Autopick Facility › Scratch Volume Availability

Scratch Volume Availability

Volumes are eligible for use as scratch tapes if they meet these criteria:

• The scratch bit (SCRATCH) in the volume’s TMC record is on.
• The delete bit (DELETED) in the volume’s TMC record is off.
• The media error bit (BADMEDIA) in the volume’s TMC record is off.
• The OUTCODE field is cleared.
• The site-defined EDITDEF field does not contain the reject threshold value specified on the AUTOPICK configuration file record.

Note that any reject action other than writing a type 3 audit record renders a volume unavailable for automatic scratch selection. To make the volume eligible again, the tape librarian must take specific action (clearing the OUTCODE, resetting the delete bit, or changing the value of the site-defined EDITDEF field).
