Installation guide
Update for Red Hat Enterprise Linux 5.3
Anaconda now supports both ports on CHPID for OSA Express3 cards. The installer will
prompt for the port number in the initial stage of the installation. The value provided for the
port also affects installed network interface startup script. When port 1 is selected, the value
"portno=1" is added to OPTIONS parameter of ifcfg-eth* file.
When installing under z/VM, you can add either PORTNO=0 (to use port 0) or PORTNO=1 (to
use port 1) to the CMS configuration file to avoid being prompted for the mode.
Update for Red Hat Enterprise Linux 5.2
When installing on a System z guest for Red Hat Enterprise Linux 5.2, you can make the mode
persistent by adding either LAYER2=0 or LAYER2=1 to the CMS configuration file. Use
LAYER2=0 when the OSA is in layer 3 mode, and LAYER2=1 when the OSA is in layer 2 mode.
When specifying LAYER2=1, you can also specify VSWITCH=1 when connecting to a VSWITCH,
or VSWITCH=0 when connecting directly to the OSA. If a VSWITCH is not in use, specify the
MAC address in the CMS configuration file using the parameter MACADDR=<MAC address>.
The following parameters for kickstart installations are optional:
RUNKS=value
Where value is defined as 1 if you want to run the installation program in noninteractive
(kickstart) mode in the 3270 terminal, or 0 otherwise.
cmdline
When cmdline is specified, 3270 terminal output becomes much more readable, as the installer
disables most escape terminal sequences that are applicable to unix-like consoles, but not
supported on the 3270 console.
Make sure that your kickstart file contains all required parameters before you use either of the
RUNKS of cmdline options.
If any of the network parameters required to make the network operate correctly are omitted from the
parm file, a prompt appears during the installation boot process.
If you logged off, reconnect and log in using z/VM guest ID you configured for installation. If you are
not in CMS mode, enter it now.
i cms
Use the downloaded REXX script redhat.exec that contains the commands necessary to IPL the
kernel image and start the installation. After having IPLed CMS, enter redhat on the 3270 console
and press the Enter key to execute this script.
The initial installation start-up script prompts you for information about your networking and D ASD s
unless you have specified all necessary information in the parm file.
