Removing Nodes From the Network
Creating and starting Expand line-handler processes is explained in detail in Section II,
Configuring the Expand Subsystem.
Step 2: Start the lines
After the Expand line-handler processes are created and started, you must start the
communications lines using one of these Expand subsystem SCF commands:
START LINE $device_name
START PATH $device_name
Step 3: Verify that the lines have started
You can verify that the lines have started by using one of the Expand subsystem SCF
commands described in Table 18-10.
After the Expand lines have been started, the Expand software at the new node
automatically queries the existing nodes in the network for information about
accessible systems. The Expand subsystem then automatically selects the best path to
each accessible node and establishes end-to-end connections. The existing nodes
update their routing tables automatically.
Removing Nodes From the Network
This subsection explains how to remove a node from the network using the
management commands described in the preceding subsections. This explanation is
presented in two steps.
Note. Before you can start an Expand line-handler process, other processes might need to be
present and running in your system. For more information, see Section
II, Configuring the
Expand Subsystem.
Note.
Use the Expand subsystem SCF START PATH command for multi-line paths. The SCF
START LINE command affects the specified line and its associated path logical device; it does
not affect other lines in a multi-line path.
