Your installation can use DASDVOL access authority to designate users who can act as DFSMSdss storage administrators. DASDVOL access authority lets you perform any DFSMSdss function against the data sets on that volume. However, DASDVOL access is not supported for logical operations against SMS-managed data sets. Further, DASDVOL access authority must be granted in every volume for all the data sets for which you are the storage administrator.

DFSMSdss provides an alternative to DASDVOL access authority. Your installation can define special FACILITY class profiles to let you act as a DFSMSdss-authorized storage administrator.
