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:
1. Install from the backup or AUTOINST-created SLT and start the system.
2. Use VOLUTIL to initialize additional system volumes (if any).
3. Restore the latest partial and full backup tapes.
4. Shut down the system with the SHUTDOWN command,and rebootthe 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.
INSTALL [{ ;START
;NOSTART }[options]]
