Chapter 1. Introducing PC Server 520 Features

Your PC Server 520 has an Intel Pentium microprocessor and symmetric multiprocessing (SMP) upgradability, a PCI advance bus, an integrated SCSI-2 Fast/Wide Controller, large data-storage capacity, and improved system expandability. This server is specifically designed by IBM to handle heavy file-server applications or moderate database applications in today's network environment. Using Micro Channel and peripheral component interconnect (PCI) architectures, it provides compatibility with a wide range of existing hardware and software. Super video graphics array (SVGA) support provides compatibility with many existing application programs.

Your server offers dual-processor capability through a second microprocessor connector so that you can take advantage of SMP technology. If you have an SMP-capable operating system, you can maximize the benefits of this technology,

As an open-architecture, industry-standard system, the PC Server 520 has been tested with numerous IBM and non-IBM adapters and devices to assure compatibility. Rugged dependability is achieved by incorporating quality standards and design points, such as stringent IBM systems assurance testing and a cooling design called FloThru. FloThru cooling helps keep internal electronic components of the PC Server 520 running cool to improve reliability and accommodate the full configurations necessary in today's local area network (LAN) environments.

Refer to the Setup sheet for instructions on unpacking the server and attaching cables to it.

See Chapter 2, “Installing Your Software” on page 19 for information on installing an operating system and other software. In addition, this book provides information on configuring and using the server, installing and removing options, and using the system programs that are provided. The troubleshooting information will help you solve some of the simpler problems that might occur. Appendix A in this book provides a section for you to record all the important information about your server.

About ServerGuide

It is important that you read and understand the following information, whether you choose to install an operating system that is available in the ServerGuide package or you choose to install your

own operating system. Note: The IBM ServerGuide package contains various

operating-system update programs, some of which are designed specifically for the IBM PC Server 520. Some of these updates might not be provided in existing, off-the-shelf versions of the operating systems. For this reason, if you intend to use one or more of the operating systems that are provided in the ServerGuide package, you should use ServerGuide for the installation.

You can install an operating system from ServerGuide or you can install your own operating system and still use many of the features available on ServerGuide. (For example, you can install NetFinity, which is a LAN systems-management program; run demonstration programs; use the performance-tuning feature; and do much more.) Take the time now to read the information that comes with the ServerGuide package; then return here.

The ServerGuide CDs contain small computer system interface (SCSI) and video graphics array (VGA) device drivers that will be installed automatically if you install one of the operating systems from the ServerGuide CD package. However, if you choose to install SVGA applications or your own operating system, you will need to install the SCSI device drivers and the SVGA device drivers. These device drivers are on the diskettes that come with the server. Refer to the README files on the diskettes for installation instructions.

For additional considerations regarding device drivers and operating systems, be sure to read “Hardware Considerations” on page 23, “Installing an Operating System” on page 21, and “Device Drivers” on page 33.

Installing the PeerMaster LAN Software

Some PC Server 520 models come with an IBM Ethernet Quad-BT PeerMaster Server Adapter (hereafter referred to as the PeerMaster adapter) installed as a standard feature. This section contains instructions for installing the PeerMaster LAN software provided on the IBM PeerMaster Server Adapter Option Diskette (hereafter referred to as the PeerMaster Option Diskette) that came with your server.

Before installing the LAN software, be sure your PeerMaster adapter is configured, functional, and properly cabled to your network. (For more information, see “Testing the PeerMaster Adapter” on page 146.)

Note: You must install your network operating system before you

can install the PeerMaster LAN software.

To install and configure the PeerMaster LAN software:

 If you are using OS/2 LAN Server 2.x or 3.x, continue with

“Installing PeerMaster Software for OS/2.”

 If you are using Novell NetWare 3.1x or 4.0x, go to “Installing

PeerMaster Software for Novell NetWare” on page 36.

Installing PeerMaster Software for OS/2

The installation instructions and device drivers for OS/2 LAN Server 2.x or 3.x are on the PeerMaster Option Diskette that comes with your server. The files are in the OS2 directory.

The OS2 directory includes:  A:\OS2\NDIS.TXT

The NDIS.TXT file contains the device driver installation instructions for the OS/2 LAN server. This file also describes all the files in the OS/2 and NETFINTY\OS2 directories.

Installing PeerMaster Software for Novell NetWare

This section contains the instructions to install and configure the Novell NetWare LAN software. For more information about Novell NetWare, see the documentation that came with it.

Installation Overview

The following list provides the basic flow of the LAN software installation process. The details required to install the software begin with “Precautions, Limitations, and Guidelines” on page 37.

Note: The software that comes with your PeerMaster adapter

enables multiple LAN segments to be registered with Novell NetWare as a single virtual subnetwork, hereafter called VNET. The software that creates these virtual subnetworks is a file called VNET.LAN.

 Review “Precautions, Limitations, and Guidelines” on page 37

for specific Novell NetWare information.

 Copy the LAN software onto your server's hard disk drive.

Copy the files for your PeerMaster adapter from the PeerMaster Option Diskette to the DOS partition of your server. “Installing Network Device Drivers” on page 38 guides you through this process.

 Start your server and activate the Novell NetWare operating

system at this time. “Starting Novell NetWare” on page 38 guides you through this process.

36 PC Server 520 User's Handbook for PCI/Micro Channel

Page 53

Installing PeerMaster LAN Software

 Load the PeerMaster device drivers. Two drivers are provided

for the PeerMaster adapter. One driver, MXMCA4BT.LAN, is the LAN device driver for the adapter. This driver enables the adapter to perform traditional adapter functions. The other driver, VNET.LAN, is the virtual network driver. This driver enables the PeerMaster adapter to operate in VNET Switch mode. “Loading the Network Device Drivers” on page 39 and “Sample AUTOEXEC.NCF Files” on page 50 guide you through this process.

 Update the Novell NetWare system files. Your PeerMaster

adapter is shipped with the latest versions of several Novell NetWare Loadable Modules (NLM) files. These files include fixes required for the proper operation of your PeerMaster adapter under various versions of Novell NetWare. Copy these files directly onto the Novell NetWare partition of your server. “Updating Novell NetWare System Files” on page 43 guides you through this process.

 Modify the AUTOEXEC.NCF file, if required. Update your

server startup configuration files to enable automatic loading of your PeerMaster adapter. “Loading the Network Device Drivers” on page 39 and “Sample AUTOEXEC.NCF Files” on page 50 guide you through this process.

 Read through “Unloading the Network Device Drivers” on

page 44 and “Using the Novell NetWare Monitor” on page 44.

Precautions, Limitations, and Guidelines

Review this section before you begin the Novell NetWare software installation.

 All ports within a VNET must use the same frame type.  To support various frame types across the same physical

adapters, you can load VNET.LAN multiple times. When this is done, each instance must be bound to a unique network number and include the identical grouping of adapters.

 You can include a single PeerMaster adapter in multiple VNETs

only if all of the VNETs in which you include it are comprised of the identical grouping of adapters.

Chapter 2. Installing Your Software 37

Page 54

Installing PeerMaster LAN Software

 You must configure a single PeerMaster adapter to operate

exclusively either as a VNET switch or a traditional adapter. Both modes cannot be supported simultaneously by a single adapter.

 Frame types loaded for VNET.LAN must be loaded for

MXMCA4BT.LAN.

 A newly loaded instance of VNET.LAN assumes control of all

currently active ports on each PeerMaster adapter included in the VNET. A port is considered active after MXMCA4BT.LAN is successfully loaded with the SLOT parameter value equal to the number for that port.

 To include previously inactive ports into an existing VNET, it is

necessary to unload VNET.LAN, activate the additional ports, then reload VNET.LAN. Thus, it is best to activate all ports of a PeerMaster adapter prior to loading VNET.LAN.

Installing Network Device Drivers

To install the network device drivers:

1. Insert the PeerMaster Option Diskette into drive A and change to the Novell NetWare driver directory.

CD A:\NETWARE

2. Select a target directory on the DOS partition of your server's hard disk drive, such as:

C:\NETWARE

3. Copy the contents of the driver directory on the PeerMaster Option Diskette to the target directory.

A:\NETWARE\. C:\NETWARE\.

The driver directory on your PeerMaster Option Diskette contains the Open Datalink Interface (ODI) device drivers for your adapter, the latest versions of various Novell NetWare NLM files, and several sample AUTOEXEC.NCF files.

Starting Novell NetWare

Start your Novell NetWare server at this time. If your server is running Novell NetWare 3.11:

38 PC Server 520 User's Handbook for PCI/Micro Channel

Page 55

Installing PeerMaster LAN Software

1. Manually load the system file, LSLENH.NLM.

2. Load the file from the DOS directory into which you copied the drivers from your PeerMaster Option Diskette, as follows:

:LOAD C:[PATH]\LSLENH

The power-on-self-test (POST) results appear at driver load time. POST failures typically indicate an installation or hardware problem with the adapter. For more information on POST errors, see “PeerMaster Adapter Screen Messages” on page 344.

Loading the Network Device Drivers

Your PeerMaster adapter comes with two device drivers:

 MXMCA4BT.LAN This is the base device driver for your

adapter. Once loaded and bound to a protocol, this driver enables your adapter to deliver the functions associated with traditional network adapter cards.

 VNET.LAN This device driver enables your multiport

PeerMaster adapter to be bound to a protocol, such as internetwork packet exchange (IPX), as a single subnet.

This multisegment subnet is referred to as a virtual subnet, or VNET. VNETs enable PeerMaster adapters to provide high performance Ethernet switching functions transparently under Novell NetWare.

PeerMaster adapters are high-performance, multi-port LAN adapters that can also function as an Ethernet switching hub. The manner in which you load and configure the PeerMaster adapter device drivers defines the operational characteristics of the adapter. You must take special care to properly load and configure the drivers.

This section provides three examples of the load process. The first example illustrates the driver loading procedure to configure PeerMaster adapters to operate in the Traditional Adapter mode. The second example illustrates the driver loading procedure to configure PeerMaster adapters to operate in the VNET Switch mode. The third example illustrates the driver loading procedure to configure multiple PeerMaster adapters to operate in a combination of Traditional Adapter and VNET Switch modes.

Chapter 2. Installing Your Software 39

Page 56

Installing PeerMaster LAN Software

Loading Procedure for Traditional Adapter Mode

Each PeerMaster port must be registered as a separate network segment to operate as a traditional network adapter. In this mode, the protocol stack treats each PeerMaster port as a separate PeerMaster adapter. This creates a configuration problem. Internally, Novell NetWare maps slot numbers to LAN segments. PeerMaster adapters, however, provide multiple segments per expansion slot. Thus, it becomes necessary to configure PeerMaster adapters using pseudo slot numbers to separately register the four ports on an adapter. Pseudo slot numbers are two-digit, decimal numbers, xy, where x is the expansion slot location and y is the adapter port in that slot. For example, a pseudo slot number of 23 represents port 3 of the adapter in expansion slot 2.

Most Significant Digit = Physical Slot Number

(Slot 1, 2, 3, and so forth)

Least Significant Digit = Port Number

(Port 1, 2, 3, 4)

The Port Number refers to one of the four Ethernet ports on the PeerMaster adapter.

When loading device drivers for PeerMaster adapters, use pseudo slot numbers in place of physical slot numbers. In all other respects, load drivers for PeerMaster adapters in the same manner as drivers for traditional, single-port adapters. If the SLOT keyword is not used on a load command, the driver presents a list of available pseudo slot numbers. Pseudo slot numbers already in use will not be included. The following is a typical load command.

:LOAD [PATH]MXMCA4BT.LAN SLOT=21

This command will cause Novell NetWare to load the driver for port 1 of the adapter physically installed in expansion slot 2.

For each adapter, you can issue a maximum of four load commands per frame type. NetWare loads the default frame type for each driver instance unless the FRAME keyword is used to request a specific frame type. The adapter is preconfigured with unique Ethernet media access control (MAC) addresses. Thus, there is no need to use the NODE keyword to create unique addresses for each

40 PC Server 520 User's Handbook for PCI/Micro Channel

Page 57

Installing PeerMaster LAN Software

port. You can, however, override the factory-provided MAC address using the NODE keyword.

Each time you issue the load command, Novell NetWare creates a unique instance of the LAN driver. You can use the NAME keyword to bind a unique name to each instance of the driver. You can use this unique driver name when binding a specific instance of the driver to a network protocol. The following example illustrates the use of the NAME keyword.

:LOAD D:\[PATH]MXMCA4BT.LAN SLOT=21 NAME=SLOT21 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=22 NAME=SLOT22 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=23 NAME=SLOT23 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=24 NAME=SLOT24

(where D: is the drive and PATH is the directory.)

These commands cause Novell NetWare to load one instance of the LAN driver for each LAN port of the adapter physically installed in expansion slot 2. The NAME keyword associates each driver instance with a unique name, such as slot21, slot22, and so forth.

In this mode, you must bind each driver instance to a network protocol using a unique network number. The unique driver names established using the NAME keyword bind each driver instance to a protocol. The following example illustrates the bind process.

:BIND IPX SLOT21 NET=21 :BIND IPX SLOT22 NET=22 :BIND IPX SLOT23 NET=23 :BIND IPX SLOT24 NET=24

When issuing the load command, use of the NAME keyword is optional. Alternatively, you can specify the actual driver name (MXMCA4BT.LAN) in the bind command. The bind command presents you with the list of driver instances to choose from if a specific instance is not specified. Unique driver names enable the bind process to occur without manual intervention. In this manner, you can automate the process using the AUTOEXEC.NCF file.

The process for loading multiple PeerMaster adapters is identical to the process for loading a single adapter. Load successive adapters

Chapter 2. Installing Your Software 41

Page 58

Installing PeerMaster LAN Software

in the same manner as the first, with the exception that the Most Significant Digit of the pseudo slot number is the expansion slot number of the adapter being loaded.

Loading Procedure for the VNET Switch Mode

This section describes the loading procedure for the VNET Switch mode. The first step is to load the PeerMaster adapter device driver once for each port, using the following commands:

:LOAD D:\[PATH]MXMCA4BT.LAN SLOT=21 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=22 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=23 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=24

(where D: is the drive and PATH is the directory.)

Next, load the virtual network driver (VNET.LAN). By default, the driver takes control of all loaded slots (active ports). This is performed as follows:

:LOAD [PATH]VNET.LAN

Finally, bind all of the ports to the protocol using a common network number, such as:

:BIND IPX VNET NET=2

You can load multiple instances of VNET.LAN to create multiple VNETs. The command line syntax for loading multiple VNETs is described in “Sample AUTOEXEC.NCF Files” on page 50.

Frame types, other than the default frame type, specified when loading MXMCA4BT.LAN must also be specified when loading VNET.LAN. The VNET.LAN load command will fail if the proper frame types are not specified. The following lines illustrate this requirement.

:LOAD D:\[PATH]MXMCA4BT.LAN SLOT=21 FRAME=ETHERNET_II :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=22 FRAME=ETHERNET_II :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=23 FRAME=ETHERNET_II :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=24 FRAME=ETHERNET_II

:LOAD D:\[PATH]VNET.LAN FRAME=ETHERNET_II

42 PC Server 520 User's Handbook for PCI/Micro Channel

Page 59

Installing PeerMaster LAN Software

To support packet-switching functions, PeerMaster adapters maintain an internal database containing packet-forwarding information. This table allows for 4096 entries. To prevent the overflow of this table, unused entries are aged out on a periodic basis. The default value of this aging timer is 60 seconds. If you have the need to modify the duration of the aging timer, refer to “Adjusting the Aging Timers” on page 55, for details.

Loading Combined VNETs and Traditional Networks

Various transmit and receive control blocks and buffers exist to support the PeerMaster adapter to the host bus-master interface. The number of transmit and receive packets that the interface can handle is controlled by the count of these resources. Do not adjust the count of these resources unless packets are being dropped due to lack of resources. To determine if packets have been dropped due to lack of resources, you can view the PeerMaster custom statistics using MONITOR.NLM. If you need to modify the count of these resources, see “Adjusting Transmit and Receive Resources” on page 56 for details.

Note: Specific instructions on how to create hybrid networks are

provided in “Sample AUTOEXEC.NCF Files” on page 50.

Updating Novell NetWare System Files

Your PeerMaster adapter comes with the latest versions of several Novell NetWare NLM files. These files include fixes required for the proper operation of your PeerMaster adapter under various versions of Novell NetWare. Copy these files directly onto the Novell NetWare partition of your server. The following table indicates the system files to replace.

Filename

Novell NetWare 3.11

Novell NetWare 3.12

Novell NetWare 4.01

MONITOR.NLM replace LSLENH.NLM replace MSM.NLM replace MSM31X.NLM replace replace ETHERTSM.NLM replace replace PATCHMAN.NLM replace

Chapter 2. Installing Your Software 43

Page 60

Installing PeerMaster LAN Software

You can update the system files, as follows:

1. Insert the PeerMaster Option Diskette into the diskette drive of a workstation attached to your server.

2. Compare the file dates of the NLM files on your PeerMaster Option Diskette with the dates of the same files located on the SYS:\SYSTEM directory of your server. If the specified system file does not already exist, copy it to your server. If the specified file does exist and it is an old version, replace it with the newer version provided on the PeerMaster Option Diskette.

Note: To copy a file, you might require administrator access to

your server. Some files might be restricted to read-only access. You must alter the attributes of such files to successfully overwrite them.

After you copy these system files to your server, you will no longer have to manually load system files from your DOS partition.

The installation of your PeerMaster adapter is now complete.

If you have the IBM NetFinity Services for OS/2 installed on your server, or if you want to install these services, continue with “Using NetFinity Services with Your PeerMaster Adapter” on page 58.

Unloading the Network Device Drivers

Using Novell NetWare, you can unload LAN drivers after they are loaded and operational. When both MXMCA4BT.LAN and VNET.LAN are loaded, it is important to unload VNET.LAN first, then unload MXMCA4BT.LAN. When you unload either driver, all ports controlled by the driver will become unbound from the protocol stack. Specific instances of the driver can not be selectively unloaded.

Using the Novell NetWare Monitor

The Novell NetWare MONITOR.NLM provides custom statistics for VNET.LAN and MXMCA4BT.

44 PC Server 520 User's Handbook for PCI/Micro Channel

Page 61

Installing PeerMaster LAN Software

Custom Statistics for VNET.LAN: You can display custom

statistics for VNET.LAN using MONITOR.NLM. You can select a specific instance of VNET.LAN when multiple instances are loaded. A specific instance of VNET.LAN can be uniquely identified by two parameters: slot number and frame type. The following sample menu items illustrate how MONITOR.NLM prompts you to select among three instances of VNET.LAN.

VNET [SLOT=41 FRAME=ETHERNET_82.2] VNET [SLOT=C FRAME=ETHERNET_82.3] VNET [SLOT=C FRAME=ETHERNET_82.2]

Note: Slot numbers do not correspond to either physical or pseudo

slot numbers. This is because a single instance of VNET.LAN might include multiple physical adapters. For this reason, VNET.LAN slot numbers are represented as bit masks. To ensure that VNET.LAN slot numbers do not conflict with physical slot numbers, the least significant eight bits of the mask are always set to zero. The upper eight bits of the mask—bits 8 through 15—represent the physical slots 1 through 8, respectively.

The following table illustrates the relationship between VNET.LAN slot numbers and physical slot numbers.

The slot number of 2100 specifies an instance of VNET.LAN that includes the PeerMaster adapters in physical slots 6 and 1. The sample slot value of 0C00 specifies a VNET.LAN including the adapters in physical slots 3 and 4. Note that multiple instances of VNET.LAN include the adapters in physical slots 3 and 4. Instances of VNET.LAN with identical slot numbers can be uniquely selected by their respective frame types.

The following list provides the custom statistics presented by VNET.LAN for each PeerMaster adapter.

 Learned Entry Discards

The total number of Forwarding Database entries, which have been or would have been learned, but have been discarded due to a lack of space to store them in the Forwarding Database.

If this counter is increasing, it indicates that the Forwarding Database is regularly becoming full. If this counter has a significant value but is not increasing, it indicates that the problem has been occurring but is not persistent.

 Peer Packets Received

The number of packets that were sent by peer adapters and have been received from the system bus interface by this PeerMaster adapter.

A packet received from the system bus interface is counted only if it is for a protocol being processed by the local switching function.

 Peer Packets Transmitted

The number of packets that were sent to peer adapters that have been transmitted to the system bus interface by this PeerMaster adapter.

A packet transmitted on the system bus interface is counted only if it is for a protocol being processed by the local switching function.

 Peer Packets Discarded

The number of valid packets begun by peer adapters and received from the system bus interface by this PeerMaster adapter, which were discarded (filtered) by the Forwarding Process.

46 PC Server 520 User's Handbook for PCI/Micro Channel

Page 63

Installing PeerMaster LAN Software

 Port n Packets Received

The number of packets that have been received by port n (where n = 1, 2, 3, or 4) from its segment.

A packet received by the port is counted only if it is for a protocol being processed by the local switching function.

 Port n Packets Transmitted

The number of packets that have been transmitted by port n (where n = 1, 2, 3, or 4) to its segment.

A packet transmitted to the port is counted only if it is for a protocol being processed by the local switching function.

 Port n Packets Discarded

The number of valid packets received by port n (where n = 1, 2, 3, or 4) from its segment which were discarded (filtered) by the switch-forwarding process.

Custom Statistics for MXMCA4BT.LAN

You can display statistics for MXMCA4BT using MONITOR.NLM. You can select a specific instance of MXMCA4BT when multiple instances are loaded. A specific instance of MXMCA4BT can be uniquely identified by two parameters: slot number and packet type. The following sample menu items illustrate how MONITOR.NLM prompts you to select among multiple instances of MXMCA4BT.

MXMCA4BT [SLOT=15 PACKET=ETHERNET_82.2] MXMCA4BT [SLOT=16 PACKET=ETHERNET_82.2] MXMCA4BT [SLOT=17 PACKET=ETHERNET_82.2] MXMCA4BT [SLOT=18 PACKET=ETHERNET_82.2]

Slot numbers appear in hex format. Slot numbers specified when loading the driver, however, must be specified in decimal format. Therefore, you must translate slot numbers from hex to decimal when loading the drivers. The above sample represents the drivers loaded with decimal slot numbers 21, 22, 23, and 24. This corresponds to ports 1, 2, 3 and 4 on the PeerMaster adapter installed in physical slot 2.

Chapter 2. Installing Your Software 47

Page 64

The following custom statistics are presented on a per-port basis:

 Bytes Received: The total number of bytes that the port

received from its segment.

 Unicast Packets Received: The total number of unicast packets

the port received port from its segment.

 Multicast Packets Received: The total number of multicast

packets that the port received from its segment.

 Broadcast Packets Received: The total number of broadcast

packets that the port received from its segment.

 Discarded Received Packets: The total number of incoming

packets the port was not able to receive from its segment due to lack of resources.

port received from its segment.

 Bytes Transmitted: The total number of bytes that the port

transmitted to its segment.

 Unicast Packets Transmitted: The total number of unicast

packets the port transmitted to its segment.

 Multicast Packets Transmitted: The total number of multicast

packets that the port transmitted to its segment.

 Broadcast Packets Transmitted: The total number of broadcast

packets that the port transmitted to its segment.

 Discarded Transmitted Packets: The total number of packets

that the port was not able to transmit to its segment due to lack of resources.

 Transmit Packets: The total number of transmissions by the

port to its segment that terminated with invalid status.

 Bus Transfer Errors: The total number of transmission errors

that occurred when transferring data between peer adapters or between the host system and a PeerMaster adapter.

 Host Transfer Errors: The total number of transmission errors

that occurred when transferring data between the host system and a PeerMaster adapter.

 Adapter Transmit Out Of Resources: The total number of

packets begun by the host system that were discarded by a PeerMaster adapter due to insufficient resources to transmit the packets.

 Firmware Version: The revision level of the operational

firmware on the PeerMaster adapter.

Generic Statistics

When operating in VNET Switch mode, PeerMaster adapters switch received packets, as needed, to other LAN segments. This creates transmit and receive statistics that alter the traditional meaning of various generic statistic counters. The following generic counters have a unique interpretation in VNET Switch mode operation.

 Total Packets Sent: The total number of packet transmissions

requested by the host ODI driver.

 Total Packets Received: The total number of packets received

by the host ODI driver.

 Total Send OK Byte Count (Low/High): The total number of

bytes sent by the host ODI driver.

 Total Received OK Byte Count (Low/High): The total number

of bytes received by the host ODI driver.

 All Ethernet-Specific Statistical Counters: This includes all

Ethernet-specific statistics, such as collisions, transmit status, receive status, and so forth. These counters contain the sum of all transmit and receive statistics resulting from both the host ODI driver and VNET Switch activities. Thus, it is possible to

Chapter 2. Installing Your Software 49

Page 66

Installing PeerMaster LAN Software

observe a value of zero for “Total Packets Sent” at the same time as a nonzero value for a transmit statistic, such as “Send OK Single Collision Count.” This combination of statistics indicates that no packets were transmitted through the host driver, and that a nonzero number of VNET Switch packets for the specified port experienced single collisions.

Sample AUTOEXEC.NCF Files

You must add the following command line to your AUTOEXEC.NCF file for NetWare 3.11.

:LOAD [PATH]LSLENH

The following sample AUTOEXEC.NCF files provide information for servers that have one, two, or three PeerMaster adapters installed.

One PeerMaster Adapter: Adding the following commands to

your AUTOEXEC.NCF file will cause your PeerMaster adapter to operate in the Traditional Adapter mode. In this mode, each port is bound to the protocol stack with a unique network number. Your adapter will not be able to switch packets between segments. Cross-segment traffic, if any, must be routed by your server's microprocessor.

:LOAD D:\[PATH]MXMCA4BT.LAN SLOT=21 NAME=SLOT21 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=22 NAME=SLOT22 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=23 NAME=SLOT23 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=24 NAME=SLOT24

(where D: is the drive and PATH is the directory.)

:BIND IPX SLOT21 NET=21 :BIND IPX SLOT22 NET=22 :BIND IPX SLOT23 NET=23 :BIND IPX SLOT24 NET=24

Two PeerMaster Adapters: Adding the following commands to

your AUTOEXEC.NCF file will cause your PeerMaster adapters to operate in the VNET Switch mode. In this mode, all ports are bound to the protocol stack with one common network number.

50 PC Server 520 User's Handbook for PCI/Micro Channel

Page 67

Installing PeerMaster LAN Software

Your PeerMaster adapters will switch packets between segments in this mode.

:LOAD D:\[PATH]MXMCA4BT.LAN SLOT=11 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=12 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=13 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=14

:LOAD D:\[PATH]MXMCA4BT.LAN SLOT=21 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=22 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=23 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=24

(where D: is the drive and PATH is the directory.)

# Create a VNET that globally includes all ports # ("include" parameter is omitted).

:LOAD D:\[PATH]VNET.LAN

:BIND IPX VNET NET=2

Three PeerMaster Adapters: Adding the following commands to

your AUTOEXEC.NCF file will cause your PeerMaster adapters to form a network that is a hybrid composed of an 8-segment virtual network (VNET) and four traditional networks. Cross-segment traffic within the 8 segments of the VNET is switched by your PeerMaster adapter. Cross-segment traffic from the VNET to a traditional network, or between traditional network segments, is routed internally by your server.

The preceding example illustrates a server with three PeerMaster adapters. The adapters are installed in expansion slots 1, 2, and 3. The adapters in slots 1 and 3 create an eight-segment VNET and are configured as network number 2. The adapter in slot 2 is loaded as a traditional adapter, and the four ports are each bound to the protocol with a unique network number. The protocol is configured to operate as if a total of five physical Ethernet segments exist. All ports controlled by VNET.LAN share the network number configured on the VNET.LAN bind command.

Installing PeerMaster LAN Software

Adding the following commands to your AUTOEXEC.NCF file will cause your PeerMaster adapters to form a network that is a hybrid composed of two 4-segment virtual networks (VNETs) and four traditional networks. Cross-segment traffic within each 4-segment VNET is switched by your PeerMaster adapters. Cross-segment traffic entering or leaving a VNET, or between traditional network segments, is routed internally by your server.

The load command for the VNET.LAN driver provides keywords that request the driver to include specific adapters into the VNET. You can load the VNET.LAN driver multiple times to create multiple VNETs. The keywords to include a specific adapter into a VNET are i1, i2, ... i6. The keyword i1 indicates a request to include the adapter in physical slot 1 into the VNET being formed, i2 indicates the adapter in slot 2, and so on. You can name each VNET separately, using the NAME keyword on the load command. Each VNET, when being bound to a protocol, must be assigned a unique network number. The following example illustrates the loading of multiple VNETs.

Installing PeerMaster LAN Software

Adjusting the Aging Timers

To support packet-switching functions, PeerMaster adapters maintain an internal database containing packet-forwarding information. This table can contain 4096 entries. To prevent the overflow of this table, unused entries are purged from the table on a periodic basis. Aging timers define the length of this period. Entries not accessed during the time specified are purged from the database.

Once purged, a destination address is treated as an unlearned address. Packets to unlearned destinations are sent out to all ports to ensure delivery of the data. When the PeerMaster adapter receives a response from the destination, the forwarding information table is updated and subsequent packets to that address are no longer sent out to all ports.

Thus, a long duration for the aging timer reduces traffic caused by unlearned destinations. A duration that is too long, however, results in unused entries remaining in the table for long periods of time. This might result in an overflow of the table. New destinations, which cannot be stored in the data base, are treated as unlearned traffic.

Use the AGE keyword to customize the aging timer to meet the specific needs of your network. This keyword specifies aging-timer values as follows:

:LOAD D:\[PATH]MXMCA4BT.LAN SLOT=11 AGE=N :LOAD D:\[PATH]VNET.LAN AGE=N

Where N specifies a duration in seconds. Thus, a value of 30 specifies a duration of 30 seconds.

Note that the keyword must be specified on the load command lines for MXMCA4BT.LAN and VNET.LAN. Use the same value on both command lines.

Minimum value of N = 1 Maximum value of N = 65535 Default value of N = 60

Chapter 2. Installing Your Software 55

Page 72

Installing PeerMaster LAN Software

Novell NetWare Servers poll idle workstations every 15 minutes. Thus, an aging duration of 30 minutes (N=1800) would safely prevent unlearned traffic due to idle workstations. In very large networks, however, a duration of this length might result in the overflow of the forwarding data base.

Adjusting Transmit and Receive Resources

The TXCOUNT keyword allows you to customize the number of transmit control blocks used to line up packets to the adapter, as follows:

:LOAD D:\[PATH]MXMCA4BT.LAN SLOT=11 TXCOUNT=nnn :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=12 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=13 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=14 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=21 TXCOUNT=nnn :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=22 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=23 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=24

:LOAD D:\[PATH]VNET.LAN TXCOUNT=nnn

(where D: is the drive and PATH is the directory.)

The parameter nnn is a 3-digit decimal number that specifies the number of control blocks. The first port that is loaded on a PeerMaster adapter sets the TXCOUNT of resources for that adapter. The TXCOUNT keyword for subsequent loads of the same adapter is ignored by the driver. The keyword must be specified on the load command lines for MXMCA4BT.LAN and VNET.LAN. The value of TXCOUNT for VNET.LAN should equal the sum of all adapters included in the VNET. For instance, the value of TXCOUNT for VNET.LAN in the above example is 40 if the values for slots 11 and 21 were each specified as 20.

56 PC Server 520 User's Handbook for PCI/Micro Channel

Page 73

Installing PeerMaster LAN Software

Minimum value of nnn = 2 Maximum value of nnn = 80 Default value of nnn = 10

The maximum value of 80 is recommended. The actual maximum might vary as a function of the configured size of the adapter memory window and the amount of available memory on the adapter. If the requested number is greater than the driver can provide, the default value will be used. Do not set TXCOUNT below

the default value of 10.

The RXCOUNT keyword allows you to customize the number of receive control blocks and host buffers used to receive packets from the adapter, as follows:

:LOAD D:\[PATH]MXMCA4BT.LAN SLOT=11 RXCOUNT=nnn :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=12 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=13 :LOAD D:\[PATH]MXMCA4BT.LAN SLOT=14

(where D: is the drive and PATH is the directory.)

The parameter nnn is a 3-digit decimal number that specifies the number of control blocks and buffers. Note that the keyword is specified only on the load command line for MXMCA4BT.LAN. The first port that is loaded on a PeerMaster adapter sets the RXCOUNT of resources for that adapter. The RXCOUNT keyword for subsequent loads of the same adapter is ignored by the device driver.

Minimum value of nnn = 2 Maximum value of nnn = 80 Default value of nnn = 10

the default value of 10.

Arranging Your Workspace

To get the most from your server, arrange both the equipment you use and your work area to suit your needs and the kind of work you do. Your comfort is of foremost importance, but light sources, air circulation, and the location of electrical outlets also can affect the way you arrange your workspace.

Comfort

Although no single working position is ideal for everyone, here are a few guidelines to help you find a position that suits you best.

Sitting in the same position for a long time can cause fatigue. A good chair can make a big difference. The backrest and seat should adjust independently and provide good support. The seat should have a curved front to relieve pressure on the thighs. Adjust the seat so that your thighs are parallel to the floor and your feet are either flat on the floor or on a footrest.

When using the keyboard, keep your forearms parallel to the floor and your wrists in a neutral, comfortable position. Try to keep a light touch on the keyboard and your hands and fingers relaxed. You can change the angle of the keyboard for maximum comfort by adjusting the position of the keyboard feet.

Viewing Distance

Lower Back Support

Seat Height

Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place the monitor at a comfortable viewing distance,

Arranging Your Workspace

usually 51 to 61 cm (20 to 24 in.), and position it so you can view it without having to twist your body. Also position other equipment you use regularly, such as the telephone or a mouse, within easy reach.

Glare and Lighting

Position the monitor to minimize glare and reflections from overhead lights, windows, and other light sources. Even reflected light from shiny surfaces can cause annoying reflections on your monitor screen. Place the monitor at right angles to windows and other light sources, when possible. Reduce overhead lighting, if necessary, by turning off lights or using lower wattage bulbs. If you install the monitor near a window, use curtains or blinds to block the sunlight. You might have to adjust the Brightness and Contrast controls on the monitor as the room lighting changes throughout the day.

Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen might be helpful. However, these filters might affect the clarity of the image on the screen; try them only after you have exhausted other methods of reducing glare.

Dust buildup compounds problems associated with glare. Remember to clean your monitor screen periodically using a soft cloth moistened with a nonabrasive liquid glass cleaner.

Air Circulation

Your server and monitor produce heat. Your server has one or more fans that pull in fresh air and force out hot air. The monitor lets hot air escape through vents. Blocking the air vents can cause overheating, which might result in a malfunction or damage. Place the server and monitor so that nothing blocks the air vents; usually, 51 mm (2 in.) of air space is sufficient. Also, make sure the vented air is not blowing on someone else.

66 PC Server 520 User's Handbook for PCI/Micro Channel

Page 83

Arranging Your Workspace

Electrical Outlets and Cable Lengths

The location of electrical outlets and the length of power cords and cables that connect to the monitor, printer, and other devices might determine the final placement of your server.

When arranging your workspace:

 Avoid the use of extension cords. When possible, plug the

server power cord directly into an electrical outlet.

 Keep power cords and cables neatly routed away from

walkways and other areas where they might get kicked accidentally.

For more information about power cords, refer to the User's Reference.

Chapter 2. Installing Your Software 67

Page 84

Installation Checklist

Important

Be sure to maintain at least 51 mm (2 in.) of space at the rear of the server to allow the server's cooling system to work properly. Blocking the air vents can cause overheating, which might result in a malfunction or permanent damage.

Your server hardware is set up, and you are ready to learn about your server. The order in which you do these tasks is up to you. Use the following checklist as a guide.

Ø Learn about your server and the system utility programs

Your server comes with utility programs to help you configure your server and troubleshoot problems.

If your server is a disk-array model, read and become familiar with Chapter 3, “Configuring the Disk Array” on page 71. Follow the instructions to back up your disk-array configuration information. If your server comes with a PeerMaster adapter, read and become familiar with Chapter 4, “Configuring the PeerMaster Adapter” on page 131.

Ø Record your identification numbers

Your server has important identification information that you will need if you have it serviced. Refer to “Record the Identification Numbers” on page 383, and record and retain this information. Be sure to record your ServerGuide License Diskette serial number in that section.

Ø Install options

If you decided earlier to delay installing your options, you might want to complete these installations now. Refer to Chapter 6, “Installing Options” on page 175 for installation instructions.

68 PC Server 520 User's Handbook for PCI/Micro Channel

Page 85

Installation Checklist

Ø Complete setting up your PC Server 520

If you need to set passwords or drive-startup sequences, or do other system setup tasks, use the procedures in Chapter 5, “Configuring Your Server” on page 147.

Ø Install SVGA and SCSI device drivers

If you installed SVGA applications, or if you did not install one of the operating systems from the ServerGuide CD package, get the SVGA and the SCSI device driver diskettes that come with your server and install these device drivers now. If your server came with a preinstalled PeerMaster or ServeRAID adapter, install the device drivers from the appropriate diskette.

These diskettes contain README files to help you install device drivers and complete your installation. Be sure to review the README files before you install the device drivers.

Ø Install option files and ServeRAID monitoring programs

Some options that you install might come with a diskette that contains device drivers, configuration files, or test programs. To install these files (after your operating system is installed), follow the instructions that come with the diskettes.

Ø Install application programs

To install application programs, follow the instructions supplied with each application program.

Ø Review your User's Reference

The User's Reference contains information about the hardware and software features and expansion capabilities of your server. This book also contains information about the microprocessors, memory, data-storage devices, video subsystems, input and output (I/O) ports, SCSI subsystem, and security. For your convenience, the User's Reference also includes a glossary and product warranty information.

Before You Begin

 Familiarize yourself with the information contained in this

chapter and the RAID (redundant array of independent disks) information in the User's Reference.

 Verify the disk-array configuration. The hard disk drives in

your disk-array model come configured as one logical drive.

– To view the disk-array configuration, go to “Viewing the

ServeRAID Configuration” on page 84.

– To create a disk array, go to “Creating a Disk Array” on

page 85.

 Backup the disk-array configuration. See “Backing Up Your

Disk-Array Configuration” on page 116.

After you configure the disk array, you can complete setup by installing your operating system (from the ServerGuide compact disc that comes with your server or from the diskettes that come with your operating system). Before you install an operating system, refer to the README file in Start Here on the ServerGuide Main CD. To install your operating system from the ServerGuide CD, refer to “Starting ServerGuide” on page 31 for instructions.

Device Drivers

The ServeRAID adapter requires the installation of device drivers. See the README file on the Device Driver/Administration and Monitoring diskette for detailed instructions.

If you install an operating system from the ServerGuide CD, the device drivers will be installed automatically. However, if you install your operating system from diskettes, you will need to install the device drivers. See the README file on the Device Driver/Administration and Monitoring diskette for installation instructions.

Monitoring the Adapter Status in a Local System

The Device Driver/Administration Monitoring Program diskette provides monitoring programs that you can use to perform disk-array maintenance tasks. Because the monitoring programs reside on top of your operating system, you do not need to restart the server. Instead, you can perform tasks such as the following from your active operating system desktop:

 Select the adapter that you want to monitor.  View information about drives connected to the adapter, and

change the drive state.

 Reassign a drive to replace a defunct drive.

Some operating systems provide additional features, such as adding and deleting a logical drive. Refer to the README file on the Device Driver/Administration and Monitoring diskette for specific information and installation instructions.

Monitoring Adapter Status from a Remote System

The ServeRAID Administration and Monitoring programs support the Client/Server environment using TCP/IP on a variety of platforms. The server programs run on the system containing a ServeRAID adapter and is supported on a number of operating systems. See the README file on the Device Driver/Administration and Monitoring diskette for more information. The Client program runs in various Windows environments:

 Windows NT Server Version 3.51  Windows NT Workstation Version 3.51

 Windows 95

The Client program includes many of the functions contained in the ServeRAID configuration program. Because it resides on top of your operating system, you do not need to restart the server to add and remove capacity dynamically when creating or deleting an array. You can start the Administration and Monitoring program from your active operating system desktop.

RAID Technology

This monitoring program allows you to view the ServeRAID configuration and associated devices, reassign a drive to replace a defunct drive, create a logical drive, create an array, and delete an array.

In addition, in an array that contains only one logical drive, and the total number of logical drives in all arrays is less than 7, you can change the logical drive RAID level from level 0 to level 5 (or level 5 to level 0).

See the README file on the Device Driver/Administration and Monitoring diskette for instructions on installing and using this monitoring utility.

RAID Technology

RAID is the technology of grouping several hard disk drives in a server into an array that can be defined as a single logical drive. This logical drive then appears to the operating system as a single physical drive. This grouping technique greatly enhances logical-drive capacity and performance. In addition, if one of the hard-disk drives fails (becomes defunct) the system continues to run, with no operator intervention required, at reduced performance. You can replace the defunct drive without turning off the server (hot-swap). For more information about hot-swappable hard disk drives, see “Installing a Drive in Bank C” on page 235.

Hard Disk Drive Capacities

With a server, it is important to understand the implications of hard disk drive capacities and how they influence the way you create disk arrays.

Although the drives in the disk array can be of different capacities (for example, 1 GB or 2 GB), they are treated in the disk array configuration as if they all have the capacity of the smallest disk drive. Therefore, if you have four drives of 1 GB, 1 GB, 1 GB, and 2 GB grouped in one disk array, the total capacity of the array is 1 GB times 4, or 4 GB (instead of the 5 GB physically available).

Notes:

1. The total capacity of the array without protection would be 4 GB. With RAID level 5, the usable data capacity would be 3 GB.

2. 1 GB is approximately 1 000 000000 bytes.

Additional Storage Capacity

With the Administration and Monitoring program Remote Monitor, you can dynamically add capacity to your server by defining additional arrays and logical drives (when your operating system supports this). When you use the Remote Monitor, you do not have to restart the server to create an array.

When you add hard disk drives to your server, you must configure a new disk array before you can use the drives. You can either reconfigure the existing disk array to include the capacity offered with the added drives, or group the added drives into their own array (see “Creating a Disk Array” on page 85). You also can create an array with only one drive.

The ServeRAID Configuration Program Screens

When you configure your disk array, or even just view its configuration, you will be using the IBM ServeRAID configuration program on the IBM PC ServeRAID Adapter Configuration Diskette (also called the ServeRAID Adapter Configuration Diskette). The following figure is a compilation of many of the IBM ServeRAID

1. This area displays pop-ups that apply to the current menu. For example, a pop-up allows you to select the logical drive size by entering the size in megabytes; or, to accept the default value shown. Another pop-up allows you to select the RAID level you want to assign to the logical drive you are defining. When you need to confirm an action, the Confirm pop-up appears in this area.

2. You can select any of the choices that appear on the menus.

3. The Bay/Array selection list shows 15 bays for each of the adapter's three channels. For each bay that contains a drive, the list indicates the state of the physical drive and the array in which the drive is grouped. For example, in the illustration, the

78 PC Server 520 User's Handbook for PCI/Micro Channel

RAID Technology

drive in Channel 2, Bay 1, has a drive status of ONL and is a part of Array B. Selections are made from this list to determine which bays (hard disk drives) are in your arrays.

Notes:

 The Bay/Array area on the screen does not reflect the

physical configuration of the server. In your server, the default numbering for the hard disk drive bays in each bank is 1 through 6 (from left to right). See “Installing Internal Drives” on page 212 to see the physical location of the hard disk drives.

 The IDs for the hot-swappable drives are set by the

backplanes. This allows you to define the IDs as low (0 to 5) or high (8 to 13). See “Setting Backplane SCSI ID Jumpers (J12)” on page 274 for information on setting the jumpers on the backplanes.

One channel on the ServeRAID adapter can support two daisy-chained banks of bays. The SCSI ID jumpers on the backplanes must be set to avoid SCSI ID conflicts.

 The Bay Number corresponds to the SCSI ID of the

device plus 1. When the SCSI IDs are set to high, the hard disk drive with SCSI ID 8 is installed in the leftmost bay; its status displays in Bay Number 9.

4. The Array list indicates the array ID and the size (in megabytes) of the array. When a drive is being rebuilt, this area, along with the Logical Drive list area, shows the progression of the rebuilding process.

5. The Logical Drive list identifies the logical drive (for example, A1), including its size, the RAID level, date of creation, and its write policy.

The status of the logical drive also is shown. OKY means that no problem conditions are associated with the drive. CRT means that you must replace the defunct drive and do a rebuild operation. (You will have received a message telling you what has happened to the drive.) OFL means that the logical drive is irrecoverable; the data in that drive is lost.

Chapter 3. Configuring the Disk Array 79

Page 96

Starting the ServeRAID Configuration Program

When a drive is being rebuilt, this area, along with the Array list area, shows the progression of the rebuilding process.

During an initialization process, the Write Policy area displays the percent initialized; during a synchronization process, it displays the percent synchronized.

6. The information area tells you the action you can perform on this screen or pop-up.

Starting the ServeRAID Configuration Program

You can use the Administration and Monitoring program or the ServeRAID configuration program to perform ServeRAID configuration tasks.

You can dynamically view or change the configuration of your server by using the Administration and Monitoring program from your active operating system desktop. This means that you do not have to restart the server. Refer to the README file on the Device Driver/Administration and Monitoring diskette for instructions for your operating system.

To start the ServeRAID configuration program from the ServeRAID Configuration diskette, insert the diskette into the primary diskette drive and turn on the system. If the system already is turned on, press Ctrl+Alt+Del.

During the power-on self test (POST), the ServeRAID adapter checks the configuration information on the adapter and on the hard disk drives connected to it.

 If POST does not detect problems or changes, the Main Menu

appears. See “The ServeRAID Adapter Main Menu” on page 81.

 If POST detects any change in the adapter configuration, a

configuration error message displays. See “ServeRAID Adapter POST and Setup Messages” on page 338.

 If POST detects an adapter hardware problem, an error message

displays. See “ServeRAID Adapter Status and Error Messages” on page 342.
