Booting into emergency mode

Booting into emergency mode

In emergency mode, you are booted into the most minimal environment. The root file system is mounted read-only and the setup is minimal.

The advantage of emergency mode over single-user mode is that the init files are not loaded. If init is corrupted or not working, you can still mount file systems to recover data that could be lost during a reinstallation.

To boot into emergency mode, use the same method as described for single-user mode in Booting into single-user mode.

On an x305 IBM Server system using GRUB as the boot loader, use the following steps to boot into emergency mode:

1.If you have a GRUB password configured, type p and enter the password.

2.Select Red Hat Enterprise Linux with the version of the kernel that you wish to boot and type a to append the line.

3.Go to the end of the line and type emergency as a separate word. Press [Enter] to exit edit mode.

Tip:

Press the [Spacebar] and then type emergency.

4.Back at the GRUB screen, type b to boot into single-user mode.

-On an x305 IBM Server system using LILO as the boot loader, at the LILO boot prompt, type: linux single

Note:

If you are using the graphical LILO, press Ctrl-xto exit the graphical screen and go to the boot: prompt.

- For all other platforms, specify emergency as a kernel parameter at the boot prompt.
