Description: - 'active': indicates that the table row is available for
  use by the managed device;
- 'notInService': indicates that the table row
  exists in the agent, but is unavailable for use by the
  managed device (see NOTE below);
- 'notReady': indicates that the table row exists
  in the agent, but is missing information necessary in
  order to be available for use by the managed device;
- 'createAndGo': supplied by a management station
  wishing to create a new instance of a table row and
  to have it available for use by the managed device;
  (cannot be returned in a get response)
- 'createAndWait': supplied by a management station
  wishing to create a new instance of a table row but
  not to have it available for use by the managed device;
  and,
  (cannot be returned in a get response)
- 'destroy': supplied by a management station wishing
  to delete all of the objects associated with an
  existing table row.
  (cannot be returned in a get response)

To create new row, a manager sets this object to
createAndWait.  Agent creates a new row and sets row
status to notInService.  After the manager creates
all the corresponding rows in dptScsiArrMemberTable
and has set all the relevant columnar objects, it
finally sets dptScsiArrEntryStatus to active which
saves all the information to the hardware and performs
an array build.

If the manager sets dptScsiArrEntryStatus to active or
notInService and the required number of drives are
not members of this array group (for example, a RAID-5
needs at least 3 drives), then 'inconsistentValue' is
returned.

To delete an array group, the manager sets this object to
destroy. When a row with a particular row index is
destroyed, all corresponding rows in dptScsiArrMemberTable
are destroyed as well.
