Deleting an optical-disk-resident object from WORM media removes the directory entry for that object; however, the data itself remains on the disk, because of the write-once characteristic of the media. To ensure that confidentiality is maintained, it might be necessary to physically destroy disks that contain expired sensitive material. Follow the manufacturer’s directions to safely dispose of optical media.

When a delete request is issued for an object that resides on rewritable optical media, and the directory table entry for the object is deleted upon approval of the Auto-Delete Installation Exit, a row is added to the Deleted Object table in DB2 to indicate the object is to be deleted (physically erased). If the volume where the object resides is selected for a write request, LCS deletes all objects on the volume indicated within the Deleted Object table. LCS also deletes groups of objects when a drive completes a request and there are no other higher priority requests to perform.

When a delete request or transition to another level is completed for an object that resides on the filesystem, a row is added to the Filesystem Delete Table (FSDELETE) in DB2 to indicate that the object needs to be deleted (physically erased). A dedicated OAM task will run periodically to remove these objects from the filesystem.
