object that is enumerated by <span><a href="9da03776-bcf7-4a34-97a7-cc8ba5d561a0" data-linktype="relative-path">VDS_VOLUME_PLEX_STATUS</a></span>.
The status of the plex need not match that of the volume to which it belongs.
For example, a volume plex can have a failed status (VDS_VPS_FAILED), but if
the volume is <span><a href="8eef5d42-22d7-4302-aed9-12face91505a#gt_98c2ba19-d0f7-4db1-b6c1-4e7323cc5bc0" data-linktype="relative-path">fault-tolerant</a></span> and

enumeration that defines the health of the volume. The health of the plex need
not match that of the volume to which it belongs. For instance, a volume&#39;s plex
can have failed health (VDS_H_FAILED), but if the volume is a mirror volume
(RAID-1) and its other plexes are healthy (VDS_H_HEALTHY), the volume will have
failed redundancy health (VDS_H_FAILED_REDUNDANCY).</p><p><b>TransitionState:</b>  Value from the <span><a href="60f46f25-7c04-4427-9099-d7b75410d33e" data-linktype="relative-path">VDS_TRANSITION_STATE</a></span>
enumeration that defines the configuration stability of the plex. The
TransitionState of the plex matches the TransitionState of the volume to which
it belongs.</p><p><b>ullSize:</b>  The size of the plex, in
bytes. The size can be equal to, or greater than, that of the volume to which
it belongs. The plex cannot be smaller than the volume.</p><p><b>ulStripeSize:</b>  The stripe interleave
size, in bytes. This member applies only for plexes of type VDS_VPT_STRIPE
(striped) and VDS_VPT_PARITY (striped with parity).</p><p><b>ulNumberOfMembers:</b>  The number of
members (<span><a href="8eef5d42-22d7-4302-aed9-12face91505a#gt_671c4d19-364a-471c-bc1a-8d7893952fa9" data-linktype="relative-path">RAID columns</a></span>) in the
