Migrate the rest of the users as appropriate (for example, if you migrate the set of applications they use, it is time to migrate them as well).
For further information see the Novell Web site, http://support.novell.com/servlet/
Knowledgebase and the Microsoft Windows 2000 Web site, http://www.microsoft.com/windows2000 .
Uninterruptible Power Supply (UPS)
When you are in Terminal Services Advanced Client , you can control the settings for your UPS. In Power Options on the Control Panel , the operating system includes default settings for an American Power Conversion Uninterruptible Power Supply.
The default settings are:
1.
Enable all notifications.
•
Seconds between power failure and first notification: 5
•
Seconds between subsequent power failure notifications: 120
2.
Shut down when the UPS battery is almost exhausted.
3.
Turn off the UPS.
If you are using a UPS and want to change these settings, you need to connect a keyboard, mouse, and monitor to the system. See Microsoft Windows 2000 Help for more information.
The system is configured to accept a serial connection from the UPS in serial port 2, called the UPS port in the Dell PowerVault 735N Systems Installation and Troubleshooting Guide.

Table 9-1. Troubleshooting Issues
Issue Possible cause
I cannot access my Dell
ActiveArchive from an
NFS or Macintosh Client.
Only Windows (CIFS) clients can access the snapshots stored in the
ActiveArchive folders for each volume.
I cannot take a snapshot of my volume.
I have deleted a volume and created a new one. I cannot take a snapshot of the new volume.
I have created a new basic volume but cannot take a snapshot of the volume.
XCOPY will not run on a share I've created in the root of a volume on my system.
A snapshot cannot be taken of the volume containing the snapshot cache file.
In the event that a volume is deleted and a new one is created, and they have the same drive letter, snapshots will not be active for that volume until the system has been rebooted.
After creating a basic volume, the system must be rebooted before a snapshot can be taken.
ActiveArchive is enabled.
XCOPY will not read the snapshots on a volume.
Resolution
Access ActiveArchive folders through the
Windows client to perform data recovery.
The cache file is located on the C: drive. Taking a snapshot of the C: drive is not supported.
Reboot the system. After the reboot, snapshots should work correctly for that volume.
Upgrade the volume to dynamic or reboot the system. Snapshots should be successful.
When ActiveArchive is enabled, only use XCOPY on folders and shares other than the root directory of a volume

Issue
I cannot create shares for
NetWare or Macintosh clients in PowerVault
NAS Manager.
I have just created an
HTTP share and cannot browse the directories.
I have just deleted a volume in Dell
OpenManage Array Manager and now I am unable to view my shares in NAS Manager.
In PowerVault NAS Manager, I have been modifying many shares in a short period of time and now I noticed that one of my shares is listed twice or that a share I've created is not listed.
Possible cause
NetWare and Macintosh shares can only be set up from the Advanced
Administration Menu .
Directory Browsing is not selected by default for shares that were originally created through the
Advanced Administration Menu (NetWare and
Macintosh) and are now being used for HTTP sharing.
In the event that a volume with shares is deleted, NAS Manager will not display any shares until the shares that were directed to the deleted volume are removed.
Internet Explorer stores previous versions of pages in its cache, and when that cache reaches a limit, it may start to misreport the data being sent to the shares option in NAS Manager. This can only happen if you are extensively using the sharing function in a short time period.
Resolution
Select Terminal Services Advanced Client from the PowerVault
735N NAS Manager
Maintenance menu.
Next, select Shares
Management from the
Advanced Administration Menu .
Select Terminal Services Advanced Client from the PowerVault
735N NAS Manager
Maintenance menu. Exit from the Advanced
Administration Menu and click My Appliance from the desktop.
Browse through the folders to the one being shared for HTTP (Web
Sharing). Select the check box next to Directory Browsing .
Use Terminal Services
Advanced Client to remove the shares for the deleted volume. Exit
NAS Manager and restart. Shares should be visible.
Exit from Microsoft Internet Explorer and restart, or disable page caching in Internet Explorer

Issue Possible cause
I have just added an
HTTP share but cannot see it from PowerVault
NAS Manager.
For security purposes, directory browsing is not enabled by default on an
HTTP share directed to the same folder or volume as another share for security purposes.
I am getting event errors for Macintosh.
I have just finished using
PowerVault Kick-Start and rebooted my system, but it keeps shutting down and powering off.
I inserted the Kick-Start diskette, powered on the system, and it has not powered off. Its been at least 15 to 20 minutes, what should I do?
Services for Macintosh are bound to the onboard network interface card
(NIC) by default. If this
NIC has been disabled, binding errors will occur.
You have left the
PowerVault Kick-Start diskette in the diskette drive.
Resolution
To enable directory sharing for an HTTP share, from the PowerVault NAS
Manager Maintenance page, click Terminal Services Advanced Client and modify the Web sharing properties of the folder.
If the onboard NIC is disabled using Network
Properties in the
Advanced Administration Menu , bind these services to an enabled
NIC.
Remove the diskette from the diskette drive and power on the system again.
Kick-Start takes between
5 to 10 minutes to configure from when you insert the diskette, powering on, and waiting for the system to shut itself off.
You will need to press and hold the power button to shut the system to shutdown and power off.
Once powered down, inspect your system network connection and read the rest of this troubleshooting section.

Issue
I forgot to plug in my network connection before I inserted my Kick-Start diskette and powered on.
Can I still use Kick-Start?
I finished using Kick-Start and rebooted the system, but it keeps shutting down and powering off.
Possible cause
No, power down the system by pressing and holding the power button on the front panel and connect the cable.
You have left the Kick-
Start diskette in the drive.
Resolution
You will need to connect a monitor, keyboard, and mouse, and then power on the system and log on as administrator. You will now need to set the IP address through the
Advanced Administration Menu . To do this:
1. Click once on Network
Properties in System
Settings . This will open a Network and Dial-up connections window.
2. Click Local Area Connection , scroll down and click Properties . This will open a Local Area Connection Properties window.
3. Scroll down and select
Internet Protocol (TCP/IP) then push the Properties button. This will open a new window titled Internet
Protocol (TCP/IP) Properties.
4. Enter the IP address.
5. Click OK . You will be prompted to reboot your system.
6. After you reboot, you can use the NAS Manager to set up your system.
Remove the diskette from the drive and power on the system again.

Issue Possible cause
I configured the system using Kick-Start and I cannot get to the NAS manager using a browser.
The system may not be connected to the network.
Resolution
Check to make sure that the system is connected to the network. If it is, then check to make sure that you entered a correct IP address in the
Kick-Start Application
Menu. If the problem persists, use the serial port as described in the
System Setup Placemat to access the NAS manager and check that the configuration settings were correct.
You will need to use the serial port as outlined in the System Setup Placemat.
I connected the network cable but forgot to insert the Kick-Start diskette before I powered on the system. Can I still configure my system with Kick-
Start?
No, when Kick-Start booted up it did not find a
Kick-Start diskette or a system running DHCP to obtain an IP address.
Microsoft Windows
Advanced Server assigned your system an
Autoconfiguration IP address.
The time is not properly synchronized between clients and the system.
From a Macintosh client, users cannot modify or delete a file that a
Windows client has accessed.
I just created a new volume on my system but cannot see the volume on Windows Explorer through Terminal Services .
Terminal Services will not update to show a new volume during the session in which it was created.
Make sure that clients have their time synchronized within ten minutes relative to the time zone.
Exit from Terminal Services and reconnect. The volume should now be visible.
Troubleshooting 9-5
Table 9-1. Troubleshooting Issues (continued)
Issue Possible cause
Every time I try to do a directory listing from an
NFS client on the root of a system volume, I get an error message, usually “Permission Denied”.
The problem you will experience has to do with a System Volume
Information directory, created by Microsoft
Index Server. The NFS service does not have access to this directory, and returns an error to the client when trying to list its properties.This
issue only occurs when sharing the root of a drive letter.
I cannot add a user with the name User or User1, and so on.
I have just changed the IP address of my system and now I cannot administrate it through Power-
Vault NAS Manager.
In PowerVault NAS Manager, “Cancel” doesn't seem to cancel and I've locked up the NAS Manager.
I see the following error message in the event log: “ WMI ADAP was unable to load the winspool.drv performance library due to an unknown problem within the library: 0x0 .”
Creating users with these names is not supported for security reasons.
Although the IP address changed, your local host is still trying to communicate with the system using the old IP address.
Cancel does not dynamically stop an update to the system after “OK” has been chosen. It allows the system administrator to cancel an operation before confirming it.
This is an issue with the
WDAP Performance library and is documented on Microsoft’s
Web site.
Resolution
Ignore this error. The System Volume Information directory is not used by
NFS clients or your system by default.
Do not create generic user accounts beginning with the “user”.
Close Microsoft Internet
Explorer. Re-start the
PowerVault NAS Manager.
If an operation has been performed in error, the system administrator must change the setting back manually.
Connect to the system via Terminal Services
Advanced Client and open a local command prompt. Enter the following: “ WINMGMT/
CLEARADAP ”. When the prompt returns, enter

When I am in Dell Open-
Manage Array Manager, right-clicking on a volume and selecting Explore causes the Advanced
Administration Menu to appear and the error
/e,/ idlist,:0:2628,
C:\ to display.
The Dell OpenManage
Array Manager event log has grown past its set size.
The Terminal Services session had a problem launching the Windows
Explorer console.
The Dell OpenManage
Array Manager event log size does not work.
I have noticed that my
Dell OpenManage Array
Manager Log file has exceeded it's maximum log size.
I have tried logging on to my Dell OpenManage
Remote Assistant Card
(DRAC) through the Web console software and I cannot log on. I configured my DRAC using the
PowerVault Advanced
Administration Menu and I can ping the IP address I assigned the card. What should I do?
The maximum log file size has been exceeded because the notification message can not be seen and cleared through
Terminal Services or
NAS Manager.
There are spaces before or after the user name or password entries.
Resolution
Close the Advanced
Administration Menu when the error displays and reselect Explore .
Clear the Dell OpenManage Array Manager event log periodically by rightclicking and selecting
Clear all Events from the Event tab.
Use Dell OpenManage
Array Manager to clear the logs periodically.
Reedit the configuration file to ensure there are no spaces before or after any of the user and password entries.
Troubleshooting 9-7
Table 9-1. Troubleshooting Issues (continued)
Issue Possible cause
I have just received my system and I have attached a keyboard, monitor and mouse directly to my system and I have not connected my network cable. When
I turn on the power and my system boots up, I see the system log on, open a DOS shell, run some scripts and log off the session.What is my system doing?
If you have just received your system, have not connected a network cable from a router to the network interface card as pictured in the System
Setup Placemat document, and have not configured the system using the recommended steps in the System Setup
Placemat document, the system is looking for a valid IP address, not finding one, and then logging off.
I connected the network cable but forgot to insert the PowerVault Kick-Start diskette before I powered on the system. I used PowerVault Kick-
Start to configure my system but I cannot connect to the unit.
When PowerVault Kick-
Start booted up it did not find a PowerVault Kick-
Start diskette or a system running DHCP to obtain an IP address, so the operating system assigned your system an
Autoconfiguration IP address.
Resolution
It is strongly encouraged that you use one of the three methods documented in the System
Setup Placemat to configure your system. If you must attach a keyboard, monitor, and mouse, then shut down and power off the machine by pushing and holding the power button on the front panel. You can attach a network cable from your router to your network interface card, and then power on the machine.This lets
Microsoft Windows
Advanced Server see that your system has a network connection, and then assigns an Autoconfiguration IP Address.
This allows Kick-Start to run, find a valid IP address, and then disable itself from executing.
Use the administration serial port as outlined in the System Setup Placemat document.
