Installing under z/VM

•
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.
Update for Red Hat Enterprise Linux 5.3
Anaconda now supports both ports on CHPID for OSA Express3 cards. The installer will
prompt for the port number in the initial stage of the installation. The value provided for
the port also affects installed network interface startup script. When port 1 is selected, the
value "portno=1" is added to OPTIONS parameter of ifcfg-eth* file.
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.
Update for Red Hat Enterprise Linux 5.2
When installing on a System z guest for
Red Hat Enterprise Linux 5.2
, you can make the
mode persistent by adding either
LAYER2=0
or
LAYER2=1
to the CMS configuration file.
Use
LAYER2=0
when the OSA is in layer 3 mode, and
LAYER2=1
when the OSA is in
layer 2 mode.
When specifying
LAYER2=1
, you can also specify
VSWITCH=1
when connecting to a
VSWITCH
, or
VSWITCH=0
when connecting directly to the OSA. If a VSWITCH is not
in use, specify the MAC address in the CMS configuration file using the parameter
MACADDR=
<MAC address>
.
The following parameters for kickstart installations are optional:
•
RUNKS= value
Where
value
is defined as
1
if you want to run the installation program in noninteractive (kickstart)
mode in the 3270 terminal, or
0
otherwise.
•
cmdline
When
cmdline
is specified, 3270 terminal output becomes much more readable, as the installer
disables most escape terminal sequences that are applicable to unix-like consoles, but not
supported on the 3270 console.
