HP File System Extender (FSE) manual Reorg-scan, ExpirationDate, NumberOfGenerations, Reorg-stat

2.10 NAME 83

•– –enable

Enable operation of FSE partition Name, which is currently disabled.

•– –reorg–scan

Scan FSE medium volumes on all media that belong to the FSE partition Name for obsolete data using the mandatory ExpirationDate and optional NumberOfGenerations parameter. The scan statistics are recorded in the corresponding File System Catalog, in order to be used by the reorganiza- tion job. Note that the scanning process may take a considerable amount of time. For more information on the media reorganization, see the FSE user guide.

•ExpirationDate

Treat all migrated file data generations that were created after Expiration- Date as valid. You have to specify the ExpirationDate parameter in the form of "YYYY/MM/DD HH:mm:ss" or "YYYY/MM/DD". In the latter case, the time 00:00:00 is assumed. Note that if additional NumberOfGenerations parameter is specified, not all such generations may be preserved by the reorganization process. This depends on the actual value of NumberOf- Generations.

•NumberOfGenerations

Treat at most NumberOfGenerations latest migrated file data generations as valid. Specifying this parameter, you can reduce the number of generations that would be preserved using the ExpirationDate parameter alone.

•– –reorg–stat

Display the statistics gathered by the reorganizational scan job that was run on the FSE partition Name. The reported values / statistics are displayed for each belonging FSE medium, and are the following:

1.Barcode .......... FSE medium barcode,

2.VolNum .......... number of FSE medium volumes on the medium,

3.ValidData .......... amount of valid (non–obsolete) data stored on the medium (in MB),

4.Total .......... total amount of data stored on the medium (in MB),
