Chapter 10. Installing Linux with kickstart 179
00: Storage cleared - system reset.
==> ipl cms
...
Do you want to IPL Linux from minidisk 100? y/n
n
Verify that you have a 512 MB virtual machine:
==> q v stor
00: STORAGE = 512M
This change is for the duration of the user ID session. When you log off and log back on
this user ID, the storage will go back to 256 MB.
3. Run rhel6 exec to initiate the kickstart. You see some initial kernel messages, followed by
the file system format and Red Hat Package Manager (RPM) package installation.
==> rhel6
...
Kernel command line: ramdisk_size=40000 root=/dev/ram0 ro ip=off
CMSDASD=191 CMSCONFFILE=linux02.conf-rh6
ks=nfs:9.60.18.223:/nfs/ks/linux02-ks.cfg
RUNKS=1 cmdline
...
4. The first time kickstart is run, the installer must format the DASD for Linux use. It is normal
to see error messages of the following format if the DASD you are using has never been
formatted. In subsequent kickstart installs, you should not see these errors:
end_request: I/O error, dev dasda, sector 0
Buffer I/O error on device dasda, logical block 0
Please wait while formatting drive dasda...
5. At the end of the kickstart, perform an IPL of the 100 disk to make any changes to your
RHEL 6 golden image:
/mnt/sysimage/dev done
/mnt/sysimage done
you may safely reboot your system
==> #cp ipl 100
00: zIPL v1.5.3 interactive boot menu
00: 0. default (linux)
00: 1. linux
...
Congratulations! You have now installed Linux onto the virtual server using kickstart. This
process can be repeated in the future for other Linux guests. For the purpose of this book, we
present a minimal installation with kickstart. However, you can completely customize the
kickstart file to install different packages based on your requirements. For more information
regarding kickstart options, see the documentation located at the following address:
http://www.redhat.com/docs/manuals/enterprise/
From there, click Installation Guide, then 28. Kickstart Installations.
Note: Towards the end of the kickstart, it is normal to see some unrecognized
characters on the panel. This is because the 3270 console cannot display the progress
meter during the post installation phase. To automatically clear the 3270 console and
avoid multiple panels of unreadable messages, issue the #cp term more 0 0 command
before running RHEL6 EXEC.
