This section provides a general overview on using operating system and initial
system loader (ISL) commands, options, and utilities to install the operating
system of a HP 3000 (Series 900) system.
CAUTION: Specific update and installation instructions are
subject to change. This section provides you with an overview of
the procedures involved. Do not use these
instructions to update your system.
For specific information on using operating system and initial
system loader (ISL) commands, options, and utilities to install
your operating system using new factory release tapes, refer to
the appropriate version of HP e3000 MPE/iX System Software
Maintenance Manual. This manual is included with the
software tapes for each new release and contains information specific
for that release.
The INSTALL utility replaces all files on the system disk
with files from the boot tape. These files include the disk logical
interface format (LIF) label and directory, the system volume label,
the bad sector table, the disk free space map, the system directory
(null directory), boot files, and all base system files.
The INSTALL utility builds a null system directory that contains the
account SYS. The groups CONFIG, DIAG, MPEXL,
and the default configuration groups are added
by the INSTALL utility later.
Installing a new version of the operating system can be accomplished
by the system manager, except where specially customized software
is to be installed. In this case, installation requires a Hewlett-Packard
Service Representative.
After completion, the default option (INSTALL START) boots the system
from disk.
The INSTALL utility is primarily used to do a first-time installation
of the MPE/iX operating system. If you are installing a new release,
be sure to follow the exact directions provided in the HP
e3000 MPE/iX System Software Maintenancen Manual.
The INSTALL utility can also be used to replace current versions
of the operating system, boot files, and base system files. Finally,
the INSTALL utility can be used as a last resort in system
recovery to reload the software.
This section begins with a description of using the INSTALL utility to
recover a lost system. The remaining
sections provide information on doing a first-time installation
or a reinstallation when the system was previously in use.
Using the INSTALL Utility to Recover a Lost System
If your system fails, you have many options to use to help recover your system.
Use the INSTALL utility as a recovery method only after doing
the following:
attempting a START RECOVERY
attempting a START NORECOVERY
ensuring the validity of your START procedure
ensuring that your hardware and hardware code, and current
software are functioning properly
attempting an update
In the event of a major system failure caused by corrupted files or other
possible causes, you can use the INSTALL utility to reload your system.
In this procedure, the system is recovered through the use of backup tapes. You
use a system load tape created as part of your system backup procedure.
Alternately, you may instead use the SLT that the AUTOINST program
created when the system was last installed or updated.
NOTE:Do not use these instructions to install your
system. They are an overview only, and not a complete listing of tasks. Please
refer to the HP e3000 MPE/iX System Software
Maintenance Manual for full instructions on installing the system.
The following is an overview of the steps to perform:
Install from the backup or AUTOINST-created SLT and start
the system.
Use VOLUTIL to initialize additional system volumes
(if any).
Restore the latest partial and full backup tapes.
Shut down the system with the SHUTDOWN command, and reboot
the system with START NORECOVERY.
The reinstallation process is now complete.
Scheduling an INSTALL
If you are using the INSTALL utility as a recovery method, the
opportunity to schedule your system's installation is probably not available to
you. Take time to thoroughly examine the INSTALL process before using
it as a recovery method. Understanding the INSTALL process can reduce
system operator and system manager error and, therefore, reduce your system's
downtime.
Normal operating system replacement should be scheduled for off-peak hours.
The INSTALL procedure can take up to five hours, depending
on your system and the number of subsystems you have purchased.
Schedule the installation immediately after a full backup, if you
are not doing a first-time installation.
Using the INSTALL Utility and Options
The command to invoke the INSTALL utility is INSTALL. The
utility has one initial option, START/NOSTART, with additional options
if START is selected.
To use INSTALL, enter the INSTALL command with or without
START/NOSTART and its options. Separate options from the INSTALL
command and other options with a space or semicolon.
Entering the command INSTALL at the ISL prompt without listing any options:
ISL> INSTALL
is the same as specifying the following default options:
The INSTALL process with its default options instructs the system to perform
the following tasks if an autoboot file exists, the autoboot file is enabled,
and the START option is specified:
Install the operating system, and autoboot the system from disk
after the installation is completed.
Use the configuration group, CONFIG.SYS.
Attempt to log on in the user account OPERATOR.SYS (if
there is no OPERATOR.SYS user, you will see the MPE prompt)
Bring up all volumes present on the system.
Allow access to all mounted volumes by all users.
Execute the commands in the system startup file,
SYSSTART.PUB.SYS, if it is present.
Installing the Operating System: a Preview
Booting the system to MPE/iX by using the INSTALL utility may involve
preliminary steps if your system has previously been in use. When installing a
system for the first time, you do not need to be concerned with these
preliminary steps discussed below.
Some of the preliminary steps include the following:
Backing up system data.
Removing users and jobs from the system.
Storing to tape any system files that you wish to maintain.
Once you are ready to begin the installation proper, the following
are required steps of the process:
Installing from the system load tape.
Restoring the FOS tape.
Restoring the SUBSYS tape.
Creating a customized system load tape.
Updating with the customized system load tape.
Restoring user files, if any.
Starting system for normal operation.
NOTE: Each customer installation is somewhat different. Examine
the processes described for areas you may need to customize to fit
your system. The following Hewlett-Packard publications will prove
useful for updating your system:
HP e3000 MPE/iX System Software Maintenance Manual
MPE/iX Commands Reference Manual
Configuring Systems for Terminals, Printers, and Other
Serial Devices
HP 3000/iX Network Planning and Configuration Guide
Back up the System and Retain the Current Configuration
If you are installing over an existing system, ensure that
it has been thoroughly backed up. If up-to-date backups do not exist,
reschedule the installation. The backups provide a method of restoring
your data. Please refer to the HP e3000 MPE/iX System
Software Maintenance Manual if you need additional information
on backing up your system.
You should also retain a hard copy of your system's
current configuration. If you have a listing of your current configuration,
you can easily regenerate your system's current configuration,
if necessary. A customer-generated tape may contain configuration
data in the CONFIG.SYS group.
Use SYSGEN to modify the sample configuration file you used when you started
the system from the disk. For information on using SYSGEN, refer to
Chapter 4 "Using the System Generator (SYSGEN)" through
Chapter 8 "Modifying System File Configurations"
NOTE:Do not use these instructions to install your
system. This information is only an overview. Please refer to the HP
e3000 MPE/iX System Software Maintenance Manual for
complete installation information.
