LINUX (RE)INSTALLATION
In the event the Linux operating system has to be reinstalled for what ever reason, a
Redhat Enterprise Linux DVD is included with the computer system. This DVD is a merge
of the latest iso-
CD’s, downloaded from the Redhat website and additional software. Bear
in mind that at least the home-directories: /home/beams and /home/pg are backup-ed for
a full recovery of the system, as discussed in previous chapter.
To reinstall Redhat Enterprise Linux, put the DVD into the DVD-drive. Be sure the BIOS
tries to boot from the DVD-drive before the hard disk or the raid-device.
From the included DVD two installation ways are possible:
-
Standard from a kickstart file
-
Manual Linux installation
11.1.
Standard from a kickstart file
The DVD has a kickstart file which contains the entire installation of the system as how it
is delivered. This includes all packages from the Linux distribution and also extra required
packages. When this option is chosen, everything will be installed automatically without
any interaction of the user. The requirement is that the system is a Z820 as described in
the chapter “System Specific Information”.
When the welcome screen with the installation options appears on the screen as in figure
above, then a timeout counter counts down from 60 to 0 seconds. When the counter is 0,
then it will start with the default installation option: “Install or upgrade an existing system”.
For the “standard installation” this is not correct. Thus select with the up/down arrow keys
the option: “
a217”
before the counter has reached 0.
By selecting “
a217”
, the automatic standard installation procedure begins and will install
everything what is needed to control the EBPG5200: a217, including the EBPG5200
control software BEAMS with the user accounts etc. etc.
