This procedure is broken down into four major steps:
Step 2. Initialize, Boot, and Mount the Target
The following steps prepare the target node for the installation of
Domain/OS. You back up any objects you want to save; shutdown the target;
use the partner node's calendar and invol programs to set the target's date and time and to initialize the target volume; boot the target diskless from the partner; and, finally, log in and mount the target volume on the partner's file system.
1 Back up files and directories, as necessary.
If you are installing Domain/OS on a new workstation, skip this step. If you are installing Domain/OS on an existing workstation, back up any files and directories you want to save, since initializing the disk destroys all data on it.
See "Step 2. Back Up Files" in Chapter 1 for a discussion of backup methods, a list of files and directories commonly backed-up, and suggested wbak com-mand lines for backing up the objects to removable media.
2 Make sure the target node is in NORMAL (versus SERVICE) mode.
This mode is usually controlled by a toggle switch on the back panel of the CPU. See your node's operating guide for more information.
3 Shut down the target node to the Mnemonic Debugger (MD) level.
• If the target node is running the Display Manager (DM), press the
< CMD > key and enter shut at the DM prompt:
Command: shut
You can also enter shut at the DM login prompt.
• If the target node is not running the DM, log in as root and issue the ap-propriate UNIX shutdown command at a shell prompt:
fete/shutdown -y -gO -is fete/shutdown -h now
(SysV UNIX) (BSD UNIX)
In all cases, wait for the message SHUTDOWN SUCCESSFUL and for the Mne-monic Debugger (MD) prompt to appear. The prompt depends on the node
4 Reset the target node.
To reset the node, enter the command RE (or RE W for Series 10000 work-stations), followed by a carriage return at the next prompt. For example,
> RE < RETURN>
> <RETURN>
MD7C Rev. 6.0, 1989/05/25.15:18:03
>
If the MD message does not appear after you press < RETURN> the sec-ond time, repeat the process.
5 Select the partner node as the boot device.
If the target node is connected to an Apollo Token Ring network, enter the command
> DJ N Oxax
where xax is the hexadecimal node ID of the partner node.
If the target node is connected to an ETHERNET network, enter the com-mand
> DJ E Oxax
where xax is the hexadecimal node ID of the partner node.
6 Set the target node's date, time, and time zone with the interactive calendar program.
To start calendar, enter the command
> EX CALENDAR
Respond to the series of calendar prompts. See Chapter 4 for a detailed de-scription of the prompts. Running calendar at this point ensures that the invol program creates correct Unique Identifiers (UIDs) for the objects it cre-ates on the disk.
7 When calendar completes, reset the target and select the partner node again:
> RE < RETURN>
> <RETURN>
[or RE W for Series 10000 workstations]

Installing Domain/OS Across the Network
8 Initialize the target volume and set the size of the OS paging file with the interactive invol program.
To start invol, enter the command
> EX INVOL
The main invol menu appears. If you are unfamiliar with the invol program, tum now to Chapter 3, which provides a detailed description of running invol in this context. When you finish with Chapter 3, go to step 9. If you don't use Chapter 3, use the following summarized account:
1 On the invol menu, select option 1 (ini tialize virgin physical volume) to initialize the entire disk (the typical response). Or, if you are initializing an existing disk that contains more than one logical volume, and you want to initialize and install Domain/OS on only one of the volumes, select option 3 (re-ini tialize an existing logical volume).
2 Respond to the subsequent prompts and wait for the disk initialization to complete. When asked,
Anything more to do?
enter y.
3 Select option 8 (create or modify an os paging file) on the invol menu, and respond to the subsequent prompts. Unless you have special paging size requirements, accept the default paging size. As of SR10.4, Domain/OS dynamically allocates paging file disk blocks as needed. The size you specify with invol is the initial size of the paging file, which then grows or shrinks as required.
4 When asked,
Anything more to do?
enter n.
9 Reset the target and select the partner node again:
> RE < RETURN>
> <RETURN>
[or RE W for Series 10000 workstations]
MD7C Rev. 6.0, 1989/05/25.15:18:03
> DI N Oxux
10 Run calendar again:
> EX CALENDAR
See Chapter 4 for a detailed description of the calendar prompts. Running calendar at this point sets the correct time for objects subsequently installed on the disk.
11 Reset and select the partner node again:
> RE < RETURN>
> <RETURN>
[or RE W for Series 10000 workstations]
MD7C Rev. 6.0, 1989/05/25.15:18:03
> DI N Oxxxx
12 Boot the target node from the partner node, by entering the command:
> EX DOMAIN_OS
After a series of messages, the DM login prompt appears.
13 Log in to the target node.
If the Aegis environment is not installed on the partner node, you must log in as root, since the SysV and BSD UNIX mount commands (which you'll use later in this procedure) require you to be root.
14 Mount the target volume on the partner node's file system.
The mount command you use depends on which Domain/OS environments are installed on the partner node. The UNIX SysV and BSD mount com-mands (fete/mount) require that you be logged in as root. The Aegis mount command (feom/mtvol) does not.
e In an Aegis environment enter:
/eom/mtvol {wlwx:Y} [logicaLvolume_number] /pathname where:
{wlwx:y} You enter w if the target is a Winchester disk; or wx:y if the tar-get is a Winchester disk on a Series 2500 workstation, where x is the controller number and y is the unit number.
logicaCvolume_number is the number of the logical volume you want to mount for installation. The default is 1 - you can omit this option if you initialized the target disk as a single logical volume.
Installing Domain/OS Across the Network
pathname is a unique directory pathname of your choice that becomes the mount point of the target volume (for example, target).
• In a UNIX environment enter:
mkdir /pathname
and then one of the following commands:
/etc/mount /dev/dskIWNdOsl /pathname /etc/mount /dev/wnNa /pathname where:
(SysV) (BSD)
pathname is a unique directory pathname of your choice that becomes the mount point of the target volume (for example, target).
N is the unit number of the target volume.
