SYNOPSIS    [Toc]    [Back]

     iopctl [-f ctldev] command [tid]

DESCRIPTION    [Toc]    [Back]

     The iopctl command can be used to  interrogate  and  control
I2O devices.

     The following options are available:

     -f ctldev    Specify the control device to use.  The default
is
                  /dev/iop0.

     The following commands are available:

     reconfig
             Reconfigure the IOP: ask all  bus  ports  to  rescan
their busses,
             and  attach or detach devices to and from the system
as necessary.

     showddmid tid
             Retrieve and display the DDM (device driver  module)
identity parameter
 group from the specified target.
