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 device_allocate(4).
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 removable media that
have a mountable file system, allocate mounts the media if the caller
The following options are supported:
Force allocates either free or pre-allocated devices.
This option is often used with the -U option to allocate/reallocate
devices to a specific user. Only those users that have
solaris.device.revoke authorization are allowed to use this
Allocates devices with a device−type matching
dev−type. The dev−type argument specifies the
device type to be operated on.
Silent. Suppresses any diagnostic output.
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
The following options are supported with Trusted Extensions:
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.
Allocates device to the zone specified by
The following operands are supported:
Specifies the name of the device to be allocated.

The invocation is Uncommitted. The options are Uncommitted. The
output is Not-an-Interface.
On systems configured with Trusted Extensions, the functionality is enabled by
/etc/security/dev, mkdevalloc(1M), and
mkdevmaps(1M) might not be supported in a future release of the
Solaris Operating Environment.
