Sample Programs for LAN Control
D.2 Starting the NISCA Protocol
D.2.1 Start the Protocol
To start the protocol on a LAN adapter, perform the following steps:
Step Action
1 Use an account that has the PHY_IO privilege—you need this to run LAVC$START_
BUS.EXE.
2 Define the foreign command (DCL symbol).
3 Execute the foreign command (LAVC$START_BUS.EXE), followed by the name of the LAN
adapter on which you want to start the protocol.
Example: The following example shows how to start the NISCA protocol on LAN
adapter ETA0:
$ START_BUS:==$SYS$DISK:[ ]LAVC$START_BUS.EXE
$ START_BUS ETA
D.3 Stopping the NISCA Protocol
The sample program LAVC$STOP_BUS.MAR, provided in SYS$EXAMPLES,
stops the NISCA protocol on a specific LAN adapter.
Caution: Stopping the NISCA protocol on all LAN adapters causes satellites to
hang and could cause cluster systems to fail with a CLUEXIT bugcheck.
Follow the steps below to build the program:
Step Action
1 Copy the files LAVC$STOP_BUS.MAR and LAVC$BUILD.COM from SYS$EXAMPLES to
your local directory.
2 Assemble and link the sample program using the following command:
