Altering an X25AM I/O Process
For more information about the SCF ADD SU command and commands to manage
subdevices, see Section 4, SCF Commands for the X25AM Subsystem.
This completes the X25AM configuration procedure.
Altering an X25AM I/O Process
After an X25AM I/O process and its line are started, you might need to make changes
to the I/O process. To make persistent changes to an X25AM I/O process, you must
issue the SCF ALTER DEVICE command to the WAN subsystem. Perform these tasks:
1. Stop the line and its subdevices
2. Stop the I/O process
3. Change the I/O process modifiers
4. Start the I/O process
5. Start the line
6. Add the subdevices to the line
Figure 3-5 on page 3-12 illustrates making persistent changes to an X25AM I/O
process.
After you have changed the I/O process, you need to restart it using SCF START
DEVICE command to the WAN subsystem and then start the line using the SCF
START LINE command to the X25AM subsystem. Then you can add the subdevices to
the line and resume interacting with the line using SCF commands to the X25AM
subsystem.
An example sequence of commands to alter an I/O process is:
-> STOP LINE $x25p1
-> STOP DEVICE $ZZWAN.#x25p1
-> ALTER DEVICE $ZZWAN.#x25p1, V25, FIFO, ENABLECALLEDADDREXT
-> START DEVICE $ZZWAN.#x25p1
-> START LINE $x25p1
-> ADD SU $x25p1.#term, PROTOCOL ITI, DEVTYPE (6,0), &
-> RECSIZE 80, RPOA (125, 300, 5000)
For information about the SCF STOP LINE, START LINE, ADD SU commands, see
Section 4, SCF Commands for the X25AM Subsystem headings for these commands.
For more information about SCF STOP DEVICE, START DEVICE, ALTER DEVICE
commands, see the WAN Subsystem Configuration and Management Manual.
Caution. If you delete an X25AM I/O process by issuing the SCF DELETE DEVICE command
to the WAN subsystem, the X25AM line ceases to exist (it is deleted from the
system-configuration database when the I/O process is deleted).
