ACF2 RESVOLS GSO record value must be set to Volmask(-). Any other setting requires documentation justifying the change.

The RESVOLS record defines DASD and mass storage volumes for which CA ACF2 is to provide protection at the data set name level. Information at rest refers to the state of information when it is located on a secondary storage device (e.g., disk drive and tape drive, when used for backups) within an operating system.

This requirement addresses protection of user-generated data, as well as operating system-specific configuration data. Organizations may choose to employ different mechanisms to achieve confidentiality and integrity protections, as appropriate, in accordance with the security category and/or classification of the information.

From an ACF command screen, enter: SET CONTROL(GSO) LIST RESVOLS
