Open System Services NFS Management and Operations Guide

Adding a LAN Interface Process
A LAN object is a LAN interface process that accepts requests from the LAN and passes them on
to other OSS NFS objects for processing. The ADD LAN command is used to add a LAN object
to the subsystem.
A LAN object can be added at any step during configuration of the OSS NFS subsystem. However,
do not start a LAN interface process until the end of the configuration process. Once the LAN
interface process is running, OSS NFS clients can begin using OSS NFS services even though the
OSS NFS subsystem might not be fully configured. Permitting OSS NFS clients premature access
might compromise security by allowing access to directories that otherwise would be secured. To
avoid this risk, completely configure the OSS NFS subsystem before starting the LAN interface
process.
Considerations
• In addition to the lan-name, you are required to supply these attributes to the ADD LAN
command:
CPU cpu-number
specifies the processor number of the primary processor (0 through 15) on which the LAN
interface process runs.
PROGRAM file-name
specifies the Guardian filename of the LAN interface program. If you used the default subvolume
and file ID when installing the OSS NFS subsystem, you should set this attribute to
$SYSTEM.ZOSSNFS.NFSLAN.
PROCESS process-name
specifies the process name of the LAN interface process.
• Unless memory and processor availability dictates otherwise, always configure the BACKUP
attribute when adding the LAN process.
• The LAN interface process must be the last process started through SCF.
Example
This example adds and starts a LAN object and starts the LAN interface process:
ASSUME $ZNFS
ADD LAN LAN, &
PROCESS $LAN0,&
PROGRAM $SYSTEM.ZOSSNFS.NFSLAN,&
CPU 0,&
BACKUP 1,&
PRI 185,&
TCPIP-PROCESS-NAME $ZTC0,&
TCPIP-HOST-FILE $SYSTEM.ZTCPIP.HOSTS,&
HISTOGRAM (128, 256, 512, 1024, 2048, 4096)
START LAN LAN
Starting PCNFSD
The PCNFSD process is invoked using these TACL commands.
