The purpose of inventory is to identify new tapes and recognize tapes DPM has seen before.
A fast inventory involves reading the bar code of each tape in the library. DPM can perform a fast inventory for tapes that have bar codes in a tape library that has a bar code reader.
A detailed inventory involves reading the header area of a tape in the library to identify the on-media ID (OMID) on each tape. DPM must perform a detailed inventory when a tape does not have a bar code or the tape library does not have a bar code reader.
A fast inventory detects any tape (with or without a bar code) in any library. However, to uniquely identify the media, perform a detailed inventory.
 Note |
|---|
| If a cleaning tape does not have a bar code or the bar code does not start with "CLN" is added to the library, and you run a detailed inventory before you mark the tape as a cleaning tape and run a fast inventory, a cleaning job will start when DPM mounts this tape during the detailed inventory. |
