Air Cleaner User Manual

the installation proceeds without any input from the user. This occurs if all
required default information has been provided and the LVM information on the
backup media is compatible with the system to be installed. If, for example, the
prior physical volumes are not available or if there is not enough disk space on the
client, errors occur, and the installation process defaults to a prompted installation
as described in the remainder of this section.
If the installation defaults and backup data are compatible with the client system,
the installation proceeds as if you selected the Install the System with Current
Settings option from the Main Menu.
Note: This feature is not available with system installs from images stored in a
TSM server.
Handling Installation Errors
If an error occurs during installation, it occurs in one of the following ways:
1. If the error is a warning message only, the process displays the message and
proceeds normally.
2. If the error is recoverable, a message details the error, and you are given the
option of either continuing the installation process normally or entering a
system maintenance shell. From the maintenance shell (preceded by a ksh>
prompt), you can manually take whatever steps are needed to recover from the
error and then type exit to continue the installation.
3. During a no-prompt installation, codes are displayed in the system LED panel
indicating both the progress of the installation and if any errors have occurred.
If an error that required user intervention occurs, an LED c48 is displayed, the
detailed error is displayed on the system console, and the process defaults to a
prompted installation. Depending on the point of the error, you are either
prompted as described above or placed in the Installation and Maintenance
menus.
The system LED displays various codes during a tape or network boot process, as
well as various status messages during a no-prompt installation. Refer to
Appendix C, “LEDS”, on page C-1 for details on the LED codes.
The SysBack Installation and Maintenance Menu
To display the SysBack Installation and Maintenance menu, used to initiate a
SysBack system installation, the machine you want to install must first be booted
from either a SysBack system backup tape, CD or DVD, or a SysBack network boot
server.
Note: The Installation and Maintenance menu is not displayed when you perform
a no-prompt installation after booting unless an error has occurred in the
installation process due to an incompatibility between the information on
the backup and the system to be installed.
The instructions for booting the system vary for each boot type and also differ
greatly depending on the type of the machine to be booted. Example instructions
are provided in Appendix B, “Booting a System for SysBack Installation or
Maintenance”, on page B-1 for booting from either tape or network for various
hardware architectures. However, you should refer to the documentation that
accompanied your particular machine type for detailed instructions regarding
system boot procedures.
