Expand If you use DSNM to control the Expand subsystem, you will find the following
information helpful. While it covers what you need to know about Expand from the
viewpoint of operating DSNM, it is not exhaustive. For more details on the Expand
subsystem, refer to the Expand Network Management Guide.
Object Types The Expand subsystem contains two object types, PATH and LINE. If you issue a
command for this subsystem without specifying the object type, the object type
defaults to LINE. The hierarchical relationship between paths and lines is shown in
Figure 5-2.

States Table 5-3 shows how DSNM reports Expand subsystem states.

UP STARTED
PENDING (none)
DOWN STOPPED
Note Table 5-3 is valid for the DSNM STATUS command. Because of the way that subsystems are
implemented, the NetStatus product and the DSNM INQUIRE command can report objects as pending,
which the DSNM STATUS command reports as either up or down. See Section 2, “DSNM Commands,”
for a discussion of the DSNM STATUS command.
