If you list the files on the tape cartridge, you can see that the file name changed. Compare Example 7-87 with the output from Example 7-85 on page 191. Although files are moved or renamed, recalls on those files are fine.

## 7.19 Reclamation 

The space on tape that is occupied by deleted files is not reused during normal IBM Spectrum Archive EE operations. New data is always written after the last index on tape. The process of reclamation is similar to the same named process in IBM Spectrum Protect (formerly Tivoli Storage Manager) environment because all active files are consolidated onto a new, empty, second tape cartridge. This process improves overall tape usage and utilization. 

When files are deleted, overwritten, or edited on IBM Spectrum Archive EE tape cartridges, it is possible to reclaim the space. The reclamation function of IBM Spectrum Archive EE frees tape space that is occupied by non-referenced files and non-referenced content that is present on the tape. The reclamation process copies the files that are referenced by the LTFS index of the tape cartridge being reclaimed to another tape cartridge, updates the GPFS/IBM Spectrum Scale inode information, and then reformats the tape cartridge that is being reclaimed. 

## 7.19.1 Reclamation considerations 

The following considerations should be reviewed before the reclamation function is used: 

GLYPH<SM590000> Reconcile before reclaiming tape cartridges 

It is preferable to perform a reconciliation of the set of tape cartridges that are being reclaimed before the reclamation process is initiated. For more information, see 7.15, “Repairing files to their resident state” on page 187. If this is not performed, the reclamation might fail with the following message: 

GLESL086I(01990): Reclamation has not completed since at least tape 058AGWL5 needs to be reconciled. 

GLYPH<SM590000> Scheduled reclamation 

It is preferable to schedule periodically reclamation for the IBM Spectrum Archive EE tape cartridge pools. 

GLYPH<SM590000> Recall priority 

Recalls are prioritized over reclamation. If there is a recall request for a file on a tape cartridge that is being reclaimed or for a file on the tape cartridge being used as the reclamation target, the reclamation job is stopped for the recall. After the recall is complete, the reclamation resumes automatically. 

GLYPH<SM590000> One tape cartridge at a time 

Only one tape cartridge is reclaimed at a time. The reclamation function does not support parallel use of drives for reclaiming multiple tape cartridges simultaneously.
