Installation guide

PORTNAME=osa_portname | lcs_portnumber
This variable supports OSA devices operating in qdio mode or in 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.
PORTNO=portnumber
When installing under z/VM, you can add either PORTNO=0 (to use port 0) or PORTNO=1 (to
use port 1) to the CMS configuration file to avoid being prompted for the mode.
The PORTNO= setting also works on LPAR, but you must place it directly in the parmfile
rather than the CMS configuration file.
LAYER2=
Add either LAYER2=0 or LAYER2=1 to the CMS configuration file to make the mode
persistent when installing on a System z guest.
Use LAYER2=0 when the OSA is in layer 3 mode, and LAYER2=1 when the OSA is in layer 2
mode.
VSWITCH=
When specifying LAYER2=1, you can also specify VSWITCH=1 when connecting to a
VSWITCH, or VSWITCH=0 when connecting directly to the OSA.
MACADDR=MAC_address
When specifying LAYER2=1 and a VSWITCH is not in use, you can use this parameter to
specify the MAC address in the CMS configuration file.
FCP_* ( FC P_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.

Note
The installation program prompts the user for any required parameters not specified in the
parameter file.
