Attributes Within Volume Groups
Each volume’s attributes within a numerical volume group must
be uniform. For example, if the first volume in a numerical
volume group has been formatted with compression ON and a
block size of 64 KB, all the volumes in that volume group will
have these identical attributes.
If you reassign media from one volume group to another
volume group (with the volgroup -f option), AMASS makes
sure the media attributes from the first volume group match the
attributes of the second volume group. If the values do not
match, AMASS issues an error and does not complete the
reassignment. For information on numerical volume groups, see
“Volume Groups Defined” on page 1-13.
