The RECALL command recalls a migrated data set. If you want, you can specify the volume and type of unit where DFSMShsm is to recall the data set.
If you specify the volume and type of unit when recalling an SMS-managed data set, the volume and unit type will be passed to the automatic class selection (ACS) Routines. ACS ultimately determines to which volume the data set is recalled.
The FORCENONSMS parameter allows the ability to force recall of an SMS-managed data set to a non-SMS-managed volume. It is not possible to convert a data set that is not extended format to a data set that is extended format during a recall. However, you can convert an extended format data set to a data set that is not extended format during a recall, if you specify the FORCENONSMS optional parameter.
If you do not specify the target volume for a recalled non-SMS-managed data set, and the data set migrated from a primary volume whose primary volume attribute was automatic backup or automatic migration, DFSMShsm automatically tries to recall it to a primary volume having the same set of attributes as the volume it migrated from. If no volume is found and the UNLIKE subparameter was specified with the SETSYS RECALL command, then DFSMShsm can recall to a volume that has unlike attributes.
If a host is connected to a common recall queue (CRQ), recall requests are sent to the CRQ. For information about the common recall queue functions, see z/OS DFSMShsm Implementation and Customization Guide.
