SCF Command Example
Changes made with older SCF subsystems do not survive a system load or a reload of a
processor pair. You can bypass this limitation of SCF by setting up a command file that
contains all of your SCF changes. Invoke this command file when the system is loaded
(or have the command file execute from a system startup file) so that SCF changes are
reentered.
SCF Command Example
The following example shows how you would use SCF to alter the attributes of an
Expand line (LINE object).
Step 1: Stop the Expand Line
Use the STOP command to stop the appropriate LINE object. The following STOP
command stops an Expand LINE object named $LINEX:
SCF> STOP LINE $LINEX
Step 2: Alter the Expand Line
Use the ALTER command to alter the value of the attribute. The following ALTER
command changes the value of the L2TIMEOUT attribute for the Expand LINE object
named $LINEX:
SCF> ALTER LINE $LINEX, L2TIMEOUT 10.00
Step 3: Restart the Expand Line
Use the START command to restart the appropriate LINE object. The following START
command starts the Expand LINE object named $LINEX:
SCF> START LINE $LINEX
Where to Find More Information
The Subsystem Control Facility (SCF) Reference Manual for G-Series Releases provides
a general description of SCF, its features, and commands. Each product that has an SCF
interface has its own SCF reference manual. For example, for information about using
SCF with the Expand subsystem, you would read the SCF Reference Manual for
Expand.
Tandem Service Management (TSM)
The Tandem Service Management (TSM) package is a client/server application that
provides troubleshooting, maintenance, and service tools for your Himalaya S-series
server.
TSM combines and replaces many of the system maintenance functions previously
provided by the Sysheath toolkit, the Tandem Maintenance and Diagnostic Subsystem
(TMDS), and the Remote Maintenance Interface (RMI) product, all of which are
unavailable on S-series Tandem Servers.
