Using the Subsystem Control Facility (SCF)
RESET Puts an object in a state from which it can be started. The RESET
command moves an object to a STOPPED state, substate DOWN from
any state except the STARTED state (in which state RESET is ignored).
RUN Runs another program from within SCF.
SAVE Archives a copy of the CONFIG configuration database file.
SETMANAGER Allows the explicit setting of a subsystem manager process name.
SETPROMPT Changes the information contained in the command-line prompt.
START Initiates the operation of an object (makes a stopped device accessible to
user processes). If successful, leaves the object in a STARTED state.
STATS (Does not support TAPE device in G-series releases) Displays the
accumulated statistics for an object and optionally resets them.
STATUS Displays current status information about an object.
STOP Terminates access to a storage device in an orderly manner. The device is
not stopped until current activity ends. When the STOP command is
done, configured devices are left in a STOPPED state, substate DOWN.
Devices remain configured in the system configuration database.
STOPOPENS (Does not support TAPE device in G-series releases) Prevents any
additional opens to an object.
SUSPEND Restricts the use of the connections both to and from an object.
Application requests, except close requests, are rejected. The SUSPEND
command places the object into the SUSPENDED state.
SWITCH (Does not support TAPE device in G-series releases) Causes the primary
path to become the backup path, and the backup path to become the
primary path. For disks, the SWITCH command designates the preferred
ServerNet addressable controller (SAC) path for any magnetic disk
accessible through dual paths.
SYSTEM Sets the default system name for all file-name and object-name
expansion.
TELL Sends a text-string message to a subsystem.
TIMEOUT Allows the user to vary the amount of time SCF waits for a response
from SCP before canceling the request.
TRACE Captures trace information (activity) of one or more selected objects.
VERIFY Tests an object for its ability to meet an object-specific subsystem quality
control objective.
VERSION (Does not support DISK or TAPE devices in G-series releases) Displays
the version level of SCF, SCP, or the current subsystem.
VOLUME Sets default volume and subvolume names for all file-name expansion.
! Reexecutes a command line.
? Displays a specific command line.
