Volume expansion method
Metro node recommends the best expansion method based on the geometry of the underlying device, using the
expansion-method attribute.
Possible values for the
expansion-method attribute are:
- storage-volume — Metro node expands the underlying storage volume (the corresponding LUNs on the back-end array).
- not supported — Metro node cannot expand the virtual volume because the volume did not meet one or more prerequisites. See
Limitations for details.
You can list the
expansion-method attribute using the CLI or Unisphere.
