vdisk_ctrl(8)

NAME
     vdisk_ctrl - control virtual disk devices

SYNOPSIS
     vdisk_ctrl -c config-file

DESCRIPTION
     Vdisk_ctrl uses the information from a virtual disk configuration file to
     configure  virtual  disk  devices.  Virtual disks are explained in vd(4),
     and the configuration file format in vdisk.conf(5).

     The configuration file can be a minus sign to indicate standard input, to
     allow daring administrators to program virtual disks on the command line.
     ("vdn = null" is a handy way to unconfigure a virtual disk.)

OPTIONS

     -c   For now the only option: program virtual disks from a  configuration
          file.

FILES

     /etc/vdisk.conf     The configuration file used at boot time.

SEE ALSO
     vd(4), vdisk.conf(5), boot(8).

DIAGNOSTICS
     "Resource busy" messages if you try to reprogram a virtual disk  that  is
     in  use,  or  if you try to include a virtual disk in more than one other
     virtual disk, or into itself.
