Commands With a SUB or SEL Parameter
Commands With a SUB or SEL Parameter
Many SCF commands permit the use of the command parameters SUB and SEL.
•
You can use SUB to specify which subordinate objects the command affects. For
example, you might want to start all the X.25 objects subordinate to X.25 lines
currently not started. One way to do this is with the following command:
-> START LINE $X25, SUB ONLY
•
For some subsystems, you can use the SEL parameter to specify that the
command is effective only if the object or objects are in the specified state. A
command like the following is used to do this:
-> STATUS SU $TR3271.*, SEL STARTED
SCF Object States
Objects have operational states, such as STOPPED or STARTED. The exact
sequence of states an object goes through varies from object to object and from
subsystem to subsystem. Some subsystem commands recognize only a few states.
Applicable states are described in the manual for each subsystem, as listed on
page xii.
Table 3-1 lists the following object states recognized by SCF.
Table 3-1. SCF Object States
State Description
ABORTING The object is being stopped without regard to the current state of its
operation. Typically, this state is triggered by an ABORT command or by
a device malfunction. In this state, no new links are allowed and drastic
measures are applied to reach the STOPPED state.
DEFINED The object is known (defined) to the subsystem. In this state, a
nonconfigured object (as described on page 5-2
) is known to the
subsystem, but has no link established to or from it.
DIAGNOSING The object is being tested by a diagnostic process.
SERVICING The object is unavailable due to a pending service operation.
STARTED The object is initialized and ready for normal operations.
STARTING The object is being initialized and is attempting to start.
STOPPED The object is not ready for normal operations. STOPPED is equivalent to
down, not ready, or killed, as used by other applications.
STOPPING The object will be stopped after all current operations are complete. The
object is in the STOPPING state if its next state is expected to be
STOPPED. No new links are allowed either to or from it. If current links
exist, they are in the process of being deleted.
