2. Duo Software Installation

You should install the software for your Silicon Graphics Octane2 Duo upgrade before you install the hardware. After the software and hardware are installed, Chapter 5 provides system setup and veriﬁcation instructions.

The software installation process for the Duo upgrade consists of the following steps:

• Verifying your IRIX version

• Performing a system backup

• Backing up the Xserver ﬁle and enabling the Duo software

Note: Read any release notes included with your upgrade kit before installing the software to learn of any last minute changes.

Verifying Your IRIX Version

To verify the version of the IRIX operating system installed on your Octane2 system, follow the instructions in this section.

From an IRIX command prompt, type:

1% uname -R

You will see output similar to the following:

6.5 6.5.13f

Depending on your version, go to one of these sections: “IRIX 6.5.13 or Earlier,” “IRIX

6.5.14,” or “IRIX 6.5.15 or Later (When Available).”

007-4506-001 5

2: Duo Software Installation

IRIX 6.5.13 or Earlier

IRIX 6.5.14

If you system has IRIX version 6.5.13 or earlier, you will need to upgrade your system to IRIX 6.5.14 with patch 4426, or IRIX 6.5.15 (when available), before installing the Duo hardware. Contact your SGI representative for more information.

If you system has IRIX version 6.5.14, you will need patch 4426 before installing the Duo hardware.

To determine if you have patch 4426 installed, type the following at an IRIX command prompt:

2% versions patchSG0004426

If the output of this command is simply the headings “Name,” “Date,” and “Description” you do not have patch 4426 installed. This patch must be installed (or you must upgrade your system to IRIX 6.5.15 or later, when released) before installing the Duo hardware.

If the output of this command includes items below the Name-Date-Description heading, you do have patch 4426 installed, and you may install the Duo hardware.

IRIX 6.5.15 or Later (When Available)

If your system has IRIX version 6.5.15 or later (when available), you may install the Duo hardware.

Performing a System Backup

It is always a good idea to back up your system before installing any new hardware. If you have not backed up your system recently, take this opportunity to do so. For instructions on backing up your system, see the Personal System Administration Guide.

6 007-4506-001

Backing Up the Xserver File and Enabling Duo Software

After ensuring that you are running an appropriate version of IRIX, you must back up the original Xserver ﬁle, enable the Duo software by installing a new Xserver ﬁle, and replace the default login screen.

Follow these instructions:

1. From Toolchest > Desktop, select Open UNIX Shell.

2. Become superuser by typing su.

3. At the prompt, type:

cp /var/X11/xdm/Xserver /var/X11/xdm/Xserver.orig

4. At the prompt, type:

cp /var/X11/xdm/Xserver.2key /var/X11/xdm/Xserver

5. At the prompt, type:

chkconfig visuallogin off

6. Type exit to exit superuser mode.

7. Restart the system. The new login screen appears.

About the Option Drive

Internal SCSI devices (drives) are automatically given an address whenthey are inserted. Bus 0 (which contains the internal devices) has addresses such as 0-1, 0-2, 0-3.The system drive (the lower drive) is SCSI ID 0-1 (bus0, device1), the option drive above it (the center drive) is SCSI ID 0-2 (bus 0, device 2), and the option drive at the top of the workstation is SCSI ID 0-3 (bus 0, device 3).

Tip: To determine the total capacity and remaining space available on your disks, go to Toolchest > System > File System Manager and click the Get Info button.

Verifying an Internal Drive Installation

The workstation automatically sets up the system software for most internal devices you install and places an icon on the desktop.

Once you install the drive, follow these steps to check that the system recognizes the new drive.

1. Log in to the root account. For more information on logging in, refer to the Octane2 Workstation Owner’s Guide, “Logging In to the Octane2 Workstation,” on page 21.

2. If the device is installed correctly, you will see an icon for it on the desktop. Double-click the icon to mount the drive.

3. You can also use the System Manager to check that the drive is shown correctly.

a. Go to Toolchest > System > System Manager > Hardware and Devices > Disk

Manager. You will see a list of installed disk drives.

b. Select the drive, and click the Get Info button.

Sometimes the Desktop does not display the icon. If the drive you installed does not appear on the Desktop, try opening a UNIX shell and typing hinv. If the drive does not appear tobe installed,power off the system and make sure the drive is completely seated in the slot. Then restart the system and check the System Manager listing again.

5: Configuring the System and Verifying Installation

Adding Swap Space

The following procedure is a recommendation for creating a swap ﬁle on the second drive. Create more swap space only if you believe the swap space on the system disk is insufﬁcient and you know how much more swap space you want to add.

Note: The swap space on the system disk must have a different priority number than the swap space on the second (option) disk.

To set up additional swap space,determine the amount of swapspace on the system disk, and use that as a guideline to determine how much swap space to add.

1. Log in to the system as root.

2. Go to Toolchest > System > System Manager > System Performance > Swap Manager.

3. When the Swap Manager window appears, note the amount of swap space currently conﬁgured on the system disk (this information will be shown in the Physical column).

4. Click Add.

5. Click Next.

The Add Real Swap Space dialog box appears. (Read all the information in every dialog box.)

6. Type in your chosen amount of swap space. You may enter the same amount that was on the system disk (typically 128 MB) or you can enter a different value.

7. Select the ﬁlesystem that represents the disk to which you have chosen to add the swap ﬁle, for example, /dev/dsk/sks0d3s7.

Note: At this point you can choose to add additional swap space to either disk.

8. Click Next.

9. Click OK to conﬁrm your settings.

10. Click OK to acknowledge completion.

11. Click Close to close the Swap Manager window.

Conﬁguring Input Devices

The IRIX operating system includes support for a number of input devices. Support for additional devices can be added; see the input man page for details. This man page also contains the most current listing of supported devices.

1. Choose the serial port (1 or 2) to which you will connect the serial device for head 1.

Tip: Conﬁgurethe serial device for head 1 (the secondary head) ﬁrst. Then conﬁgure the serial device for head 0 (the primary head).

2. Use head 0 (the primary head) to do the conﬁguration. (All system administration tasks should be done from head 0.)

Conﬁguring a Serial Input Device for Head 1

1. Log in to the system on head 0 as root.

2. Go to Toolchest > System > System Manager > Hardware and Devices > Serial Device Manager. Click the Add Other button.

3. Continue the installation by reading all the information in each dialog box that appears and following the on-screen directions.

When you are done, you will have conﬁgured the device to head 0. The steps that follow reconﬁgure the device to head 1.

4. Check Table 5-1 on page 30 for the module name of the serial device you have conﬁgured.

5. From Toolchest > Desktop choose Open UNIX Shell.

6. At the prompt, type: mv /dev/input/<module name> /dev/input1/<module name>

Example: mv /dev/input/sball /dev/input1/sball.

In this example, /input/ refers to head 0, /input1/ refers to head 1, and sball to Spaceball.

7. Log out, and log in on the head for which the device was conﬁgured.

You are ﬁnished conﬁguring a serial device to head 1.

28 007-4506-001

Conﬁguring a Serial Input Device for Head 0

1. Log in to the system on head 0 as root.

2. Go to Toolchest > System > System Manager > Hardware and Devices > Serial

Device Manager. Click the Add Other button.

3. Continue the installation by reading all the information in each dialog box that

appears and following the on-screen directions.

When you are done, you will have conﬁgured the device to head 0.

4. Log out, and log in on head 0.

You are ﬁnished conﬁguring a serial device to head 0.

Listing Serial Input Devices

To get a list of the devices conﬁgured to head 0 or head 1, follow these steps:

1. From Toolchest > Desktop, select Open UNIX Shell.

Configuring Input Devices

2. For devices conﬁgured for head 0 (the primary head) at the prompt type:

cd /dev/input/

For devices conﬁgured for head 1 (the secondary head) at the prompt type:

cd /dev/input1/

3. At the prompt type ls -l .

You will see something like:

keyboard -> /hw/input/keyboard mouse -> /hw/input/mouse sball -> /hw/ttys/ttyd1

Sball is the module name for Spaceball, in this example supported on head 0 (since this was the listing for /dev/input/) and connected to serial port 1 (ttyd1).

Verifying the Memory Installation

1. Go to Toolchest > System > System Manager > About This System and check the

amount of memory listed after the Main Memory heading.

The amount of memory shown should be the total of the memory that was already in the system and the additional amount you installed. For example, if the system originally had 512 MB, and you installed two 512 MB DIMMs, the System Manager should show that you now have 1536 MB of memory.

2. If the amount of memory is incorrect, follow the directions in “Installing the

Additional System Memory” on page 11 to power off your system and remove the system module. Then check the installation as follows:

a. Check the angle of the DIMMs. They should be upright and completely seated.

b. Check that each bank is populated with two DIMMs and that they are the same

type. You must have an even number of DIMMs installed.

c. Check the color of the label on each DIMM. Both DIMMs in a bank must be of

the same size and type and must have the same colored label.

d. Continue following the directions on page 11 until the system module is

reinstalled and the system is powered back on.

Verifying the Memory Installation

3. After you have powered on the Octane2 workstation, check the amount of memory

again, as described in step 1. If the amount is still incorrect, see Chapter 7, “Troubleshooting the Duo Upgrade.”

007-4506-001 31

5: Configuring the System and Verifying Installation

Verifying the PCI Card Installation

You can verify your PCI card installation by using the hinv command.

To verify that your PCI card is recognized, follow these instructions:

1. From Toolchest > Desktop select Open UNIX Shell.

2. At the prompt, type hinv.

3. In the hardware inventory that follows, look for two lines similar to the following:

Integral Fast Ethernet: ef0, version 1 Integral Fast Ethernet: ef1, version 1

The ﬁrst line tells you that the Ethernet port on the system module is recognized. It is designated ef0. The second line gives you conﬁrmation that the PCI card (containing the second Ethernet, keyboard, and mouse ports) is recognized. This is the ef1 designation.

See Chapter 7, “Troubleshooting the Duo Upgrade,” if your Duo system is not operating properly.

Selecting the Head on Which a Program Runs

During an interactive session with the Window Manager, you can use the DISPLAY environment variable to control the head on which newly started graphics programs run. When DISPLAY is set to :0.0, programs you start run on head 0 (the primary head); when it is set to :1.0, programs you start run on head 1 (the secondary head).

For convenience, the default startup ﬁles (.login, .profile) for root and guest shells set DISPLAY to a reasonable initial value, if it is not already set. Each head has a toolchest that can be used to invoke graphics programs. Each toolchest has the DISPLAY variable in its environment set to the correct value for the head on which it appears, so any application you invoke from a toolchest inherits this DISPLAY value, and thus appears on the same head as the toolchest from which it was invoked.

Similarly, programs started by clicking an icon appear on the head from which you invoked them.

Once a program has been launched, it is not possible to move it from one head to another from the Window Manager.

Selecting the Head on Which a Program Runs

For more information on this topic, refer to Chapter 6, “Using the Octane2 Duo System,” and read the information about using Duo. Also see Appendix B, “Choosing a Graphics Head (for Developers)”.

1. Log in to the system on head 0 as root.

2. From Toolchest > Desktop, select Open a UNIX Shell.

3. At the prompt, type:

cp /var/x11/xdm/Xserver.orig /var/x11/xdm/Xserver

4. Shut down the system.

5. Unplug the second keyboard and mouse.

6. Restart the system.

6. Using the Octane2 Duo System

This chapter provides information about using the Duo system. The Octane2 workstation was designed for a single user. This chapter helps you become aware of some of the idiosyncrasies that arise when two people use the Octane2 workstation simultaneously, and provides you with instructions for speciﬁc tasks.

Be sure you have read the README ﬁle on the Duo CD that directs you to the location of the release notes. The release notes, in turn, direct you to the correct software and patches, and any other information you may need to know before using the Duo system.

When using the Duo system, keep this information in mind:

• Simultaneous use of head 0 and head 1 by users in the same login account is not

supported.

• System start up, shut down, and warning messages appear only on the primary

head, as does the System Maintenance Menu.

• When using the Toolchest > Find menu, do not use File QuickFind or Host

QuickFind, as these appear simultaneously on both the primary and secondary heads. Instead, use Toolchest > Find > Search For Files.

• If a System Administration tool launched from the desktop does not complete a

function, despite being supplied with the root password, the same application may currently be running under a second account on the Duo system.

Appendix A

A. Care and Cleaning of Compression Connectors

The Silicon Graphics Octane2 workstation uses compression connectors to connect several modules and boards to the frontplane.

A single compression connector is used in the Octane2 workstation:

• On the back of the PCI module

• On each XIO board on the XIO module

Two compression connectors are used on the system module.

The compression connector has 96 pads that enable passage of signals between the system (via the frontplane) and the system module, PCI module, or XIO board.

The compression connector has two halves: One half is located on the frontplane of the chassis; the other, on the system module, PCI module, or XIO board. Each pad on a frontplane connector is a ﬂat, gold-plated surface. Each pad on the system module, PCI module, or XIO board is composed of hundreds of tiny bristles (dendrites), as shown in Figure A-1. When a bristled pad is pressed into a gold-plated pad, a connection is created for one signal.

Bristled pad

Figure A-1 Identifying the Bristled Pad of the Compression Connector

The bristled pads may attract and hold dust, lint, grease, powder, and dirt. The presence of these substances clogs or damages the bristles and prevents them from making proper contact with the gold-plated pads on the system’s frontplane. It is important to prevent this.

007-4506-001 49

Appendix A: Care and Cleaning of Compression Connectors

Guidelines for Storing and Handling Compression Connectors

To avoid damaging a compression connector and to keep it in optimal working condition, follow these guidelines whenever the board is not installed in the chassis.

Caution: Failure to follow these instructions can result in irreparable damage to the surface of the connector’s pads, which may result in intermittent or complete failure of the product.

• Do not wipe or touch the pads of the compression connector with anything (no human ﬁngers, no brushes, no cloth, no probes), except as speciﬁed in the cleaning instructions. The bristles might be damaged.

• Whenever the module or board is not in the chassis, put the protective cap over the compression connector and put the module or board in an antistatic bag. Make sure to close (fold over) the open end of the bag to minimize exposure to dust and atmospheric gases.

• Do not put anything (not even water) onto the pads, except as speciﬁed in the cleaning instructions.

• Before laying the board on a surface, make sure that the surface is free of dust, lint, powder, metal ﬁlings, oil, water, and so on.

• Do not blow dust, dirt, or powder anywhere near the board when it is not inside its protective bag.

Guidelines for Cleaning Compression Connectors

A compression connector should never need to be cleaned if you keep the protective cover on whenever the module or board is not in the chassis. However, if the connector becomes dirty, follow the instructions below for removing pollutants.

Note: Some pollutants can irreversibly damage (corrode or chemically alter) the pad surfaces. Although cleaning may remove the pollutant, it does not repair damage incurred by this contact.

To remove pollutants, follow these instructions:

1. Obtain a can of dry compressed air or inert gas. The Envi-ro-tech Duster 1671

product manufactured by Techspray (telephone 806 372 8523) works extremely well for this application.

Caution: Do not use a cleaning product that contains any of the following ingredients: halogenated hydrocarbons, aromatic hydrocarbons, ethers, sulfur, ketones, or solvents of any kind. These substances cause irreparable damage to the connector’s surface.

2. Prepare the can for use, as instructed on the can. For example, if a tube is provided,

attach it to the can’s dispensing mechanism.

Appendix A: Care and Cleaning of Compression Connectors

Figure A-2 Spraying the Compression Connector

3. Hold the can in a vertical position.

4. Place or hold the XIO board so that the rounded edge of the compression connector faces up. Note that the rounded edge is completely closed, so that air cannot ﬂow into the connector, whereas the squared edge has an opening.

Caution: Spraying into the squared (open) edge of the connector can destroy it.

52 007-4506-001

Guidelines for Cleaning Compression Connectors

5. Position the XIO board at an angle to the can, so that the tip of the can’s applicator is

1 to 2 inches away from the ﬁrst (topmost) row of pads. Do not allow the applicator to touch the pads. When you spray, the air hits each pad and ﬂows downward.

6. Start spraying. As you spray, move the spray along the length of the connector until

the entire length has been sprayed. Move down a few rows and again spray along the entire length.

Note: Do not shake the can. Stop spraying if any visible material (for example, foam) appears. This foam will blow away once you resume spraying just air.

7. Repeat until all the pads have been sprayed.

8. When you ﬁnish, cover the compression connector with its cap or immediately

install the board in an XIO slot.

Appendix B

B. Choosing a Graphics Head (for Developers)

This appendix provides a brief overview of library routines that developers may need in order to make applications work on a Dual Head system. Formore information about the routines mentioned, see the appropriate man pages.

Note that once you open a window on a given head, the user cannot move it to the other head via the window manager; if you want users to be able to move windows from one head to another, your program must explicitly close the old window and open a new one on the other head.

Using Multiple Graphics Heads Under OpenGL, X, or Mixed-Model IRIS GL

OpenGL, X, and mixed-model IRIS GL all use X calls to choose on which screen to display; just pass the name of the desired display as the argument to XOpenDisplay(3X11). (Pass NULL as the display name if you want to default to the value of the DISPLAYenvironment variable.) You can then call RootWindow(3X11) with the newly opened display, specifying whichever screen you want; then call XCreateWindow(3X11) to create a window on the speciﬁed screen. After that, use the usual OpenGL or X calls, as appropriate, to draw or display in the window.

This is the syntax for XOpenDisplay():

Display *XOpenDisplay(display_name)

char *display_name;

007-4506-001 55

B: Choosing a Graphics Head (for Developers)

For example, use the following code example to open a window on each head of a Dual Head system:

#include <X11/Xlib.h> #include <X11/Xutil.h> #include <stdio.h>

void main(argc, argv) int argc; char **argv; {

Display *display; Window root0, root1, win0, win1;

/* Open the display specified in the DISPLAY variable. */

if ( (display = XOpenDisplay("")) == NULL )

fprintf(stderr, "%s: cannot connect to X server.\n",

/* Set up a root window for each screen. */ root0 = RootWindow(display, 0); root1 = RootWindow(display, 1);

argv[0]);

/* Now create a window on each screen. */ win0 = XCreateSimpleWindow(display, root0, 0, 0, 100,

100, 0, 0, 0);

win1 = XCreateSimpleWindow(display, root1, 0, 0, 100,

100, 0, 0, 0);

/* Display the windows and flush the output buffer. */ XMapWindow(display, win0); XMapWindow(display, win1); XFlush(display);

/* Leave them up for ten seconds before exiting. */ sleep(10);

}

56 007-4506-001

Using Multiple Heads Under IRIS GL

Under IRIS GL, you select a head on which to run a window by using the scrnselect(3G) function. If you do not call scrnselect()before opening a window using winopen(3G), the window opens on whichever screen the user has speciﬁed in the DISPLAY environment variable.

This is the syntax for scrnselect():

long scrnselect(gsnr)

long gsnr;

where gsnr is the screen number relative to the current server—that is, 0 for screen :0.0 or 1 for :1.0.

Specifying Screen Adjacency

If you include system conﬁguration ﬁles such as /usr/lib/X11/xdm/Xservers with your application, you may want to conﬁgure the layout of the heads, specifying which is on the left and which on the right. For information on how to specify adjacency, see the Xsgi man page, under the -hw option, or Chapter 2, “Duo Software Installation,” in this guide.

Appendix C

C. Cabling and Conﬁguring PCI Ethernet Boards

This appendix provides information to help you conﬁgure PCI boards in your Octane or Octane2 system and to determine how the ports on those boards will by identiﬁed by the software. Conﬁguration resources are provided in the last section of this appendix.

About the ioconfig.conf File

The ioconfig.conf ﬁle records and saves option board and port information after the option board is installed in the Octane2 workstation. However, the ﬁle reserves the board and port spaces if the option board is removed, and assigns new logical controller numbers if the same type of board is inserted in a different PCI slot.

If you want a listing of only what is currently installed, remove the ioconfig.conf ﬁle and restart your system. The ﬁle is rebuilt with information about the current hardware conﬁguration, reﬂecting what is currently installed.

Note: Rebuilding the ioconfig.conf ﬁle can change all of the maps between the logical controller numbers and the physical portlocations, depending on whether option boards have been moved to different slots or removed from the system.

Removing the ioconfig.conf File

If you need to place the PCI board (Ethernet/keyboard/mouse) in a different slot, move the board to the new slot, and then remove the ioconfig.conf ﬁle. Removing the ﬁle erases the record of the previous location so that the system does not think two boards of the same type are installed. To remove the iconfig.conf ﬁle, follow these directions:

1. From Toolchest > Desktop, choose Open UNIX Shell.

2. Become superuser by typing su

007-4506-001 59

C: Cabling and Configuring PCI Ethernet Boards

3. Type: rm /etc/ioconfig.conf

4. Type: exit to exit superuser mode.

5. Restart the system. Restarting the system builds a new ioconfig.conf ﬁle.

Mapping the Logical Controller Numbers to the Physical Port Locations

Before you can connect cables, you need to map the logical port numbers to the physical port locations. Follow these instructions:

1. From the Toolchest > Desktop, choose Open UNIX Shell.

2. At the prompt, type: cat /etc/ioconfig.conf

3. Read the following table, descriptions, and explanations to determine the correct port location(s) for the cables you wish to connect.

You see a listing similar to the following example.

Logical Controller Number Column

The Logical Controller Number is the number assigned to a port on an option board by the operating system. The logical controller numbers assigned by the operating system to a port on an option board always start higher than the last assigned port of the same type on the system module. Ports of the same type are assigned incrementing port numbers. For example, because there is one Ethernet port on the system module (which is assigned logical number 0) logical number 1 is assigned to the ﬁrst optional Ethernet port that the software sees.

Hardware, Node, and Bus Type Columns

Ignore the Hardware,Node, and Bus Type columns containing XIO entries when looking for information in this table. They appear in the ioconfig.conf ﬁle to report that hardware is being probed, on one node, using XIO at one point and PCI at another within the workstation.

Figure C-1 Physical XIO Identiﬁcation Numbers and Software Designations

Use Figure C-1 to determine the physical XIO Slot ID number. After the system module itself, the PCI module is the ﬁrst XIO module probed. Its number is 13.

In aVPro Octane2 system, the primary graphics head occupies physical quadrants A and B, but only uses the XIO connector in slot B. Its location in software is therefore XIO Slot ID 11.

62 007-4506-001

Mapping the Logical Controller Numbers to the Physical Port Locations

In a Dual Head VPro Octane2 system, the secondary graphics head occupies physical quadrants C and D, but only uses the XIO connector in slot D. Its location in software is therefore XIO Slot ID 10.

Note: Physical port numbers are assigned in XIO probing order, which starts at the highest XIO Slot ID and descends. For example, the Ethernet port on the system module (XIO Slot ID 15) will be assigned a logical number 0, before an Ethernet port on a board in the PCI module (XIO Slot ID 13) is assigned logical number 1, because XIO Slot ID 15 is probed before XIO Slot ID 13.

Table C-2 shows the XIO Slot IDs in numeric order and the device or location to which each is mapped.

Bus Type Column

The column that contains PCI entries should be read only in conjunction with the Physical XIO Slot ID column that comes before it. If the Physical XIO Slot ID number is 13, the board to which a logical controller number has been assigned is in the PCI module.

007-4506-001 63

C: Cabling and Configuring PCI Ethernet Boards

Slot ID Column

The Slot ID column refers to the physical location of the option board in the PCI module.

Again referring to the example shown in Table C-1, we see that all entries in this table have physical XIO Slot ID number 13, which means they are all in the PCI module.

We can see that the ﬁrst listing is a board in PCI slot 2 (the Slot ID column contains a 2), and that this board has one port, abbreviated scsi_ctrl (which means this is a SCSI controller port).

The second listing is a board in PCI slot 1 (the Slot ID column contains a 1). This board has one port, abbreviated rns (which, as we’ll see later, is an FDDI or CDDI port).

The third, fourth and ﬁfth listings are a single board in PCI slot 3 (the Slot ID column for all three entries contains a 3). This board has three ports, abbreviated pckb, pcms, and ef (which, as we’ll see later, are keyboard, mouse, and Ethernet ports, respectively).

Figure C-2 shows the location of each of the slots in the PCI module.
