The chart that is shown in Figure 7-2 indicates how many seconds are required to reclaim all files in the source tape. With prior LTFS EE versions, this process takes around 1 second per file. Starting with IBM Spectrum Archive EE V1R1.1.3 (PGA2.2), it is almost 10 times faster when the source and the target tape cartridge are on the same node.

The yellow line shows performance just for a reference when scp  and ssh rm  commands are used on the same node by IBM Spectrum Archive EE. When the source and the target tapes are on a different node, the performance is worse than this reference because it requires metadata access to get the list of files in the source tape. In this case for the quick reconcile operation, the total time of reclamation might become longer than the case without the quick reconcile. 

The time required to have the quick reconcile varies by the number of files to be reconciled. The quick reconcile includes removing files that are not required anymore from an IBM Spectrum Archive EE tape. 

New messages are added to log so that a user can see the progress of the operation. Some examples are shown in Example 7-89. 

GLESR051I(01439): 17608 of 22000 files have been processed. GLESR052I(01505): Removing files from source tape TYO118L5. GLESR053I(01528): 1000 of 22000 files have been removed. 

When the option to limit the number of files for reclamation is used and one or more files remain in the source tape, the following message is shown in the log file: 

GLESL332I(ltfsee:4404): Reclamation has been partially performed. Run the reclamation again for tape JCA811JC.
