If no device_clean script is specified at the time a device is created, the default script, /bin/true, is used.
Before You Begin
Have ready a script that purges all usable data from the physical device and that returns 0 for success. For devices with removable media, the script attempts to eject the media if the user does not do so. The script puts the device into the allocate error state if the medium is not ejected. For details about the requirements, see the device_clean(5) man page.
You must be in the root role in the global zone.
