RE: High DASD utilization

["Raikov, Leonid" <Raikovl1@xxxxxxxxxxxxxxxx>]

Depending on the total configured DASD space working at 95% DASD can
result in severe objects fragmentation. If the total space is large
(e.g. 200GB), it may pass with no dire consequences. If not - it makes
sense to save/restore fragmented objects, that is if you know what they
are! That's why IBM usually recommend save/restore of the whole system.
