FREEZE VOLUME and SUBVOLUME Commands
Now these three subvolumes are no longer subject to Safeguard access control or
auditing. However, the Safeguard volume access controls remain in effect for any of
the subvolumes that reside on a disk volume protected by the Safeguard software.
FREEZE VOLUME and SUBVOLUME Commands
FREEZE VOLUME temporarily suspends the access authorities granted to users
through a volume ACL. While a volume is frozen, only the owners of the volume’s
authorization records, the primary owner’s group manager, and the super ID can
create or access disk files on the volume.
Similarly, FREEZE SUBVOLUME temporarily suspends the access authorities granted
to users through a subvolume ACL. While a subvolume is frozen, only the owners of
the subvolume authorization record, the primary owner’s group manager, and the
super ID can create or access disk files on the subvolume.
An owner of a volume, the primary owner’s group manager, and the super ID can
freeze a volume authorization record. Similarly, an owner of a subvolume authorization
record, the primary owner’s group manager, and the super ID can freeze a subvolume
authorization record.
To restore a frozen volume ACL, use the THAW VOLUME command. To restore a
frozen subvolume ACL, use the THAW SUBVOLUME command.
