       hotswap - register and unregister hotswappable  IDE hardware


       hotswap [ -c | --ide-controller N] [-h | --help] [-n | --nocheck] [-v |
       --verbose] [-V | --version] [ACTION]


       hotswap allows you to register and unregister hotswappable IDE devices,
       for example notebook computer modules, with the Linux kernel.

       It  has  been  developed  on and for a Dell Latitude C600, but does not
       rely on any specific properties of that machine.

       By default, the command line utility guides you through the hotswapping
       process  interactively.  It  is also possible to specify an ACTION, for
       example unregistering the current device, rescanning the IDE  bus,  &c.
       This  feature  is  primarily  intended  for  use  with  scripts and GUI
       frontends such as xhotswap(1).

       By using an XML configuration file, system administrators  can  specify
       arbitrary  shell  scripts  to  be  run before and after registering and
       unregistering devices.  This  is  particularly  helpful  for  automatic
       configuration  of CD-RW drives, which require SCSI emulation and bypass
       normal access via the IDE subsystem. By default, the configuration file
       is  located at /etc/hotswaprc; its syntax is described in hotswaprc(5).


       The program follows the  usual  GNU  command  line  syntax,  with  long
       options starting with two dashes (‘-’).

       -c, --ide-controller N
              Use IDE controller N.

       -h, --help
              Print a brief help text and exit successfully.

       -n, --nocheck
              Do  not  perform  sanity checks before attempting an action. Use
              with care, as this option may cause some steps to fail silently.

       -v, --verbose
              Print more information.

       -V ,--version
              Print version information and exit successfully.


       Besides the above options, the program allows you to specify one of the
       following actions on the command line:

              Detect the currently configured IDE device.

              Detect whether a file system on  the  currently  configured  IDE
              device is mounted.

              Unregister the currently configured IDE device.

              Scan  the IDE bus for a new device.  If a device has been found,
              register it with the kernel.

       If no ACTION is specified, interactive mode is entered.  In  this  mode
       the  program  guides you through the hotswapping process as appropriate
       for the current configuration.


       There is generally no need to manage floppy disk devices.  The  FDC  is
       always present and configured. Floppy disk drives do not connect to the
       IDE controller, even if they come in the same modules  as  IDE  devices
       and use the same connector.

       The  Linux  kernel  requires hotswappable devices to be the only device
       connected to their IDE controller.

       The mounted-ide action  assumes  file  systems  have  been  mounted  as
       /dev/hdc.  If  this  is not the case (i.e., you’ve used a symbolic link
       such as /dev/cdrom) the command will not work.


              The default location for the XML configuration file.
