OpenSolaris 2009.06 - man page for allocate (opensolaris section 1)

allocate(1)				  User Commands 			      allocate(1)

       allocate - device allocation

       allocate [-s] [-w] [-F] [-U uname] [-z zonename] device

       allocate [-s] [-w] [-F] [-U uname] [-z zonename] -g dev-type

       The allocate utility manages the ownership of devices through its allocation mechanism. It
       ensures that each device is used by only one qualified user at a time.

       The device argument specifies the device to be manipulated. To preserve the  integrity  of
       the  device's  owner,  the  allocate operation is executed on all the device special files
       associated with that device.

       The default allocate operation allocates the device special files associated  with  device
       to the uid of the current process.

       Only  authorized users may allocate a device. The required authorizations are specified in

       When the system is configured with Trusted Extensions, allocate runs the clean program for
       the  device  before it grants access to the caller to that device. For devices with remov-
       able media that have a mountable file system, allocate mounts  the  media  if  the  caller

       The following options are supported:

       -F device	 Force	allocates  either  free  or pre-allocated devices. This option is
			 often used with the -U option to allocate/reallocate devices to  a  spe-
			 cific	user. Only those users that have solaris.device.revoke authoriza-
			 tion are allowed to use this option.

       -g dev-type	 Allocates devices with a device-type  matching  dev-type.  The  dev-type
			 argument specifies the device type to be operated on.

       -s		 Silent. Suppresses any diagnostic output.

       -U uname 	 Uses  the  user  ID  uname instead of the user ID of the current process
			 when  performing  the	allocate  operation.  Only  a	user   with   the
			 solaris.device.revoke authorization is permitted to use this option.

       The following options are supported with Trusted Extensions:

       -w	      Runs the device cleaning program in a windowing environment. If a windowing
		      version of the program exists, it is used. Otherwise, the standard  version
		      is run in a terminal window.

       -z zonename    Allocates device to the zone specified by zonename.

       The following operands are supported:

       device	 Specifies the name of the device to be allocated.

       The following exit values are returned:

       0	      Successful completion.

       20	      No entry for the specified device.

       other value    An error occurred.

       Controlling Access to Devices

       The  functionality  described  in this man page is available only if  Solaris Auditing has
       been enabled. See bsmconv(1M) for more information.

       On systems configured with Trusted Extensions, the functionality is enabled by default.

       /etc/security/dev, mkdevalloc(1M), and mkdevmaps(1M) might not be supported  in	a  future
       release of the Solaris Operating Environment.
