Device Allocation Databases and Commands

If you do not have access to the Device Allocation Manager, you can use the commands below to administer allocatable devices. The commands use the device databases: device_allocate(4), device_deallocate(4), and device_maps(4) . Note that the commands are not intended for non-administrative users.

• add_allocatable(1M)--adds devices to the allocation databases.

• allocate(1M)--manages the ownership of devices through its allocation mechanism. It ensures that each device is used by only one qualified user at a time.

• deallocate(1M)--deallocates a device allocated to the evoking user.

• list_devices(1M)--lists the allocatable devices in the system according to specified qualifications.

• dminfo(1M)--displays information about device entries in the device maps file.
