SMS-managed volume

Assume that you want to remove volume SG2002 from the system and replace it with a new volume. You must do three things:

Prevent new allocations to volume SG2002
Remove the data sets that DFSMShsm can process from the volume
Remove the data sets that DFSMShsm cannot process from the volume

To prevent new allocations to the volume, you must change the status of the volume in the storage group. For example, you can establish the volume status in the storage group definition as shown in Figure 1.

Figure 1. SMS Volume Status

     STORAGE GROUP NAME: STGGP2
     VOLUME SERIAL NUMBER: SG2002

        SYSTEM        SMS VOL
        NAME          STATUS
       --------       --------
       PROCUN1  ===>  DISNEW
       PROCUN2  ===>  DISNEW
       PROCUN3  ===>  DISNEW

To remove the data sets that DFSMShsm can process, you can issue the following command:

MIGRATE VOLUME(SG2002 MIGRATE(0)) CONVERT

DFSMShsm migrates all of the data sets that it can process off of volume SG2002 and recalls them to other SMS-managed volumes. The DFSMSdfp automatic class selection routine selects the volume for data set recall.

To move any data sets that DFSMShsm cannot process, you can use DFSMSdss.
