STORGRP specifies that all of the online volumes in the storage group be dynamically allocated. If a volume in the storage group is not online, that volume is not used for processing. You can specify up to 255 storage group names. Specifying STORGRP with a storage group name is equivalent to specifying LOGDYNAM or LOGDDNAME with all the online volumes in the storage group included in the list.

You can specify the STORGRP keyword with the SELECTMULTI keyword, but STORGRP cannot be specified at the same time with the DDNAME, DYNAM, LOGDDNAME, or LOGDYNAM keywords.

Notes for LOGDDNAME, LOGDYNAM, and STORGRP keywords:

DFSMSdss selects from all data sets that are cataloged in the catalogs that are accessible through the standard search order if you do not specify the LOGINDDNAME, LOGINDYNAM, or STORGRP keyword.
When you specify the LOGDDNAME, LOGDYNAM, or STORGRP keyword, DFSMSdss still uses the standard catalog search order. However, DFSMSdss selects data sets only from the specified volumes.
You can process a multivolume data set that has extents on volumes when you specify the SELECTMULTI keyword if the following criteria are present:
- The volumes cannot be designated on the volume list that is created by the LOGDDNAME, LOGDYNAM, or STORGRP keyword.
- You must specify the SELECTMULTI keyword option (ANY or FIRST) to release a multivolume data set that has extents on volumes which are not identified with the LOGDDNAME, LOGDYNAM, or STORGRP keyword.

For more information about the SELECTMULTI keyword, see LOGDYNAM.
