Considerations
The START LAN command has the following syntax:
LAN lan-name
specifies the name of the LAN object to be started.
SEL [ NOT ] state
specifies the summary state select option. You can use the SEL option to specify that
you want to start only LAN objects in the STOPPED summary state.
Considerations
Consider the following points when using the START LAN command:
•
START LAN is a sensitive command requiring super-group access.
•
Before a LAN object is started the following requirements must be met:
°
The LAN object must be defined by using an ADD LAN command.
°
The RPC port mapper process, the TCP/IP process, and the TCP/IP subnetwork
object controlling the TCP/IP line must exist and be in the STARTED summary
state.
°
The LAN object must be in the STOPPED summary state.
•
Successfully starting a LAN object causes the SUBSYS object to enter the
STARTED summary state.
•
The LAN interface process does not run as a true process pair, but runs as a single
process with a persistent backup. If the primary processor in which the LAN
interface process is to run fails before the command is executed (and the specified
backup processor is up and running), the manager process automatically attempts to
restart the LAN interface process in the backup processor.
•
You can also start some LAN objects using the START SUBSYS command.
START SUBSYS starts all restartable LAN interface and server processes. You can
determine whether a LAN interface process is restartable by using the STATUS
LAN command.
•
If during initialization, the LAN interface process is unable to communicate with the
appropriate NonStop TCP/IP subnetwork object (the one that controls the TCP/IP
line to be used by the LAN object), the LAN interface process terminates, indicating
a fatal error, and the LAN object is returned to the STOPPED summary state. It is
the responsibility of the operator to restart the LAN object when the problem is
corrected.
•
To terminate the operation of a LAN object, use the STOP LAN or ABORT LAN
command.
