Moving Plexes

Moving a plex copies the data content from the original plex onto a new

plex. To move a plex, 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 to vxplex.

• 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 plexes 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.
