Installing the Operating System
75
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 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.
INSTALL [{ ;START
;NOSTART }[options]]
where options are: START [;GROUP=cgn] [LOGON=acct]
[{ ;SINGLE-DISC [{ ;SINGLE-USER
;MULTI-DISC ]} ;MULTI-USER }]
[{ ;SYSSTART
;NOSYSSTART }]
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:
