5. Reinstall from a System Backup
A
System Backup
may be used to reinstall either the original system or a different system with either the same
or different hardware configuration. To initiate the installation, you must first boot the client from CDROM,
network boot server, or local (internal, or external/portable) disk, using the instructions found in the section
Booting to the System Installation Process
To setup a client system to be installed from a System Backup on a network install server, you must first
configure it using the process described in the section
Enable/Disable Network Installation of a Client
Cloning Systems
"Cloning" a system means to install a system from a backup originating on another system. The system from
which the backup was made may be identical or completely different than the system you are installing.
If the system to be installed is identical in hardware type and configuration to the one the backup was made
from, the installation may be performed with no customization required. However, if the systems differ, there
may be changes required. For instance, if the disk configuration on which the volume groups were placed is not
available on the new system, messages will be displayed that the original disks are not available and you must
select new physical volumes into which the volume groups will be placed. See
.
No-Prompt Installation
If the system is set to
no-prompt installation
, the
Installation and Maintenance Menu
will not appear (as
described in the following section), but the installation will proceed without any input from the user. If your boot
media was created for a no-prompt installation, a banner will display as follows:
As indicated, you will have 60 seconds to turn off the system to prevent the system recovery process from
continuing (and possibly overwriting all data on the system). There is no way to manually interrupt an install
process created for no-prompt installation and cause it to display the installation menus.
However, if any error occurs, such as an install server or device not being available, or if the backup data read
from the installation media cannot be installed onto the detected hardware without user intervention, an error
message will occur and the
will appear.
Refer to
Enable/Disable Network Installation of a Client
answer any questions normally asked during the install process which are required for a no-prompt installation.
If configured for no-prompt installation, the installation process will proceed automatically as follows:
1. The defined install server and device will be checked to ensure they are available and readable
2. The selected backup will be read and the installation information will be extracted
