Protecting z/VM Minidisks

You can use RACF® to control who can link to z/VM® minidisks using profiles in the VMMDISK resource class. z/VM calls RACF for an authorization check in the VMMDISK class for two different events:

1. LINK command—A user's attempt to link to another user's minidisk.
2. MDISK event—A user linking to his or her own minidisk. MDISK events occur at logon time when the user's MDISK directory statements are being processed, or when the user issues a LINK command for a self-owned minidisk.
