Installation guide

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 recommen-
ded 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 unexpec-
tedly 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 in-
stallation 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.
qeth: SUBCHANNELS="read_device_bus_id,write_device_bus_id, data_device_bus_id"
lcs: SUBCHANNELS="read_device_bus_id,write_device_bus_id"
For example (a sample qeth SUBCHANNEL statement):
SUBCHANNELS=0.0.0600,0.0.0601,0.0.0602
The following parameters are optional:
• HOSTNAME=string
Where string is the hostname of the newly-installed Linux guest.
• NETTYPE=type
Where type must be one of the following: lcs, or qeth.
• IPADDR=IP
Where IP is the IP address of the new Linux guest.
• NETWORK=network
Where network is the address of your network.
• NETMASK=netmask
