FREEZE DEVICE and SUBDEVICE Commands
Use THAW DEVICE or SUBDEVICE to restore all the access authorities granted to
users on the ACL before access was frozen.
device-list
specifies one or more devices for which access is to be frozen. device-list can
be either:
device-name
( device-name [ , device-name ] ... )
device-name
can be any device name. The name can contain wild-card characters.
subdevice-list
specifies one or more subdevices for which access is to be frozen. subdevice-
list can be either:
subdevice-name
( subdevice-name [ , subdevice-name ... ] )
subdevice-name
can be any subdevice name. The name can contain wild-card characters.
WHERE WARNING-MODE
specifies that only devices or subdevices in filename-list that have
WARNING-MODE set are to be frozen.
Considerations
•
Freezing a device or subdevice that is currently open has no effect on processes
that have the device or subdevice open. However, if a process attempts to reopen
the device or subdevice after closing it, the Safeguard software returns a security
violation error (file error 48).
•
While a device or subdevice is frozen, the owners of the authorization record and
the primary owner’s group manager have all the access authorities (read, write,
and owner) for that device or subdevice.
The local super ID also retains ownership and has all the authority of any user or
group manager unless explicitly denied.
