MTU="4096"
The following parameters are required and must be included in the parameter file:
DASD=dasd-list
Where dasd-list represents the list of DASD devices to be used by Red Hat Enterprise Linux.
Although autoprobing for DASDs is done if this parameter is omitted, it is highly recommended to
include the DASD= parameter, as the device numbers (and therefore the device names) can vary
when a new DASD is added to the Red Hat Enterprise Linux guest. This can result in an unusable
system.
Additionally, in SAN-based environments, autoprobing in an LPAR-based install may have
unintended side effects, as the number of DASD and SCSI volumes visible may be unexpectedly
large and include volumes currently in use by other users. In particular, autoprobing during a
kickstart install (which may have enabled autopartitioning to clear all partitions) is highly
discouraged.
root=file-system
where file-system represents the device on which the root file system can be found. For
installation purposes, it should be set to /dev/ram0, which is the ramdisk containing the Red Hat
Enterprise Linux installation program.
The following parameters are required to set up networking:
SUBCHANNELS=
Provides required device bus IDs for the various network interfaces.
