Communications Subsystems Summary
Depending on the communications subsystem, you may be able to use SCF commands
to perform the following changes online:
•
Add communications lines, devices, and subdevices
•
Delete communications lines, devices, and subdevices
•
Alter the characteristics of communications lines, devices, and subdevices
SCF cannot modify I/O processes while they are running—the I/O process must be
stopped, altered, and then restarted. Stopping an I/O process may affect application
availability.
For more information about SCF, refer to Section 7, “Tools for Online Change.”
Communications Subsystems Summary
Table 5-1 lists the communications subsystems that can be controlled by SCF, followed
by a description.
The information in Table 5-1 is current as of the publication date of this manual.
Products that do not support SCF are being modified over time to support these
interfaces. Consult the Subsystem Control Facility (SCF) Reference Manual for G-
Series Releases for the most up-to-date list of supported subsystems.
