Stopping a Tape Device using SCF
Stopping a Tape Device using SCF
Use the SCF STOP command to terminate access to a storage device in an orderly
manner. This means that the device isn't stopped until current activity ends. When the
STOP command finishes, configured devices are left in a STOPPED state, substate
DOWN. The devices remain in the system configuration database.
When the last path to a device is stopped, an implicit refresh operation is also
performed. This is a general cleanup operation so that the device will not have any
changed buffers or file control blocks outstanding.
STOP Command Syntax
The syntax for the STOP command is:
OUT file-spec
Directs all SCF output generated for this command to the specified file.
FORCED
Specifies that the command should be executed without any interaction with
you, even if there are files open on the device. SCF will not prompt you for
confirmation.
SEL state
Specifies that the command should be applied only to objects that are in the
specified state.
Object-spec
Specifies one of the following combinations of object type and object name:
Wild-card characters are supported.
