Moving Plexes
Moving a plex copies the data content from the original plex onto a new
plex. To move data from one plex to another, use the following command:
# vxplex mv original_plex new_plex
For a move task to be successful, the following criteria must be met:
• The old plex must be an active part of an active (ENABLED) volume.
• The new plex must be at least the same size or larger than the old
plex.
• The new plex must not be associated with another volume.
The size of the plex has several implications:
• If the new plex is smaller or more sparse than the original plex, an
incomplete copy is made of the data on the original plex. If an
incomplete copy is desired, use the -o force option.
• If the new plex is longer or less sparse than the original plex, the data
that exists on the original plex is copied onto the new plex. Any area
that is not on the original plex, but is represented on the new plex, is
filled from other complete plex(es) associated with the same volume.
• If the new plex is longer than the volume itself, then the remaining
area of the new plex above the size of the volume is not initialized and
remains unused.
