    the vxvm object plex was introduced very long time ago in old versions like 2.* and 3.*, at that time, lvm was not popular at all.

    One of the reasons to have vxvm plex object is for dealing with very complex vxvm features which are way beyond contact volume layout (like layered vol, volume snapshot, site mirror, off-host data copy,storage tires, dg join/split etc)

      hi,

      i think that the plex is chosen in order to controll better the things over lvm.

      vxdisk will show disk online or offline?

      tnx
