CONVERT: Specifying movement of data sets from one volume to another

Explanation: CONVERT is an optional parameter that you use to migrate all data sets, or a specific data set, from a level 0 volume to a migration level 1 volume and then immediately recall those data sets to another level 0 volume. You can use this parameter when you want to remove a volume from the system. The automatic class selection routines select the volume to which the data sets should be recalled.

The management class attribute PRIMARY-DAYS-NON-USAGE is not used for a MIGRATE CONVERT request. All eligible SMS-managed data sets are migrated to a migration level 1 volume. Before an SMS-managed data set is migrated, DFSMShsm determines whether or not the data is eligible to be expired.

Defaults: Automatic class-selection routines choose the volume and type of unit to which SMS data sets are recalled.

Note:

The management class attribute, LEVEL-1-DAYS-NON-USAGE, are not used when processing a MIGRATE CONVERT request. All eligible data sets are migrated to a migration level 1 volume.
If you specify the DAYS(days) parameter with the CONVERT parameter, the days value must be zero. The default is zero, and the only value allowed is zero.
