Installation guide

Where mtu is the Maximum Transmission Unit (MTU) for this connection.
DNS=server1:server2::serverN
Where server1:server2::serverN is a list of DNS servers, separated by colons. For example:
DNS=10.0.0.1:10.0.0.2
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 non-qdio mode.
When using qdio mode: osa_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_n="device_number SCSI_ID WWPN SCSI_LUN FCP_LUN"
The variables can be used on systems with FCP devices to preconfigure the FCP setup and can
be subsequently edited in anaconda during the installation. An example value may look similar
to:
FCP_1="0.0.5000 0x01 0x5105074308c212e9 0x0 4010"
n is an integer value (e.g. FCP_1, FCP_2, ...).
device_number is used to specify the address of the FCP device ( 0.0.5000 for device 5000,
for example).
SCSI_ID is specified in hex-value, typically sequential values (e.g. 0x01, 0x02 ... ) are used
over multiple FCP_ variables.
WWPN is the world wide port name used for routing (often in conjunction with multipathing)
and is as a 16-digit hex value (e.g. 0x5105074308c212e9).
SCSI_LUN refers to the local SCSI logical unit value and is specified as a hex-value, typically
sequential values (e.g. 0x00, 0x01, ...) are used over multiple FCP_ variables.
FCP_LUN refers to the storage logical unit identifier and is specified as a hex-value (such as
0x4010).
Note
Each of the values used in the FCP parameters (FCP_1, FCP_2, ...) are site-specific and are
normally supplied by the FCP storage administrator.
