Selective recall processing

Use selective recall processing if you want to return specific migrated files to your local file system. When you selectively recall a group of files, they are recalled in the most efficient, time-saving order based on where they are stored.

For example, if some of your files are stored on a disk storage device and some of your files are stored on a tape storage device, the space management client recalls all of your files that are stored on the disk storage device first. It next recalls all of your files that are stored on the tape storage device. The access time (atime) changes to the current time when you selectively recall a migrated file.

To selectively recall files, use the dsmrecall command. For example the following command recalls a file named proj1rpt to the /home/proja directory:

  dsmrecall /home/proja/proj1rpt

The dsmrecall can also be invoked directly, by using a shell application or a script to build a list of files to be recalled. This file list can then be passed directly to HSM. For example, the following command recalls all files owned by user ibm:

  find /hsmmanagedfilesystem -user ibm -print > /tmp/filelist
  dsmrecall -filelist=/tmp/filelist
