DASDVOL

DASDVOL is supported directly for volume-level operations, physical operations for both SMS-managed and non-SMS-managed data sets, and logical operations for non-SMS-managed data sets. With DASDVOL-access authority to a volume, you can perform DFSMSdss operations as described in Volume access and DASDVOL and DASDVOL limitations. When you do so, DFSMSdss bypasses access checking to the data sets and catalogs on that volume.

You have DASDVOL-access authority to one or more DASD volumes if all of the following are true:

DASDVOL class is active.
Profiles for the DASD volumes are defined in the DASDVOL class.
You have the level of access needed for the function you are trying to perform.

Instead of DASDVOL-access authority, your installation can authorize you to act as a storage administrator for one or more DFSMSdss operations. See DFSMSdss storage administrator for details.

Note: The system programmer or storage administrator uses ICKDSF to format tracks, write a volume label, and create a VTOC. The system programmer or storage administrator needs to have RACF® DASDVOL authority to do that. No one needs DASDVOL authority to allocate space on volumes. The system controls space on SMS volumes by other means such as ACS routines, storage group definitions, and Interactive Storage Management Facility (ISMF) commands.
