LUN Expansion (MetaLUN) CommandsUsing the added capacity of an expanded SnapView,MirrorView or SAN Copy LUNYou must perform the operations detailed in the following sections toexpand the capacity of a LUN or metaLUN that is currentlyparticipating in a SnapView, MirrorView or SAN Copy session (see“naviseccli metalun -destroy 20” on page 329), and to allow the hostto access the added capacity.Note: For a stripe expansion, any existing data is restriped across the originalLUN or metaLUN and the added LUNs during the SnapView, MirrorView orSAN Copy session. This restriping is invisible to the host.For LUNs in a SnapView sessionTo access the added capacity of an expanded snapshot source LUN,do the following:1. Stop all SnapView sessions and destroy all snapshots associatedwith the expanded source LUN (see the admsnap, the onlinehelp).2. Use the metaLUN -modify command on page 348 to change thecapacity of the expanded LUNs.3. Make sure the host operating system can utilize the addedcapacity.4. You can now start new sessions and create new snapshots withthe expanded LUNs (see the SnapView Command Line Interface(CLI) Reference and the online help).For LUNs in a clone groupNote: You must expand the clone and the clone source LUN to the same size.To access the added capacity of an expanded clone, or clone sourceLUN, do the following:1. For the clone, remove the clone form the clone group; for a clonesource LUN, destroy the clone group.2. Use the metaLUN -modify command on page 348 to change thecapacity of the expanded LUNs.350 EMC Navisphere Command Line Interface (CLI) Reference
