ALTER VOLUME and SUBVOLUME Commands
2. Modify the attribute values specified in a LIKE clause by specifying the values for
the attributes you want to change in the ADD command. For example, this
command adds an authorization record for $DATA1 that has the same attribute
values as $DATA2 except for the OWNER attribute:
=ADD VOLUME $data1, LIKE $data2, OWNER sales.mike
ALTER VOLUME and SUBVOLUME Commands
ALTER VOLUME changes one or more attribute values in a volume authorization
record. ALTER SUBVOLUME changes one or more attribute values in a subvolume
authorization record.
An owner of a volume, the primary owner’s group manager, and the super ID can
change a volume authorization record. Similarly, an owner of a subvolume
authorization record, the primary owner’s group manager, and the super ID can
change a subvolume authorization record.
Except for the ACCESS attribute, specifying a new attribute value with either ALTER
VOLUME or ALTER SUBVOLUME replaces the current attribute value with the
specified value. Using ALTER to specify a new ACCESS access-spec adds the new
access-spec to the existing ACL for the specified volume or subvolume. To remove
existing ACL entries, use the minus-sign (-) form of access-spec.
volume-list
specifies one or more disk volumes for which authorization records are to be
changed. volume-list can be either of:
$volume
( $volume [ , $volume ] ... )
$volume
can be any volume name. The name can contain wild-card characters.
ALTER VOLUME volume-list [ , ]
{ LIKE [\system.]$volume | vol-subvol-attribute }
[ , vol-subvol-attribute ] ...
ALTER SUBVOLUME subvol-list [ , ]
{ LIKE [\system.][$volume.]subvol | vol-subvol-attribute }
[ , vol-subvol-attribute ] ...
