Chapter 1. Introducing OS/400 Integration Products for NetWare

If you are responsible for a network that includes both AS/400 and NetWare**, you will recognize the value of network integration. You may want to integrate your file and print services or user profile management and network operations. 

To aid you in managing your NetWare environment, AS/400 offers the following features: 

OS/400 Integration for Novell NetWare

OS/400 Enhanced Integration for Novell NetWare

These features allow you to combine the strengths of AS/400 application and database serving with Novell** file and print serving. You can consolidate your network by running NetWare inside AS/400 on an Integrated PC Server (also known as a file server I/O processor or FSIOP) or integrate your existing PC-based NetWare 3.12, 4.10 and 4.11 servers. 

Because you will want to use both of these features for fully-integrated NetWare Support, this book describes both, providing your reference information in just one location. 

Check out our web page at http://www.as400.ibm.com/netware for the latest information about AS/400 and NetWare, education, service and support, publications and articles, and events. 

This book uses NetWare 4.1 to refer to NetWare 4.10 and NetWare 4.11. 



 

 
OS/400 Integration for Novell NetWare (5716-SA3)

Integration for NetWare is a no-charge operating system feature that allows you to install a standard version of NetWare 4.1 on an Integrated PC Server. 

Integration for NetWare: 

  • Provides support to run a standard version of NetWare 4.1 that, with V3R7, can be installed directly from an AS/400 integrated CD-ROM. 
  • Provides file-serving support. Disk space is assigned to the server from AS/400; then partitions and volumes are created using standard NetWare utilities. 
  • Provides print-serving support. You can use NetWare print serving for your workstation or network-attached PC printers. 
  • Provides file-serving performance competitive with PC-based servers. 
  • Runs NetWare 4.1 certified NetWare Loadable Modules (NLMs) that support token-ring and Ethernet. 
  • Allows you to manage your server on AS/400 using standard NetWare utilities such as RCONSOLE from a NetWare client PC. 
  • Support for up to 16 Integrated PC Servers depending on AS/400 model. 

  • OS/400 Integration for Novell NetWare allows you to do these tasks by installing and running Novell NetWare on an Integrated PC Server. The Integrated PC Server is also known as a File Server Input/Output Processor (FSIOP) within AS/400. 

    OS/400 Enhanced Integration for Novell NetWare (5716-SS1, Feature 2246)

    OS/400 Enhanced Integration for Novell NetWare provides NetWare services for AS/400 operators and users, linking them to either PC-based or Integrated PC Server-based NetWare servers. You can simplify network user management tasks with user profile propagation, allow AS/400 users to access NetWare file systems, and send printing to NetWare-managed printers. 

    Enhanced Integration for NetWare (5716-SS1) is ordered separately as feature 2246. 

    Enhanced Integration for NetWare: 

  • Simplifies network administration with user profile and password propagation. AS/400 group or user profiles and associated information are distributed to multiple NDS** trees and NetWare 3.12 bindery services. When AS/400 users change their passwords, the change is sent to the NetWare network. 
  • Simplifies network operations by allowing you to manage NetWare user connections and disk volumes from AS/400. 
  • Keeps your network secure by authenticating each AS/400 user in NDS or the NetWare 3.12 bindery. 
  • Gives AS/400 users access to network data. Integrated file system support allows AS/400 users and applications to access files and directories in multiple NDS trees or NetWare 3.12 servers. 
  • Gives AS/400 users access to network printers. Print files are sent from an AS/400 output queue to a printer queue managed by the NetWare server. 
  • Provides integration services through a NetWare Loadable Module (NLM**) that runs on all NetWare 3.12 and 4.1 servers, whether or not you have an Integrated PC Server installed on AS/400.  

  •  

     

    Two NLMs are provided: one for NetWare 3.12 servers, the other for NetWare 4.1 servers. 

  • Connects to AS/400 using Internet Packet Exchange** (IPX**) using token-ring, Ethernet, X.25, or frame relay. 

  • Figure 1-1 illustrates an environment where an AS/400 operator is responsible for managing a network including both AS/400s and a variety of NetWare servers. 

    The network includes Integrated PC Server servers running NetWare 4.1 and PC servers running both NetWare 3.12 and NetWare 4.1. In addition, the NetWare servers control printers attached to the network. 

    In this illustration, the operator can use Enhanced Integration for NetWare to assist in managing the network, enabling integrated operations, printing, user profile management, and data security. With experience in both AS/400 and NetWare operations, the operator has the necessary skills to fully integrate this environment.

    File Serving

    You can install NetWare 4.1 on an Integrated PC Server and then use AS/400 as a file server in your NetWare network. 

    NetWare Tape Support for OS/400

      You can back up NetWare data on an Integrated PC Server to AS/400 tape drives using either the NetWare SBACKUP utility or ARCserve for NetWare from Cheyenne Software, Inc. 

    For a list of supported tape drives, check the certification bulletins at our web site http://www.as400.ibm.com/netware

    Volume Management

    From AS/400, you can manage NetWare volumes on servers across your NetWare network. This allows your AS/400 to consolidate the management of volumes associated with your NetWare network. 

    Volumes on Integrated PC Server-based servers are held in AS/400 network storage objects. These volumes can be saved to and restored from: 

  • AS/400 tape devices using NetWare SBACKUP or Cheyenne ARCserve utilities. 
  • AS/400 tape devices or save files on AS/400 using AS/400 SAV and RST commands. 
  • A LAN-based tape drive using save and restore NLMs running on the Integrated PC Server as you would do on a PC-based NetWare server. 

  • Connection Management

    For most Enhanced Integration for NetWare functions to work, you must have a connection to the server. You can automate the connection process by storing NetWare login information in authentication entries. Enrolling AS/400 users in NetWare creates and maintains authentication entries for the servers and trees in which the user has been enrolled. 

    Integrated File System

    The QNetWare file system provides access to NetWare files, directories, and NetWare Directory Services (NDS) objects through the AS/400 integrated file system (IFS). 

    You can use the QNetWare file system to: 

  • Access data stored on a local or remote Integrated PC server (Integrated PC Server) running Novell NetWare 4.1. 
  • Access data stored on PC servers running Novell NetWare 3.12 or 4.1. You can access data on these servers and Integrated PC Servers simultaneously, by using authentication entries. 
  • Access NetWare Directory Services** (NDS**) objects. 
  • Dynamically mount NetWare file systems over any local mountable file system. Flexible mount options, similar to the MAP command, simplify and speed access to NetWare files. 
  • Store data in stream files. 
  • Save and restore NetWare data. 

  • LAN-to-LAN Print

    You can print from the NetWare server on an Integrated PC Server to printers in your NetWare network using the standard NetWare print support. 

    AS/400-to-NetWare Print

    You can print from AS/400 to a NetWare printer, using the standard NetWare print support and an AS/400 remote output queue and remote writer. 

    NetWare Applications (NLMs)

    OS/400 Integration Products for NetWare supports the use of NetWare applications (NLMs) running on NetWare 4.1 on the Integrated PC Server. This support enables you to do application-serving from your AS/400 Integrated PC Server, while you centrally maintain the application on AS/400. 

    AS/400 User Enrollment

    Enhanced Integration for NetWare includes support that allows AS/400 group and user profiles to be propagated to one or more NDS trees and NetWare 3.12 servers. This allows your AS/400 to easily become a central control point for managing the group and user profiles involved in a network of NetWare servers. 

    The advantages of this support include: 

  • Central user ID administration 
  • Automatic replication of user's password changes 
  • Automatic creation of NetWare group and user objects 
  • Automatic creation of NetWare authentication entries 


  • What is an Integrated PC Server?

    The Integrated PC Server (also known as an file server I/O processor) is a dual purpose adapter, providing standard AS/400 communications over Systems Network Architecture (SNA), Transmission Control Protocol/Internet Protocol (TCP/IP), and Internetwork Packet Exchange (IPX) in addition to providing file serving. 

  • The 6506   Integrated PC Server has an Intel** 486** DX2 66 Megahertz processor that is used for file serving. This Integrated PC Server supports from 16 MB to 64 MB of memory. 

  •  

     

    Each 6506 Integrated PC Server can have a maximum of two LAN adapters. These adapters can be configured using software for either Ethernet or token ring and are sometimes referred to as ports. 

  • The 6616 Integrated PC Server has an Intel** Pentium** 166 Megahertz processor. This Integrated PC Server supports from 32 MB to 256 MB of memory.  
  • The 2850 Integrated PC Server has an Intel** Pentium** 133 Megahertz processor. This Integrated PC Server supports from 32 MB to 128 MB of memory and can only be used on AS/400 Advanced Entry.  

  •  

     

    The 6616 and 2850 Integrated PC Servers support up to two LAN adapters (or ports) in any of the following combinations: 

  • Two Ethernet ports 
  • Two token-ring ports 
  • One Ethernet port and one token-ring port 
  • One Ethernet port 
  • One token-ring port 

  • Both of these Integrated PC Servers also have one parallel and serial port. Neither of these ports are supported by NetWare for printing or communications. However, the parallel port supports a hardware license plug that is used by some NetWare NLMs. The LAN adapters for the 6616 and 2850 are separately orderable. 
    Integrated PC Server performance is enhanced with the use of an Intel** i960 (for 6506 Integrated PC Server) or a PowerPC 403 (for 2850 and 6616 Integrated PC Servers) processor and to a lesser extent, the AS/400 main central processing unit (CPU). Approximately 11 MB of memory when configuring one adapter and 14 MB of memory when configuring two adapters is not available for NetWare 4.1 to use. For example, if you use 64 MB of memory and have one adapter, NetWare has approximately 53 MB available for its use. 

    To determine the amount of disk storage you can attach and to help calculate your memory requirements, see the NetWare 4.1 Installation and Upgrade book. 

    Advantages of Using an Integrated PC Server

    The Integrated PC Server provides several advantages over adding additional PC servers to your network. These advantages can be summarized in two typical environments. 

    First, where you have an AS/400 today in a network that includes PC-based servers. Using an Integrated PC Server allows you to extend the reliability of your AS/400 into the network, using the AS/400 to hold the critical file server data in your network. You can add the advantages of AS/400 disk mirroring to your network and use AS/400 backup devices for your network data. 

    The second typical environment to consider the Integrated PC Server is where you have a smaller branch office with limited AS/400 and NetWare file serving requirements. Here the combination of NetWare and AS/400 in a single hardware package simplifies remote administration and management. Finally, you can add the integration of NetWare and the server with AS/400 IPX support, which allows for wide area network (WAN) routing. 

    Workstation Clients

    Your workstation clients can use OS/2, DOS, Windows, or any other client that is compatible with NetWare 4.1 to access the NetWare server on the Integrated PC Server. You do need a Windows 3.1 or 3.11 workstation for the initial installation of Integration for NetWare if you are installing NetWare on an Integrated PC Server. See "Novell NetWare Server" for details about the requirements for this workstation. 

    IPX Support

    IBM ships IPX as a part of OS/400. IPX allows AS/400 to act as an IPX router. 

    Integration Services for FSIOP

    Integration Services for FSIOP is a feature of OS/400 that provides the OS/2 WARP operating system for the Integrated PC Server. It allows you to install an Integrated PC Server in a system for use as a token-ring or Ethernet adapter. This support enables you to run IPX, SNA, and TCP/IP protocols on the adapter to connect two AS/400s or to link workstations to the system using Client Access/400. You can also use the adapter as part of your IPX router network. You may want to install this feature without a server or work group application to use the Integrated PC Server as a single or dual-port token-ring or Ethernet adapter. For more information on Integration Services for FSIOP, see the Integration Services for File Server I/O Processor manual. 


    Hardware and Software Requirements

    The following sections list the hardware and software necessary for installation of OS/400 Integration Products for NetWare.

  • The Integrated PC Server must have a minimum of 100 MB disk storage for the system volume. In addition, you must have storage spaces as described in Table 8-1. You will also need space for your user data. 

  •  

     

    Integration Services for FSIOP (5716-SA2) has additional disk requirements for installing the primary language version of the feature and the network server description. 

    The Integrated PC Server must be dedicated for use by NetWare 4.1; no other OS/2 products should run on it. You can install and use Enhanced Integration for NetWare on any V3R7 AS/400 model regardless of whether or not you have an Integrated PC Server installed or if you are running NetWare on an Integrated PC Server. 

    AS/400 Software Prerequisites

  • OS/400 V3R7 
  • Integration Services for FSIOP (5716-SA2) if you are installing NetWare 4.1 on an Integrated PC Server. 

  • Novell NetWare Server

    The following Novell NetWare servers are supported: 

  • NetWare 3.12 Server 

  • The NetWare 3.12 server is supported by Enhanced Integration for NetWare only and must be installed on a PC. NetWare 3.12 cannot be installed on an Integrated PC Server. Integration for NetWare does not support NetWare 3.12 servers. 
  • NetWare 4.1 Server 

  •  

     

    The NetWare 4.1 server can be installed either on a PC or an Integrated PC Server and is supported by both OS/400 Integration Products for NetWare. If you install NetWare 4.1 on an Integrated PC Server, one workstation attached to AS/400 must have the required hardware for a NetWare requester. 
    Note:
    You need a NetWare 4.1 license for every PC server and Integrated PC Server that has NetWare 4.1 installed. Integration for NetWare does not include the NetWare 4.1 license you need. You can migrate an existing license to this server or purchase a new license. 

    The following sections list the Novell NetWare server hardware requirements. 

    Hardware Requirements

  • CD-ROM drive or access to a CD-ROM image. 
  • If you install NetWare on a PC, you need one of the following communications adapter for an IPX connection to AS/400: 
  • Token-ring 
  • Ethernet 
  • X.25 (Enhanced Integration for NetWare only) 
  • Frame Relay (Enhanced Integration for NetWare only) 

  • Enhanced Integration for NetWare, feature 2246, ships two NLMs: one for NetWare 3.12 and one for NetWare 4.1 servers. Order multiple copies of Enhanced Integration for NetWare, depending on the number of servers that you intend to use with Enhanced Integration for NetWare. One license per NetWare server running the NLM is required. 

    The server requires at least 2 MB memory to run the NLM provided with Enhanced Integration for NetWare. 


    Performance and Availability Considerations

    The Integrated PC Server acts as a dual purpose adapter. This allows you to connect to the AS/400 with Client Access across IPX, SNA, and TCP/IP, in addition to providing access to your NetWare server. How the processing power of the Integrated PC Server is divided between these two tasks may affect the performance of NetWare and/or Client Access. 

    The default performance tuning setting for the Integrated PC Server is optimized for the best NetWare and Client Access performance in most customer environments. There are, however, situations where you have heavy Client Access and NetWare usage where an alternative setting may provide better performance. 

      For example, if both Client Access and NetWare usage is high, change the performance tuning to 8-10

    To change the default performance tuning setting, specify the following parameter in your AUTOEXEC.NCF file: 

      SET PERFORMANCE TUNING = X
    
    
    Changing the setting to a number between 8 and 10 reduces the performance of NetWare tasks, and increases the performance of Client Access tasks. 

    To return to the default setting, remove the parameter from your AUTOEXEC.NCF file and restart your server. 

    If you have heavy Client Access and NetWare usage, you should consider using a separate LAN adapter for your Client Access traffic. If you are adding the Integrated PC Server to a system that has a LAN adapter, you should keep your original LAN adapter(s) in place. This enables you to dedicate your Integrated PC Server to the NetWare server users. 

    Keeping a separate LAN adapter for your Client Access users can give you better availability. With both NetWare and Client Access users accessing the AS/400 via the Integrated PC Server, both sets of users are dependent on the NetWare Integrated PC Server being active. If the NetWare server "goes down" or you vary it off for some reason, the Client Access users are disconnected. Because of this, it is recommended that you dedicate a second LAN adapter to your Client Access users.
