recovering your Linux system
This section will provide information on how to recover your Linux
system should it be required.
the Linux rescue mode
The Linux Rescue Mode is a Linux environment that lets you access files
on your HP Visualize Linux workstation when you cannot actually run
Linux. You may be unable to run Linux because it will not boot or you
have had a hardware or software failure.
Linux may not boot if you have installed another operating system. Some
operating systems assume that you have no other operating systems on
your computer. When such an operating system is installed, it overwrites
the Master Boot Record that contained the Linux LILO bootloader. If this
happens, Linux will not boot.
Any computer can experience a hardware or software failure for many
reasons. With the HP Visualize Linux workstation, it might happen
because of problems with a hard drive or because LILO was not run after
building a new kernel.
Rescue Mode can give you access to the system so you can try to solve the
problem or, at least, make copies of important files.
booting your system in rescue mode
To boot your system in Rescue Mode, enter the following parameter at
the installation boot prompt:
boot: linux rescue
You can get to the installation boot prompt in one of these ways:
1. By booting your system from the diskette or CD-ROM that came with
your Red Hat Linux boxed set.
2. By booting from a network or PCMCIA boot diskette. These methods
assume your network connection is working and require you to
identify the network host and transfer type.
Once you have your system in rescue mode, a prompt appears:
bash#
