Workgroup CDDI/FDDI SBus Adapter Upgrade and Configuration

Workgroup CDDI/FDDI SBus Adapter Upgrade and Configuration

This publication provides instructions for upgrading SBus adapter cards to enable diskless boot operation over the network. Instructions are provided for both SunOS 4.1.x and Solaris 2.x operating systems. The upgrade instructions include steps for configuring the firmware and upgrading SBus adapter cards.

For complete descriptions of configuration options available for the CDDI/FDDI SBus adapter, refer to the Workgroup CDDI/FDDI SBus Adapter User Guide.

Sections in this publication include the following:

Product Overview

The diskless client is any system that does not have a hard disk and relies on an assigned server for all of its resources. The diskless boot client's file systems, disk storage, and swap space are stored on a server, and it requires access to a server to boot.

Before you can begin upgrading adapter cards, you will need the following:

Note For instructions on how to copy the software to the server, see the section "Copying the SunOS Driver Files" in the chapter "Installing the Workgroup SBus Adapter Software" in the Workgroup CDDI/FDDI SBus Adapter User Guide.

Required Equipment

Make sure you have the following equipment before you begin the upgrading procedure:

Note Make sure the adapter card is plugged in to a Sun Workstation that is configured to bring up a Cisco FDDI card. Also make sure that the only adapter card in the machine is the card you want to upgrade.
Caution To prevent electrostatic discharge (ESD) wear an antistatic strap at all times when handling hardware.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic boards or components are handled improperly, can result in complete or intermittent failures. Make sure to handle the PROMs by the metal frame or carrier only; avoid touching the board (particularly avoid touching any components, connector pins, or the metal fingers on the edge connector).

Following are guidelines for preventing ESD damage:

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Configuring the Firmware

Perform the following tasks to configure the firmware:

Step 1 The latest firmware must be installed in the same directory as the driver utilities. For SunOS 4.1.x, the firmware is usually in the /usr/cfddi directory, and for Solaris 2.x, it is usually in the /opt/SBUSfddi directory. The firmware is in tar format.

Step 2 Enter the following command, where sbusxx.rom is the name of the firmware (and xx is the most current version). For example, for version 4.4, enter 44, and for version 2.7, enter 27.

Replacing the PROM

Following are the procedures for replacing the programmable read-only (PROM) devices on the SBus adapters. Make sure to follow the procedures with the numbers that correspond to the adapters you are replacing.

Replacing WA-C300T, WA-C301T, or WA-303T Adapters

Following are the steps for replacing the PROM for the WA-C300T, WA-C301T, or WA-303T adapters.

Caution To prevent ESD damage, handle adapter cards by the carrier edges only, and always use a grounding strap.

Step 1 Turn OFF power to the workstation.

Step 2 Open the workstation using the appropriate documentation.

Step 3 Remove the SBus adapter card using the appropriate documentation.

Step 4 Place the removed SBus adapter card on an antistatic mat or foam.

Step 5 Locate the PROM in socket U3. Note the orientation of the notch on the existing PROM so that you can install the new PROM with the same orientation. (See Figure 1.)


Figure 1: PROM Socket Designator for WA-C300T, WA-C301T, or WA-303T Adapters



Caution You must use a PLCC extractor to remove the PROM. (See Figure 2.) You cannot use a small flat-blade screwdriver to pry it out of the socket as with the older type of ICs. A PLCC IC does not have legs or pins that plug into the socket; instead, the contacts are on the sides of the IC and along the inner sides of the socket. When the IC is seated in the socket, the top of the IC is flush with the top of the socket. Forcing a small screwdriver or other tool between the IC and the sides of the socket to pry out the IC will damage the component or the socket or both, and you will have to replace them.

Step 6 Use a chip or PLCC-type extractor to remove the PROM labeled U3 from the PROM socket. Place the removed PROM on antistatic foam or into an antistatic bag. (See Figure 2)


Figure 2: Removing a PROM from a PLCC-Type Package



Step 7 Insert the new PROM in the same socket with the notched corner in the same orientation as the PROM you removed.

Caution Electrical damage may result if the PROM is positioned incorrectly. Always double-check the positioning of the PROM in the socket.

Step 8 After you have installed the PROM, replace the upgraded card into the workstation using the appropriate documentation.

Step 9 For the SunOS driver, extract the contents of the tar format driver diskette into a subdirectory (example: /usr/local/diskless/cfddi) on the diskless boot server, and proceed to the section "Installing the SunOS 4.1.x Diskless Boot Server Software" in this document.

For Solaris, follow the instructions in the section "Instructions for Installing the Sun Solaris 2.x Diskless Boot Server Software" in this document.


Step 10 Close the workstation using the appropriate documentation.

Step 11 Turn ON the system power.

Replacing WA-C300, WA-C301M, or WA-C303 Adapters

In general, you follow the preceding instructions to replace the PROM for the WA-C300, WA-C301M, or WA-C303 adapters. However, instead of replacing the PROM from the U3 socket, replace the PROM from the socket labeled U6. (See Figure 3.) If you are upgrading a CDDI card, you may need to remove the daughterboard to get direct access to the PROM.

Installing Solaris 2.x JumpStart

This section describes how to configure the diskless workstation and server to use the Sun Microsystems custom JumpStart utility to automatically install the Solaris software over the FDDI network. Refer to the Sun Microsystems document SPARC: Installing Solaris Software for detailed installation instructions.

Follow the instructions in the Sun document to configure the local server as an install server and/or as a boot server.

Note Confirm that the server already supports the Cisco FDDI interface.

The following procedure will not affect the kernel running on the server, but it will make changes to JumpStart files to allow Solaris installation over the FDDI.

Follow these steps to prepare the install server to perform the jumpstart installation over FDDI.

Step 1 Access the file system on the diskette from the server using either a file manager or mount the Solaris FDDI/CDDI diskette.

Step 2 Copy the SBUSfddi directory and its contents from the diskette to the install_dir_path/Solaris_2.4 directory on the server.

This will create a directory with all FDDI files and scripts in install_dir _path/Solaris_2.4/SBUSfddi.


Note Do not copy the SBUSsnmp directory and CSCOmibs directory from the diskette to the server.

Step 3 Change directories to install_dir_path/Solaris_2.4/SBUSfddi/reloc.

Step 4 Change the permission of the neti file. Enter the following:

Step 5 Enter ./neti to run the neti script. The following information appears:

Step 6 Enter y to continue with the FDDI jumpstart network installation script. The following information appears:

Step 7 At the prompt, enter the type of Sun architecture on the target workstation, either sun4m, sun4c or sun 4d. Information similar to the following appears:

Step 8 Change directories to the install_dir_path, and issue the add_an_install_client command. Following is an example:

Step 9 Refer to Chapter 4, "Preparing Custom Jumpstart Installations" in the Sun SPARC: Installing Solaris Software document for instructions on how to create the JumpStart directory and profile. Confirm that the SBUSfddi package is included in the profile. For example:

Step 10 Create a rules file following the instructions in the Sun SPARC: Installing Solaris Software document.

The server is now configured to use custom JumpStart to automatically install the Solaris software over the FDDI.


Note The installed client FDDI adapter must support diskless boot.

Step 11 At the diskless station command line, enter the following:
boot device_path -install, where the device_path is your type of workstation. See Table 1 for the proper device path.


Table  1: Diskless Workstation Device Paths
Workstation Type Device Path Notes
Sun4c /sbus/fddi
Sun4d /io-unit@f,e0200000/sbi/fddi For Solaris only
Sun4m /iommu/sbus/fddi

Following is an example of the boot device path for a Sun4m workstation:


Step 12 Once the installation is complete, the following message is displayed:

Step 13 Reboot to clear the problem or use the ifconfig command to initiate the interface.

Note At this point you may also specify netmask and broadcast addresses, if applicable.

where:


fddi#--is the FDDI adapter number. Usually fddi0.


plumb--opens the device associated with the interface.


diskless_name--is the name of the diskless workstation.


Note Other stations may not recognize the client when you issue the ifconfig commands and you don't reboot the workstation. The ARP table of other stations on the FDDI network must be flushed by deleting the old entry for the client's MAC address using the following command: arp -d diskless_name

The Solaris custom JumpStart feature configuration is complete.

Configuring the Diskless Boot Client

Perform the following steps at each diskless boot client to boot from the remote server:

Step 1 At the diskless station command line, enter boot device_path, where device_path is your type of workstation. See Table 2 for the proper device path.
