Where cmsdasd_address represents the list of the device ID of the CMS DASD device which contains the configuration file. This is usually the CMS user's 'A' disk. This option is applicable only for users who have a CMS formatted disk (z/VM) available.

For example: CMSDASD=191

Where configuration_file represents the name of the configuration file. This value must be specified in lower case. It is specified in a Linux style file name format. The CMS file REDHAT CONF is specified as redhat.conf. This option is applicable only for users who have a CMS formatted disk (z/VM) available.

For example: CMSCONFFILE=redhat.conf

Where dasd-list represents the list of DASD devices to be used by Red Hat Enterprise Linux.

Although automatic probing 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 guest. This can result in an unusable system.

For example: DASD=0.0.0100,0.0201-0.0.0204

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"

Due to the length of the qeth command line, it has been broken into two lines.

For example (a sample qeth SUBCHANNEL statement):

SUBCHANNELS=0.0.0600,0.0.0601,0.0.0602

Where string is the hostname of the newly-installed Linux guest.

Where type must be one of the following: qeth or lcs.

Where IP is the IP address of the new Linux guest.

Where network is the address of your network.

Where netmask is the netmask.

Where broadcast is the broadcast address.

Where gw is the gateway-IP for your eth device.

Where mtu is the Maximum Transmission Unit (MTU) for this connection.

Where server1:server2:additional_server_terms:serverN is a list of DNS servers, separated by colons. For example:

DNS=10.0.0.1:10.0.0.2

Where domain1:domain2:additional_dns_terms:domainN is a list of the search domains, separated by colons. For example:

SEARCHDNS=example.com:example.org

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.

These variables can be used on systems with FCP devices to preconfigure the FCP setup (these can be changed during the installation).
