How To Resolve Scratch Shortages

Whenever the HSC cannot satisfy a library mount request for a scratch cartridge, the following message is issued:

... SHORTAGE ACS AA; MMMMMMMM; RRRRRRRR; SSSSSSSS; ...

This indicates that one of the following has occurred:

•there are no scratch cartridges in the ACS

•there are no scratch cartridges in the requested subpool in the ACS

•there are no scratch cartridges of the requested media type or recording technique in the ACS

•there are no scratch cartridges of the requested media type or recording technique in the requested subpool in the ACS.

The message identifies the media type (MMMMMMMM), recording technique (RRRRRRRR), and subpool (SSSSSSSS) of the scratch shortage.

Note: If the subpool name indicates “SUBPOOL 0”, this means one of the following:

•scratch subpooling is in effect and no subpool was specified

•scratch subpooling is not in effect.

If the recording technique specified in the request is 18-track, then the media type must be standard capacity with a recording technique of 18track, LONGItud, or not specified.
