Device-Clean Script for Tape Devices

The st_clean device-clean script is used for all tape devices.

The st_clean script uses the mt(1) command with the -rewoffl option to clean the device. When the script is run during system boot, it queries the device to see if it is on line and has any storage media in it. If necessary, the script prompts the operator to eject the storage media, and then it displays the appropriate label for the user to write on a physical label on the storage media.

Until deallocation completes, 1/4 inch tape devices are placed in the allocate error state, and 1/2 inch tape devices are taken off line. The allocate error state forces an authorized user to manually clean up the device before a user can allocate it again.
