Dell EMC Metro node 7.1 Administrator Guide

PDF

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.
