NAME

     iopctl - a program to control IOP devices


SYNOPSIS

     iopctl [-f ctldev] command [tid]


DESCRIPTION

     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 pa-
             rameter group from the specified target.

     showdevid tid
             Retrieve and display the device identity parameter group from the
             specified target.

     showlct
             Display the driver's private copy of the logical configuration
             table.  This copy of the LCT matches the current device configu-
             ration, but is not necessarily the latest available version of
             the LCT.

     showstatus
             Display the current status of the IOP.

     showtidmap
             Display the device to TID map.
