3.23 Using the Installation Disks in Rescue Mode

You can use the installation disks in rescue mode, in case your LPAR will not boot. Rescue mode gives
you access to the disk partitions on your LPAR so you can make any changes necessary to rescue your
installation.
To boot in rescue mode, follow the instructions for booting the installation program, with this change:
In the NWS Description, set the IPL parameters option to 'rescue' (including the quotes), or to
'dd rescue' if you need to load the SCSI driver.
After the Language Selection screen (see Section 3.4, Language Selection), the installation program
will attempt to mount the disk partitions on your LPAR. It will then present you with a shell prompt
where you can make the changes you need. These changes may include storing the kernel and com-
mand line into the IPL source, as described in the Installation Complete section (see Section 3.22,
Installation Complete).
When your changes are complete, you can exit the shell using exit 0. This will cause a reboot from
the side. To reboot from the or side or from , you should vary off the LPAR instead

of exiting the shell.
