Installing the Operating System
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:
