Recalling files with optimization for tape

Tape processing is automatically optimized when you invoke dsmrecall with the filelist option and specify a file system.

About this task

If you do not specify a file system, the recall process does not optimize tape processing.

Procedure

Start a selective recall with the filelist=list_file option and specify a file system.

For example:

dsmrecall -filelist=myFileList myFileSystem

If the list file is a collection file that was generated by the dsmrecall command with the preview option, the recall begins immediately. The files are recalled in the order specified by the collection file.

If the list file is not a collection file that was generated by the dsmrecall command, and the list file is appropriately formatted, the file entries are sorted for optimized tape processing and are then recalled.

The recall begins immediately in the following example, because the file identified by the filelist parameter is a collection file.

dsmrecall -filelist=/HsmManagedFS/.SpaceMan/tapeOptimizedRecall/node_ID/PID/
FileList.ordered.collection myFileSystem
