Tableau TX1, User Manual

Page: 39 / 125

The TX1 also allows “shelving” of a DCO for source drives. When enabled for a given
source drive, the Shelve DCO feature will, after the Duplication job is started, disable the
DCO, complete the acquisition of the entire source drive, and then attempt to reapply
the original DCO setting back to the source drive. This provides a convenient way to
ensure that all source evidence is acquired and that the drive is returned to its original
state at the end of the duplication. See the source selection screenshot below for an
example of a selected source drive with the Shelve DCO feature enabled. See Disabling
HPA and DCO on page 97 for more details regarding drive DCOs and how TX1 supports
them.
