Creating Wide Area Network (WAN) Subsystem
Devices
The network control process and Expand line-handler processes are defined as WAN
subsystem devices. The DEVICE object represents $NCP and Expand line-handler
processes in the WAN subsystem. You use the WAN subsystem SCF ADD DEVICE
command to create the network control process and Expand line-handler processes.
When you create a device using the SCF ADD DEVICE command, you must specify
the profile that the device will use. Multiple devices can use the same profile, allowing
you to create one profile for each type of Expand line-handler process. For example,
you could create a profile named SLHDIR to be used by all direct-connect line-handler
processes. The WAN subsystem SCF INFO PROFILE command lists the devices that
use a specific profile.
The SCF ADD DEVICE command also enables you to specify modifiers and modifier
values that will be used only by the device you are creating. These modifiers and
modifier values are part of the device record for the device and can be different from
the modifiers and modifier values in the profile used by the device. The modifiers and
modifier values used by a specific device are displayed by the Expand subsystem SCF
INFO PATH and INFO LINE commands. You can also display device-specific modifiers
using the WAN subsystem SCF INFO DEVICE command with the DETAIL option.
For more information about WAN subsystem SCF commands, refer to the WAN
Subsystem Configuration and Management Manual. For more information about
Expand subsystem SCF commands, refer to Section 15, Subsystem Control Facility
(SCF) Commands.
Starting the Expand Manager Process
The Expand subsystem requires that the Expand manager process ($ZEXP) be
running during network operation. To start the Expand manager process, enter the
following command at the TACL prompt:
RUN $SYSTEM.SYSnn.OZEXP / NAME $ZEXP, PRI 180, NOWAIT, CPU primary / backup
where primary is the number of the processor where the primary process will run and
backup is the processor where the backup process will run.
You can also start the Expand manager process at system startup by including the
following command in the system startup file:
OZEXP / NAME $ZEXP, OUT $ZHOME, PRI 180, NOWAIT, CPU primary / backup
To verify that the process is started, enter the TACL process-pair directory (PPD)
command at the TACL prompt:
PPD $
ZEXP
