To use the Device Allocation Configuration dialog box requires the configure device attributes authorization. Clicking the Configuration button in the Device Allocation Maintenance dialog box causes the Device Allocation Configuration dialog box to be displayed (see following figure).
The Device Allocation Configuration dialog box is divided into three parts:
Device security attributes--includes device name and type, minimum and maximum labels, clean program, and device map.
Allocation specifications--from Trusted Path or non-Trusted Path (for command line users), authorized users (with the authorizations specified in the Authorizations field), no users (if device is not allocatable), all users (if no authorizations required), and which authorizations to require for device allocation
Deallocation options--deallocate any allocated devices on reboot and deallocate any allocated devices on logout
