ABORTIO



ABORTIO/=ABORTIO

     Aborts one pending I/O request for a device

SYNTAX

     ABORTIO ldev

     =ABORTIO ldev


PARAMETERS

ldev                The logical device number of the device for which
                    I/O is being aborted.


OPERATION

     This command aborts all pending I/O operations on the
     specified ldev.  To delete all queued I/O requests for a
     device, repeat the ABORTIO command until the following
     message is printed on the $STDLIST device:

     NO I/O TO ABORT FOR DEVICE #ldev

     Those devices which are JOB or DATA accepting always have
     outstanding READ requests pending, due to the auto-
     recognition feature of MPE/iX.  The ABORTIO command is used
     to clear these pending input requests.

     To completely clear spooled devices, several ABORTIO
     commands may be necessary.  Issue the ABORTIO command until
     there are no queued I/O requests, and the message above
     appears on the $STDLIST device.

     Clearing all outstanding I/O requests is sometimes required
     in order to allow proper execution of other console
     commands.  In certain cases, the ABORTJOB, TAKE, DOWN,
     and REFUSE commands will not execute unless an ABORTIO
     command is first issued to clear pending I/O operations on
     the appropriate device.

     If ABORTIO is not effective from the system console,
     =ABORTIO may be used. The =ABORTIO command should be used
     only when the ABORTIO command cannot be executed, or when
     the console is busy.  The =ABORTIO ([CTRL][A]) can be issued
     only from the physical console.

     This command may be issued from a session or job.  It is
     available from within BREAK or a program.  Pressing [Break]
     has no effect on this command. =ABORTIO ([CTRL][A]) is
     available only at the physical console, unless distributed to
     users with the ALLOW or ASSOCIATE command.  =ABORTIO cannot
     be issued from a job.


EXAMPLE(S)

     To abort all pending I/O requests for logical device 53,
     enter

     ABORTIO 53
     1116/3/NO I/O TO ABORT FOR DEVICE 53

     You must issue several ABORTIO commands to abort all pending I/O
     operations on a spooled device, as shown below:

     STOPSPOOL 5
     1120/31/SP#5/STOPPED
     1120/31/LDEV#5 NOT READY
     REFUSE 5
     ABORTIO 5
     ABORTIO 5
     1121/40/NO I/O TO ABORT FOR DEVICE 5
