Appendix B. Sample Parameter Files 41
SEARCHDNS=<domain1>:<domain2>:...:<domainN>
Where <domain1>:<domain2>:...:<domainN> is a list of the search domains, separated
by colons. For example:
SEARCHDNS=example.com:example.org
PORTNAME=<osa_portname> | <lcs_portnumber>
This variable supports OSA devices operating in qdio mode or in non-qdio mode.
When using qdio mode: <qeth_portname> is the portname specified on the OSA device
when operating in qeth mode. PORTNAME is only required for z/VM 4.3 or older without
APARs VM63308 and PQ73878.
When using non-qdio mode: <lcs_portnumber> is used to pass the relative port number as
integer in the range of 0 through 15.
FCP_* (FCP_1, FCP_2, ...)
These variables can be used on systems with FCP devices to preconfigure the FCP setup (these
can be changed during the installation).
Use the following samples as a guide to formatting proper parameter files.
Sample file with minimally required parameters:
root=/dev/ram0 DASD=200
Note
The Red Hat Enterprise Linux installation program prompts the user for any required parameters not
specified in the parameter file.
Sample file configuring a CTC networking device:
Example of redhat.parm file:
root=/dev/ram0 ro ip=off ramdisk_size=40000
CMSDASD=191 CMSCONFFILE=redhat.conf
