This chapter describes how to install the software needed for the Duo configuration and provides information on system setup and verifying various hardware installations.
The information in this chapter includes:
Internal SCSI devices (drives) are automatically given an address when they 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 (bus 0, 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. |
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.
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.
If the device is installed correctly, you will see an icon for it on the desktop. Double-click the icon to mount the drive.
You can also use the System Manager to check that the drive is shown correctly.
Go to Toolchest > System > System Manager > Hardware and Devices > Disk Manager. You will see a list of installed disk drives.
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 to be 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.
For the second drive to be usable, it needs to be mounted. To mount the drive, follow these steps:
Log in to the system as root.
Go to Toolchest > System > System Manager > Hardware and Devices > Disk Manager. You will see a list of installed disk drives.
Select the drive you wish to mount, and click the Mount button.
Select a file system to mount (the default choice will usually be correct).
Click Next.
In the window that appears, type a mount point. For example, /disk2.
Click Next.
Check the box that says Let local users change filesystem contents.
Click Next.
Check the box that says Mount every time the system starts.
Click Next.
Double check the settings, and, if they look correct, click OK.
Tip: The settings will include one that says Contents of existing directory will be hidden. This refers to the contents of the directory on which the drive is being mounted (/disk2, for example), and should be fine. Click OK to close the window that reports successful completion.
Click Close to close the Disk Manager window.
Select File > Exit to exit the System Manager window.
The disk is now mounted.
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 swap space on the system disk, and use that as a guideline to determine how much swap space to add.
Log in to the system as root.
Go to Toolchest > System > System Manager > System Performance > Swap Manager.
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).
Click Add.
Click Next.
The Add Real Swap Space dialog box appears. (Read all the information in every dialog box.)
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.
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. Click Next.
Click OK to confirm your settings.
Click OK to acknowledge completion.
Click Close to close the Swap Manager window.
You are finished adding swap space.
For additional information on adding swap space, go to Toolchest > Help > Online Books > SGI Admin. See IRIX Admin: System Configuration and Operation (refer to Chapter 6, “Configuring Disk and Swap Space”) and IRIX Admin: Disks and Filesystems.
It is recommended that you place all user accounts on the second (option) disk.
To add an additional user, follow these instructions:
Log in to the system as root.
Go to Toolchest > System > System Manager > Security and Access Control.
Click the Add a User Account icon.
The dialog box appears. Read the information in this and every dialog box before proceeding.
Click Next.
Type a username for the new user.
Click Next.
Type the new user's full name.
Click Next.
Press Next to accept the Local Account default.
Choose one of the Password options.
Click Next.
If you chose to add a password, enter it now (in both boxes), then click Next.
To accept the unique, automatically generated User ID (number), click Next.
To accept the default Primary Group for the new user, click Next.
In the Home Directory window, remove the default /usr/people/username directory.
Because it is recommended that you place all users on the second (option) disk, rather than the system disk, replace the default /usr/people/username directory with the home directory of the new user on the option disk.
To do this, type the path to a location on the disk to which you wish to add the new user. For example, /disk2/username.
Select Verify and create as needed.
Click Next.
To accept the default shell program, csh, click Next.
Confirm that the settings are correct, and click OK.
You are finished adding the new user.
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.
Choose the serial port (1 or 2) to which you will connect the serial device for head 1.
Tip: Configure the serial device for head 1 (the secondary head) first. Then configure the serial device for head 0 (the primary head). Use head 0 (the primary head) to do the configuration. (All system administration tasks should be done from head 0.)
Log in to the system on head 0 as root.
Go to Toolchest > System > System Manager > Hardware and Devices > Serial Device Manager. Click the Add Other button.
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.
Check Table 5-1 for the module name of the serial device you have configured.
From Toolchest > Desktop choose Open UNIX Shell.
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.
Log out, and log in on the head for which the device was configured.
You are finished configuring a serial device to head 1.
Log in to the system on head 0 as root.
Go to Toolchest > System > System Manager > Hardware and Devices > Serial Device Manager. Click the Add Other button.
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.
Log out, and log in on head 0.
You are finished configuring a serial device to head 0.
To get a list of the devices configured to head 0 or head 1, follow these steps:
From Toolchest > Desktop, select Open UNIX Shell.
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/
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).
See Table 5-1 for the module names of supported serial devices. See the input man page for the most current listing of supported devices.
Table 5-1. Serial Devices and Their Modular Names
Device | Module Name |
|---|---|
Calcomp tablet | tablet |
Hitachi HDG-J tablets | hitachi |
Other Hitachi tablets | tablet |
Wacom tablets | wacom |
Dial box | dialbox |
Button box | dial |
Dial and button box combination | dial |
Imp infra-red presentation mouse | imp |
Logitech Magellan 3D controller | magellan |
Spaceball | sball |
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.
If the amount of memory is incorrect, follow the directions in “Installing the Additional System Memory” in Chapter 3 to power off your system and remove the system module. Then check the installation as follows:
Check the angle of the DIMMs. They should be upright and completely seated.
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.
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.
Continue following the directions on until the system module is reinstalled and the system is powered back on.
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”.
You can verify your PCI card installation by using the hinv command.
To verify that your PCI card is recognized, follow these instructions:
From Toolchest > Desktop select Open UNIX Shell.
At the prompt, type hinv.
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.
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.
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)”.
To configure your Duo system to function as a Dual Head system (that is, for both monitors to be used simultaneously by one person), follow these instructions:
Log in to the system on head 0 as root.
From Toolchest > Desktop, select Open a UNIX Shell.
At the prompt, type:
cp /var/x11/xdm/Xserver.orig /var/x11/xdm/Xserver
Shut down the system.
Unplug the second keyboard and mouse.
Restart the system.
