Recall example
Figure 1 shows the results of recalls (either automatic
or by command) that allow DFSMShsm to select the volume to which the
data set is recalled. Because GROUP1.SAMPLE.A1 has the high-level
qualifier of GROUP1, for which a data set pool that contains the volumes
in User Group 1 was defined, it is recalled to one of the volumes
in that user group. Because U1234.G3.G4 migrated from a volume in
Volume Pool and a volume pool that contains those volumes was defined,
U1234.G3.G4 returns to one of the volumes in the pool. LARGE.ML.1
returns to one of the common volumes (general pool in JES3) because
neither of the following applies:
- It does not have the high-level qualifier to direct it to one of data set pools defined for the user groups.
- It did not migrate from one of the volumes in the volume pool.
